Micro Limit Switch 3pins 2A 125V 13mm

The Micro Limit Switch is a small snap-action switch with three pins, rated 2 A at 125 V and 13 mm in size. It changes state with a light press on its actuator, giving a clear click and a reliable signal, so it is widely used as an endstop in 3D printers and CNC machines and as a bumper or door sensor in robotics.

Micro Limit Switch Specifications

• Type: micro snap-action limit switch

Micro Limit Switch Applications

• Endstops for 3D printers and CNC machines
• Home position detection on robot arms and linear rails
• Bumper sensors on robot cars
• Door, lid and safety interlock detection
• Arduino button and position input projects

What's in the Box

• 1 × micro limit switch, 3 pins

Tip: For a normally open input, wire COM and NO; for normally closed, use COM and NC, which also lets you detect a broken wire. On an Arduino, connect COM to GND and the other pin to an input set to INPUT_PULLUP.
