RS PRO SPDT Lever Subminiature Microswitch

The precision snaps action for on/off applications is a synonym of Microswitch.

Today, we are proudly introducing our own branded RS PRO Miniature Micro Switch where current mechanical energy applied to an actuator provides a high-precision electrical output.

The actuator type comes as a basic switch with unfitted actuator kit and fining hardware, offering you an impressive temperature operating range of -54°C up to +121°C allowing you full application flexibility.

Features and Benefits

  • The Switch provides high switching current

  • Where the space is prime, our ultra SPDT Microswitch is here to eliminate the issue

  • As a standard, our contact material is silver-plated

  • Contact rating: 7 A (resistive), 4 A (inductive), 250 V ac, 28 V dc

  • High-precision, presence/absence detection terminal

  • Ultra Subminiature and lightweight

  • Long operating life

Applications

Microswitch fits perfectly with:

  • Appliances

  • Computer/business equipment

  • Communication equipment

  • HVAC (Heating, Ventilation, and Air Conditioning)

  • Manually operated devices

  • Medical, Dental equipment

  • Office equipment

  • Test instruments and timing devices

  • Valves and vending machines

  • Door interlocks

  • Microwave ovens

  • Elevators

Frequently asked questions

What are microswitches?

Microswitches are mechanically operated electrical switches designed with an actuator and terminals called common, normally open and normally closed. A microswitch is also known as a snap action switch; they operate by using a spring-loaded lever to open and close a set of internal contacts inside the unit.

How does a microswitch work?

Power is typically attached to the common terminal; this leads into the Switch and energises the spring and because the spring is touching the normally close pin it sends power out here, this is called a resting state. Once the arm is moved, the power is then transferred to the normally open pin.
