The safety microswitch is a mechanical switch with a tiny contact, its role is to be used as a switch in the circuit, can control the circuit on and off.


1, control circuit on and off:
The most basic function of the instantaneous microswitch is to control the on-off of the circuit. In the circuit, the micro switch can be connected to two circuit nodes, when the micro switch is pressed, the circuit between the two nodes will be connected, so that the current can flow; When the lever microswitch is released, the circuit between the two nodes is disconnected and current cannot flow. This control method is widely used in various electrical equipment, such as lights, televisions, computers and so on.


2, detect the location of the object:
High-quality microswitches can also be used to detect the position of objects. When the object moves to the position of the microswitch, the control microswitch converts the change in the position of the object into the action of the contact through the mechanical mechanism, thus controlling the on-off of the circuit. This detection method is widely used in automatic control systems, such as robots, automated production lines and so on.
3, to achieve precision control:
Precision control is possible thanks to the high quality manufactured microswitches with tiny contacts. In cases where high-precision control is required, such as precision instruments, medical devices, etc., microswitches can ensure the stability and accuracy of the equipment.

4, protect electrical equipment:
In some electrical equipment, microswitches can also play a protective role. For example, in the motor, when the motor is overloaded or short circuit, the micro switch can quickly cut off the power supply and protect the motor from damage. In summary, the microswitch has a variety of functions in the circuit, which can control the on-off of the circuit, detect the position of the object, achieve precision control and protect electrical equipment. Because of its small size, easy operation, stable performance and other advantages, microswitches are widely used in modern industry, electrical appliances and other fields. ​
