Application For Micro Switch

Car seat switch and glass lift switch are also widely used to the micro switch,the following seat switch seat switch can be seen that the circuit is relatively simple, should be directly connected to the seat motor, the switch used to 3 micro switch, through the micro switch direct conduction or cut off the power supply. Micro switch mainly includes drive rod, movable plate, static contact. Drive bar: The part of the switch that conducts the force from the outside to the internal shrapnel structure to push the moving contact for switching action. Movable plate: refers to the part of the mechanism that switches the contact, sometimes called a movable spring. The movable piece contains moving contacts. The high-current switching contacts are generally silver alloy, and silver tin oxide contacts are commonly used. They have good resistance to electric wear, fusion welding and electrical conductivity, and small and stable contact resistance. Contact interval: It is the interval between static contact and moving contact, and the effective distance of switch. The same general glass lift switch each function also corresponds to a micro switch, the principle is the same, there are movable pieces, contact interval, etc. In summary, the micro switch is the force applied to the movable piece by the external force through the driving part (press the pin, the driving rod, etc.). When the movable piece is moved to the critical point, the instantaneous action will be generated, so that the moving contact and the static contact at the end of the movable piece can be quickly connected or disconnected. When the force on the driving part is removed, the movable piece produces reverse action force. When the reverse travel of the driving complement reaches the critical point of the movable piece's action, the reverse action is instantaneously completed.
