First, the principle of micro switch
A microswitch is a mechatronics electronic component that opens and closes the switch contact through mechanical force to control the switch of a circuit or mechanical device. The basic components of microswitch include contact, fixed frame, shrapnel, moving contact plate, guide rod, etc.
The internal microswitch is usually composed of a group of electrical contacts and elastic structure, when the external force acts on the movable component of the microswitch, by passing to the elastic structure, the microswitch converts the contact state, and realizes the switching control of the circuit or mechanical equipment. If the external force disappears, the contact of the microswitch returns to its original state.
Second, micro switch function
Microswitches are mainly used in some circuits or mechanical equipment that need to control the switching state and start-stop action, and have the following functions:
1. Control circuit switch: Micro switch can control the switching state of the circuit through mechanical force to achieve the start, stop, reverse and other control functions of electrical equipment.
2. Control mechanical equipment: Microswitches can control the start and stop, position, direction and other control functions of mechanical equipment through mechanical force, and are often used in automated production lines and other occasions.
3. Avoid misoperation: The micro switch can sense the size and direction of the external mechanical force to avoid misoperation and mistriggering, and improve the stability and reliability of the equipment.
