Product Description

3 Pin Micro Limit Switch SPDT 1NC+1NO AC 1A 125V CYT1073

= Reliable Snap-Action Switch for Arduino and Mouse Projects =

This miniature 3-pin SPDT (Single Pole Double Throw) micro switch provides versatile control with both Normally Open (NO) and Normally Closed (NC) contacts . Its long hinge lever offers precise momentary actuation for Arduino projects, mouse repairs, and automation systems.

Long Hinge Lever Design - Provides easy mechanical actuation in compact spaces
SPDT Contact Configuration - Offers both NO and NC wiring options
Rated for AC 1A at 125V suitable for lowpower switching applications
For mouse replacements, check original switch dimensions before installing

= Connection and Usage Guide =

The CYT1073 functions as a momentary switch with three terminals . The common pin and the two switch contacts allow you to choose between NO and NC configurations.

For a normally open circuit, connect the common and the NO pin
For a normally closed circuit, connect the common and the NC pin
Do not exceed the 1A current rating - use a relay for higher loads

= Troubleshooting =

Switch not triggering:

  • Check wiring connections to the correct NO/NC and common pins
  • Verify the lever arm is being fully depressed
  • Avoid over-tightening mounting screws which can bind the mechanism

Intermittent actuation:

  • Ensure clean, debris-free contact surface
  • Check for loose connections
  • Consider replacing after lifespan
