How Micro Switch Works

Een microschakelaar, also known as a miniature snap-action switch, is a type of momentary contact switch used widely in automotive, industrial, and medical instruments as a sensor.

Waterproof Micro Switch Meaning

The switch is termed “micro” on the company’s name that first started manufacturing it commercially. The actuator of these switches often has a hinged wheel placed above a push button. This switch is widely used in control system applications such as door interlocks, safety switches in elevators, vending machines, enzovoort.

Having a diverse range of engineering applications, micro switches are available in various switch configurations, housing materials, actuator styles, enzovoort. But what makes these switches be called “snap action” switches? How does the switch manage the momentary contact? Does a combination of spring or thin plastic fibres allow such motion?

Continue reading to reveal all the answers. A conventional SPDT micro switch is a blunt-edged rectangular structure with three output contact strips denoting common (ground), open and closed states. Two diagonally opposite holes are dug in to provide easy mounting of the switch on the surface.

Op dezelfde manier, holes at the terminals of output contact strips allow easy soldering with the wires. The plastic box can be made of polyester or phenolic plastic products.
