🔍 Technical Insight – How a Micro Switch Works

A micro switch uses a spring-loaded actuator to move internal contacts between open and closed states.
When pressed, it produces a distinct click that confirms activation.
Because of their snap-action mechanism, micro switches ensure fast and reliable signal transition with minimal bounce, even under repetitive use.

🌍 Typical Applications

HVAC systems and thermostats
Door interlocks, security alarms, elevator panels
Medical foot and hand controls
Automotive seatbelt sensors and door actuators
Appliance controls – rice cookers, microwave ovens, refrigerators
Industrial joysticks and control panels
CCTV and alarm trigger devices

🔒 Waterproof and Ruggedized Options

For outdoor, industrial, or medical applications where moisture and dust are a concern, IP67-sealed micro switches provide complete protection against water ingress.
They are particularly suited for medical pedals, industrial joysticks, and outdoor machinery controls.

🧠 Knowledge Corner

What makes a micro switch different?
Its precision snap-action mechanism guarantees reliable switching with minimal mechanical wear.
Why choose IP67?
Because it allows use in wash-down environments, humid conditions, or outdoor systems.
How long do they last?
Most models are rated for millions of actuations, ensuring exceptional longevity.
