Questions about this product
- What are these micro limit switches actually used for?
- They sense position or trigger an action when something presses the actuator. The snap-action SPDT contacts give you both Normally Open and Normally Closed in one switch. People use them for end-stops, door sensing, and small control logic on 3D printers, robots, and PCB projects.
- How much voltage and current can these switches handle?
- Each switch is rated for 1A at 125V AC, so they suit low-power control circuits only. Don't run motors, heaters, or mains loads directly through them. For anything heavier, use the switch to drive a relay or transistor instead.
- What comes in the 20-piece kit and which actuators do I get?
- You get 20 micro switches with a mix of actuator styles in the set. The kit includes roller lever, arc lever, and push-button types so you can match different triggering setups. Each switch has 3 PCB pins: common, NO, and NC.
