Model: KW12B — 1PCS 3Pin Handle Microswitch, 16mm Stroke, Silver, 5A/250V Why choose this switch Compact, reliable mechanical switching for position detection and control. The KW12B delivers consistent on/off action with a clear 16mm actuator travel, making it suitable for many and DIY applications. Rated for 5A at 250V AC, it handles common mainslevel loads used in small appliances and control circuits without excessive bulk. The threepin design (COM / NO / NC) provides flexible wiring options for normallyopen, normallyclosed, or changeover configurations. Key features and benefits Model: KW12B — matches original specification for direct replacements and upgrades. 3pin configuration: standard COM, NO, NC terminals for straightforward integration into existing circuits. 16mm stroke: predictable actuator travel for precise limit or position sensing. Silver finish/contacts: offers good electrical conductivity and visible condition for inspection. Electrical rating: 5A / 250V AC — suitable for many household and light industrial uses. Handle actuator: easy to operate by hand or by mechanical linkages; suitable where a small lever or handle is required. Compact form factor: fits into tight spaces and enclosures where space is limited. Performance and compatibility Functions as a microswitch for detecting movement or acting as a limit switch in control systems. Compatible with common wiring practices thanks to the threeterminal layout (COM/NO/NC). Intended for low to moderatecurrent applications within the 5A/250V rating — use appropriate fusing and wiring for safety. Typical applications (use cases) Appliance : worn or damaged door or control switches in small appliances where a compact, rated microswitch is required. Position or limit detection: use as a mechanical endstop or limit sensor in small machines, conveyors, or hobby automation projects. DIY electronics and prototyping: convenient for custom control panels, enclosures, or projects that require a durable manual/actuated switch. Installation and handling tips Verify wiring before applying power: identify COM, NO, and NC terminals to wire the desired circuit behavior. Use appropriate connectors or soldering techniques compatible with the switch terminal style — avoid excessive heat when soldering. Respect the 5A/250V rating — for loads above this rating use a relay or higherrated switch. Mount securely to avoid mechanical stress on the terminals or actuator. What's included 1 x KW12B 3pin handle microswitch (silver, 16mm stroke, 5A/250V) This KW12B microswitch is a practical, specificationmatching component for repairs, upgrades, and small control systems where a compact, threeterminal mechanical switch is required.
