Micro Switch Manufacturing, Features & Working Principle

micro switch

We are a micro switch manufacturer in the Zing Ear group with more than 30 years of experience since 1983 from Taiwan, the technology was from Japan. Meanwhile, we require our production system strictly and the microswitch also performs well.

The Micro Switch Features

The micro switch also calls a microswitch or snap action switch, controls on-off for the home appliance in SPST, SPDT contact, with different terminals and levels for customized services. In order to fit different equipment and appliances, the switches as a part are designed in different sizes, different shapes, and different functions. Such as subminiature, mini, large size, waterproof and non-waterproof function, and so on. Zing ear brand is a perennial experience of microswitch supplier since 1983, are your reliable partner and switch counselor in China. Our switch can replace Omron, Cherry, Honeywell, Hartmann, Logitech, etc. Such as item V3-1, z15g1701, dc1 6a250, d2fc f 7n, VMN 15 15a, 83170.0, hk 14, crouzet 83181, and so on.

Micro Switch Working Principle

The external mechanical force acts on the leaf spring through the transmission elements, such as press pins, buttons, levers, rollers, etc. When the leaf spring is displaced to the critical point, then the end of the spring leaf and the fixed contact point will turn on or off quickly. And, when the force on the transmission element is removed, the spring leaf produces a reverse action force to push it back. Then the reverse action is complete.

As a professional factory, we can provide many micro switch types, such as protection type (waterproof, dustproof, explosion proof ), circuit code type (DPDT, SPDT, SPST-NO, SPST-NC), the size type (big, medium, large), etc.

How to wire a micro switch diagram?

Generally, the micro switch will be used to control the electrical system. And the article is suitable for anyone who is not very experienced with electronics and wants to know how to wire a micro switch. Like household appliances repairing, company buyer, physical tests,s and so on.
Firstly, wiring a micro switch needs to understand of its circuit diagram. Generally, the micro switch manufacturer will give you a drawing or datasheet for your reference.

If not, we also can recognize it from a switch appearance. But before that, you need to understand what the COM, NO, NC terminal is. For example, you can know from the illustration to see what they are.

The Application for Snap Action Switch

It has been widely in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, tanks, and other military fields. Although the switch is a small part of the machinery, it really plays a very important role in the system.

Usually, the different applications have different requirements for the switch. For example, the mechanical life is from 30000 to 10000000 cycles which can fit different applications.

Such as a computer mouse, car mice, automotive electronic products, communication equipment, military products, testing equipment, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, medical equipment, building automation, electric Tools and general electrical and radio equipment, 24-hour timers, etc.
