Reliable, compact momentary switches designed for practical control and reset applications. These 10 pieces of KW11N / KW12 hinge roller lever tact switches give you a flexible SPDT contact arrangement with a sturdy roller lever for positive actuation from different angles. Key benefits Versatile switching: SPDT (single pole, double throw) with 1NO (normally open) and 1NC (normally closed) contacts lets you use the same switch for makeorbreak control without extra wiring. Suitable for moderate loads: Rated 5A at 125/250V, providing dependable switching for many control, appliance, and industrial applications. Positive actuation and repeatability: Momentary action returns to the default position when released; the hinge roller lever provides mechanical advantage and smoother actuation where linear contact is intermittent. Readytoinstall pack: Supplied as 10 pieces for projects, repairs, or small production runs. Key attributes Quantity: 10 pieces Models: KW11N, KW12 Contact arrangement: SPDT (1NO, 1NC) Action: Momentary (spring) Actuator: Hinge roller lever Pins: 3 pins for straightforward wiring or connector integration Electrical rating: 5A at 125/250V Practical applications Machine control and limit sensing: Use the roller lever to detect part position or act as a compact limit switch on moving assemblies. Reset or safety interlock buttons: Suitable for reset functions where a momentary action and clear NO/NC signals are required. DIY electronics, appliances, and panel controls: Compact 3pin layout and SPDT contacts make these switches useful for control panels, hobby projects, or replacing worn tact switches. Installation and use tips Verify compatibility with your circuit voltage and current; the switches are rated 5A at 125/250V. Use appropriate wiring and secure mounting to prevent mechanical stress on the pins. Test switch action and contact continuity before final assembly to confirm wiring and function. Compact, functional, and supplied in a convenient 10piece set, these KW11N / KW12 hinge roller lever momentary tact switches provide a practical solution when you need reliable momentary SPDT switching with both NO and NC outputs.
