Micro Limit Switch – SPDT 3-Pin | 1A 125V | Multiple Actuator Styles

Upgrade your electronics, robotics, or automation projects with this compact and reliable Micro Limit Switch. Rated at 1A / 125V and featuring a Single Pole Double Throw (SPDT) configuration with 3 pins, this momentary push button switch delivers precise, snap-action switching in a small footprint — perfect for tight spaces and sensitive applications.

Available in three actuator configurations to suit your project needs:

  • Without Handle – Bare button actuator for direct mechanical contact
  • With Handle – Extended lever for easier triggering over a wider range of motion
  • With Roller Handle – Roller-tipped lever for smooth, low-friction actuation, ideal for moving parts and conveyors

Frequently Asked Questions

Q: What is the difference between the three micro limit switch variants?

A: The Without Handle version has a bare button actuator for direct contact. The With Handle version includes an extended lever that allows actuation over a wider arc of motion. The With Roller Handle version features a roller-tipped lever that reduces friction and wear, making it ideal for moving or sliding components such as conveyor belts or 3D printer axes.

Q: Is this micro limit switch suitable for a 3D printer end-stop?

A: Yes! This SPDT 3-pin micro switch is one of the most popular choices for 3D printer end-stops and CNC homing switches. Its compact size, snap-action response, and normally open/normally closed terminals make it straightforward to wire into any control board.

Q: What does SPDT mean and which pins should I use?

A: SPDT stands for Single Pole Double Throw. The switch has three pins: COM (Common), NO (Normally Open), and NC (Normally Closed). Use COM + NO for a circuit that closes when the button is pressed, or COM + NC for a circuit that opens when the button is pressed.

Q: What is the operating voltage and current rating?

A: This micro limit switch is rated at 1A at 125V AC. It falls under the EU Low Voltage Directive classification (below 50V AC or 75V DC for low-voltage use), making it suitable for a wide range of signal and low-power switching applications.
