When force reaches a critical threshold, the internal reed springs into action — making or breaking the circuit almost instantaneously. When the force is released, the reed reverses direction just as quickly. The result is a fast, clean switch operation with minimal travel distance and low actuation force required.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCompact snap-action SPDT design for quick, reliable switching\u003c\/li\u003e\n  \u003cli\u003eSmall contact spacing and short stroke action for precision control\u003c\/li\u003e\n  \u003cli\u003eRoller lever arm allows smooth, consistent actuation\u003c\/li\u003e\n  \u003cli\u003eNormally Open (NO) and Normally Closed (NC) terminals included\u003c\/li\u003e\n  \u003cli\u003eSuitable for PCB \/ circuit board mounting\u003c\/li\u003e\n  \u003cli\u003ePack of 10 — great value for prototyping and repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWide Range of Applications\u003c\/h3\u003e\n\u003cp\u003eThese versatile micro limit switches are used in a broad array of applications, including:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComputer mouse and peripheral devices\u003c\/li\u003e\n  \u003cli\u003eAutomotive electronics\u003c\/li\u003e\n  \u003cli\u003eCommunications equipment\u003c\/li\u003e\n  \u003cli\u003eTest instruments\u003c\/li\u003e\n  \u003cli\u003eGas water heaters and gas burners\u003c\/li\u003e\n  \u003cli\u003eSmall home appliances, microwave ovens, and electric rice cookers\u003c\/li\u003e\n  \u003cli\u003eFloating ball support equipment\u003c\/li\u003e\n  \u003cli\u003eMedical equipment\u003c\/li\u003e\n  \u003cli\u003eBuilding automation systems\u003c\/li\u003e\n  \u003cli\u003ePower tools and electric tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e10 × KW12-3 Micro Roller Lever Arm Normally Open\/Close Limit Switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.osha.gov\/personal-protective-equipment\" target=\"_blank\" rel=\"noopener\"\u003eOSHA on personal protective equipment\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What does SPDT mean on these micro limit switches?\u003c\/h4\u003e\n\u003cp\u003eA: SPDT stands for Single Pole Double Throw. This means each KW12-3 micro limit switch has one common terminal plus two output terminals — one for Normally Open (NO) and one for Normally Closed (NC) connections — giving you flexibility in how you wire them into your circuit.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these micro limit switches compatible with PCB mounting?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The KW12-3 mini micro limit switches feature PCB terminals, making them easy to solder directly onto a circuit board. Their compact 20 × 10 × 6 mm footprint makes them ideal for space-constrained electronics projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage and current can these snap action switches handle?\u003c\/h4\u003e\n\u003cp\u003eA: Each switch is rated for AC 125V–250V and up to 5A current. They also comply with EU LVD low-voltage directives (below 50V AC or 75V DC), making them suitable for a wide range of household and industrial electronics applications.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
