Micro-switches have become an important part of several industries, including agricultural, industrial, transportation, construction, and commercial. Globally, industrial machinery, agricultural or construction machinery, and control systems use billions of microswitches made by the best  micro switch supplier.  

These switches are simple and compact devices with two contacts. In different types of settings, these switches can operate reliably, safely and accurately. 

What is Micro Switch? 

With a very small contact gap, a micro switch is a snap-action precision changeover switch. The snap-action indicates a changeover switch. Here the speed of making contact and breaking it is independent of the actuator's operating speed. The following characteristics of micro switches make them different from regular switches: 

  • A smaller size. 

  • Tenths of a millimetre 

  • Operation travel is less 

  • Extended service life and improved electrical characteristics. 

  • Decreasing sensitivity to vibrations and high accelerations. 

When a physical touch of an object is permissible, microswitches are often the best choice for presence and absence detection. They perform well in programmes that only need basic on-and-off actions.  

With the help of a spring and a set of contacts, each switch transforms the mechanical force delivered to an actuator or plugger into an electrical output. You can buy this product from micro switch manufacturers who exclusively work on microswitches. 

How Does a Micro Switch Operate? 

Normally, the contacts move when the microswitch meets an object. The following is the working principle of switch: 

When you switch or depress the actuator; 

  • The circuit Normally Open (NO) will close 

  • The circuit Normally Closed (NC) will open 

When the actuator is released, or kept in rest position:  

  • The electricity is insulated by Normally Open circuit  

  • The current is carried by circuit that Normally Closes  
     

The micro-switches also have essential components, including the tipping-point mechanism. Surprisingly, the function helps in the production of specific trips (operating) and reset (releasing) places where contacts will change their state. 

 

Features of Micro Switches 

Microswitches have the following characteristics:  

  • It is a snap-action, precision changeover switch with a small contact gap. 

  • Logic-level and power-duty loads are well suited for this switch, which also has switch alternatives like SPDT, SPNO, or SPNC. 

  • Silver alloy contacts used for power duty switching 

  • Various types of electrical terminations. 

  • For logic-level control, connections are made of silver alloy or gold-plated. 

Terms used in MicroSwitches 

Other terms for the microswitch are listed below to help you understand its operation: 

  1. Reset or Release Point 

The switch contacts return to their original position at this stage.  

 

  1. Differential Travel 

This phrase defines the area between the operating point and the releasing point. To protect the contacts from sudden and unpleasant ON/OFF, these two points are separated. This also occurs when vibration tries to reduce the switch's working life. 

 

  1. Operating or Trip Point 

The place when contacts depart from their unoperated position, then their initial state, is known as the trip point. 

  1. Over-Travel 

The micro switch contains this safety feature, and it helps prevent switch damage. This happens by allowing the plunger to move past its functioning positions. 

You also need to make sure the plunger doesn't move beyond than required distance. So, it will aid in lowering damage and mechanical stress.
