The Draper SP-KSM-3-Position Key Switch (Momentary) is the advanced upgrade your control panel has been waiting for. This sophisticated device replaces the standard KS-3 three-position key switch with a momentary, spring-loaded action that delivers precise Up and Down directional control while preserving the security of a keyed mechanism. Built for reliability in demanding environments, the SP-KSM-3 marries effortless operation with robust security, making it an ideal solution for single- or multi-station control systems across manufacturing lines, stage rigging, automated equipment, and other applications where intentional control and access security are critical. When you need a switch that combines operational clarity with protection against unauthorized use, this Draper innovation stands out as a trusted choice for engineers and technicians who demand performance and peace of mind from every press or key turn.

  • Momentary Up/Down action with secure key control: This switch delivers precise, spring-loaded directional actuation (Up and Down) while the key mechanism ensures that only authorized personnel can operate the system. The momentary design guarantees that the circuit is completed only while the handle is engaged, reducing the risk of unintended actions and offering a crisp, tactile response that operators can rely on in real-time workflows.
  • Secure access, scalable protection: By integrating a programmable or keyed lock, the SP-KSM-3 adds a critical layer of security to control panels where access must be limited. This is especially valuable in environments with multiple operators or in scenarios where safety and asset protection are paramount. The keyed feature helps prevent tampering, accidental operation, and unauthorized use, preserving both personnel safety and system integrity.
  • Easy replacement and retrofit compatibility: The SP-KSM-3 is designed to be a straightforward replacement for the standard KS-3. Operators and technicians can upgrade without a complete panel redesign, preserving the existing footprint and mounting arrangements. This seamless retrofit capability reduces downtime, minimizes wiring changes, and allows for a quick transition to enhanced control with minimal disruption to production schedules.
  • Durability for demanding environments: Built to endure the rigors of daily use in industrial, stage, and machine-control settings, the SP-KSM-3 combines rugged construction with reliable actuation. The switch is engineered to withstand high-cycle operation, resist wear, and maintain consistent performance over time, contributing to lower maintenance costs and longer mean time between failures (MTBF).
  • Versatile control for single- or multi-station systems: The SP-KSM-3-Position Key Switch supports flexible control schemes, enabling it to function effectively in both single-station configurations and more complex multi-station networks. Whether you’re coordinating a single machine or synchronizing actions across multiple control points, the momentary Up/Down interface keeps operators in clear control, while the security of the key mechanism ensures systemic integrity.

how to install Draper SP-KSM-3-Position Key Switch

  • Power down the system and remove any existing KS-3 switch from the control panel, ensuring that the panel is safe and accessible for maintenance. Verify that the cutout dimensions, mounting hardware, and wiring conform to the SP-KSM-3 specifications to ensure a proper fit.
  • Prepare the SP-KSM-3 by inspecting the mounting surface and wiring terminals. If the panel uses a keyed lock, align the key slot to ensure smooth engagement and full rotation without obstruction. Confirm that the Up and Down actuators align with the panel’s front face for ergonomic operation.
  • Install the SP-KSM-3 into the panel cutout, securing it with the appropriate mounting hardware. Tighten mounting screws evenly to avoid distorting the faceplate, while keeping the switch firmly seated to prevent vibration or misalignment during operation.
  • Connect the wiring according to the panel’s schematic or the Draper installation guide. Ensure connections are clean, secure, and insulated to withstand operational conditions. Double-check that the wiring corresponds to the Up and Down circuits and that the key switch is wired to the control logic as intended for secure operation.
  • Reassemble the panel, restore power, and test the switch in a controlled sequence. With the key engaged, operate the Up and Down directions to verify that the momentary actuation reliably completes the intended circuit and that the return-to-neutral action resets smoothly after release. Conduct functional tests across all affected stations if used in a multi-station configuration.
  • Document the installation details for maintenance records, including the date of retrofit, any changes to wiring, and the observed switch behavior. This record will assist future servicing and help ensure continued reliability of the control system.

Frequently asked questions

  • What is the primary advantage of the SP-KSM-3-Position Key Switch? The primary advantage is combining secure, key-based access with precise momentary Up/Down control. This ensures that only authorized operators can issue directional commands while providing a clear, tactile interface for fast, reliable operation in busy environments.
  • Can the SP-KSM-3 replace a KS-3 in any Draper panel? The SP-KSM-3 is designed to replace the standard KS-3 in compatible Draper control panels. For a seamless retrofit, verify that the mechanical footprint, mounting, and electrical connections align with the existing KS-3 configuration. If unsure, consult Draper’s installation guidelines or a qualified technician.
  • Is the switch suitable for multi-station control? Yes. The SP-KSM-3 supports single- or multi-station configurations, enabling coordinated control across several points while maintaining individual security and directional control. This is particularly valuable in production lines and stage setups where synchronized actions are critical.
  • What does “momentary” mean in this context? Momentary action means the Up or Down circuit is completed only while the switch is actively pressed and the spring-loaded mechanism returns to its neutral position once released. This behavior helps prevent unintended movements and provides precise control timing.
  • What maintenance is required for the SP-KSM-3? The SP-KSM-3 is designed for durability and low maintenance. Periodic inspections to verify wiring integrity, mechanical smoothness, and keying operation are advised. If the panel is exposed to harsh environments, inspect seals and fastenings to ensure continued performance and security.

Good quality, bright, good light projection pattern, good choice for snowblowers
Color: 2Pcs 18W LED Flood Light, Color: 2Pcs 18W LED Flood Light
This review is ONLY for the Nilight model 1260LM (the package of TWO of them). This product has a flexible design, allowing it to be used in a variety of ways when you want to add illumination to a vehicle of some kind. It can be used as add-on fog lamps for trucks and off-road vehicle, it can be used as headlights for golf carts and such, and it is a good choice for adding headlights to snowblowers. The two mounting brackets allow swiveling and angling up and down for best aim and illumination pattern. Each 'lamp' assembly is mostly made of black anodized or black powder-coated aluminum, with a water-resistant design. The front 'lens' is Lexan or some other suitable clear plastic material with good, durable properties. The manufacturer claims that the included mounting hardware (bolts, nuts, washers) are stainless steel, but they seem to weigh too little to be SOLID stainless. Whatever they are made from, they do not attract strong (neodymium) magnets. Because I bought the lamps to use on my snowblower, I decided to replace the included hardware with solid stainless hardware. The large bolts for mounting the brackets are M8 x 1.25 and the smaller bolts for attaching the lamps to the brackets are M6 x 1.0. I also chose to purchase the smaller bolts with 'cap head' bolts, because it make lamp angle adjustment much quicker and easier. Each included bolt comes with a flat washer and a split-ring lockwasher, and the large bolts also come with nuts (the smaller bolts thread directly into pre-tapped holes in the lamp bodies). The included lockwashers make sense for the main mounting bracket bolts, but there is no reasonable place to use the lockwashers of the smaller bolts. I inquired of Nilight tech support, and they clearly had never thought about WHERE those lockwashers should be used, and they concluded that they probably should NOT actually be used. Each lamp has a short (perhaps 6") 'pigtail' cable coming out of one rear edge, and these cables each have a pair of wires inside; a RED one for + and a BLACK one for - . The user can wire these up any way that is desired, but probably they will be wired in parallel in most situations. I wish that the cables were longer; as it is, it is necessary to splice them to other cables in places that will not be hidden from view and/or otherwise protected from the elements. These lamps are designed to operate on 12VDC power, although the exact voltage is not critical. There is no need to use a special LED power supply, since the lamps include their own internal power conditioning circuitry. Powering these from 12VDC, EACH lamp will required 1A of current, to 2A total when wired in parallel. This comes to 12V x 2A = 24 Watts. In my case, I needed to power the lamps from a cordless power tool battery which produces a nominal 20VDC, which can drop as low as about 16V. Accordingly, I used one of the ubiquitous and inexpensive "DC Converters" (aka "DC-DC Converter") with an input having a voltage range that includes the expected 16~20V of the battery, and has a regulated 12V output, and has a Power (Watts) rating of at least twice the expected load, in this case a 60W one from Amazon. Since these converters have nearly a 100% efficiency, the input and output power (Watts) will be the same value, 24W. Doing the math in my case, an assuming an average battery voltage of 18V, the math is 24W / 18V = 1.3A. My battery has an Amp-Hour (Ah) of 4, so 4 / 1.3 = about 3 hours of operating time for the two lamps from a fully charged battery. My only gripes with the product have already been mentioned: - overly short power cords - poorly conceived hardware 'package'; the smaller lockwasher are useless, and the associated bolts should have had cap heads instead of hex heads (I won't complain about the lack of sold stainless steel hardware, since that would have driven the selling price WAY up)

Good bang for the buck.
Color: 2Pcs 18W LED Flood Light
I have bought 10 of these now. I put them on my work trailer and use them for reverse lights. They are cheap, easy to install, and they work very well. Now and then, I break one; they are exposed on my trailer and stuff happens, and these are so cheap it's not a big deal to replace them.

used for a snowblower light upgrade
Color: 2Pcs 18W LED Flood Light
I replaced the halogen bulb that came with my snowblower with these bad boys. Talk about a night and day difference! I was able to use two existing holes on the top of the blower and the included brackets to mount them. I also had to get a rectifier that converted the AC 24V to the 12V DC these expect. Used some scrap conduit, wire loom, and some project boxes to bring the whole thing together. Now the light is a lot brighter, and it's not half-blocked by the chute. Big improvement! You can find plenty of howtos and parts lists on youtube to do the same.

use care when starting the bolts.
Color: 2Pcs 18W LED Flood Light
Had these for awhile before I got around to installing them or should say attempted to install these. Mounting the bracket was challenging with supplied bolts. The predrilled holes in the mounting block were very poorly threaded. It was almost impossible to get the bolts started without cross threading. The finished product was acceptable. I have other Nilight products and never experienced a single issue.
