Micro Switches Overview

Micro switches (also called snap-action switches or mini switches) are compact electromechanical devices that deliver reliable switching action through a spring-loaded mechanism. Despite their small size, micro switches handle significant electrical loads and provide long mechanical life.

Compact Design

High switching capability in minimal space

Snap-Action

Reliable contact movement with consistent performance

Long Life

Mechanical life up to 1,000,000 cycles

Product Types

Standard Micro Switches

General-purpose micro switches for common applications. Available in multiple actuation forces, terminal styles, and mounting configurations.
