Micro Limit Switch 3pins 1A 125V

The Micro Limit Switch is a small snap-action switch with 3 pins and a contact rating of 1 A at 125 V. When its actuator is pressed, the contacts change over with a quick, defined click, giving a reliable signal for end positions in 3D printers, CNC machines, robots and automation projects. The three pins give you both normally open and normally closed connections.

• Position detection in automation projects

What's in the Box

• 1 × micro limit switch, 3 pins

Tip: For an Arduino endstop, connect COM to GND and NC or NO to an input pin with INPUT_PULLUP. Using NC is often preferred, because a broken wire then reads as triggered and the machine stops safely. Stay within 1 A: to switch motors or mains loads, let the switch control a relay instead.
