Micro Switches Why you need these micro switches Reliable, repeatable switching for control and safety: precise snapaction operation ensures fast, definite contact change that prevents contact arcing and reduces false triggers. Compact solution for spaceconstrained designs: small footprint and multiple mounting options make them easy to integrate into panels, PCBs, or mechanical assemblies. Long service life and predictable performance: designed for cycle counts so devices stay operational longer with less maintenance. Key benefits at a glance Precision operation: snapaction mechanism gives consistent actuation force and travel for predictable switching behavior. Versatile compatibility: suited for appliances, industrial controls, HVAC, automotive applications, consumer electronics, and hobby projects such as 3D printers. Multiple actuation styles: available with straight plungers, roller levers, short or long actuators to match mechanical interface needs. Flexible mounting and termination: PCB pins, solder terminals, quickdisconnect tabs, and screw terminals available to fit common installation methods. Durable construction: rugged plastic housings with metal contacts for electrical reliability and mechanical strength. Configurable electrical ratings: offered in common voltage and current ratings so you can select the switch that matches your circuit requirements. Function, size, material, and performance Function: standard snapaction micro switches perform momentary on/off or limit sensing; common contact arrangements include SPDT and DPDT for simple changeover or dualcircuit control. Size: compact enclosures minimize panel space and are suitable for tight assemblies; actuator lengths and lever types adapt to different mechanical interfaces. Material: housings made from flameretardant thermoplastic; internal contacts typically silverplated or similar conductive materials to reduce contact wear and resistance. Performance: engineered for mechanical and electrical lifetimes, with consistent actuation force and defined travel distances for repeatable operation. Available in various rated voltages and currents to match lowpower to moderateload circuits. Practical applications (realworld scenarios) Appliance door interlock: use a rollerlever micro switch to detect door position on a washing machine or dryer, reliably shutting off power when the door opens. Limit sensing in equipment: integrate a plunger micro switch in conveyor or robotics endoftravel assemblies to stop motors at precise positions. User input and safety cutoffs: employ PCBmounted micro switches in control panels, joysticks, or emergency stop mechanisms where a small, dependable switch is needed. Installation and selection tips Match electrical rating to your circuit: choose a switch with appropriate voltage and current ratings and consider contact material for lowvoltage, lowcurrent signals versus higherload applications. Pick the right actuator: rollers and levers reduce wear when interacting with cams; plungers suit direct linear contact. Choose the proper termination: select PCB pins for boardmounting, spade terminals for quick wiring, or screw terminals for robust field connections. Consider operating force and travel: select switches with actuation force and differential appropriate to your mechanism to avoid accidental triggers or failures to actuate. Why these micro switches stand out Predictable, repeatable performance for control and safety tasks. Multiple mechanical and electrical options to fit diverse applications without redesigning the host product. Designed for straightforward replacement and field service, reducing downtime. Ordering/availability notes Available in several actuator styles, contact configurations (SPDT/DPDT), mounting options, and common electrical ratings. Specify actuator type and termination when ordering to ensure compatibility with your application. Contact or reference your supplier for detailed datasheets, electrical ratings, and mechanical dimensions to confirm the exact model meets your technical requirements.
