wall control switch

Abstract

The invention discloses a wall control switch. The wall control switch is characterized in that a lower insulating eccentric plate is fixed onto two inner walls of the lower portion of an insulating shell, a bump is arranged at one end of the lower insulating eccentric plate, the middle of the lower end of one side of the lower insulating eccentric plate is connected with one end of a return spring of the lower insulating eccentric plate, the other end of the return spring of the lower insulating eccentric plate is fixed onto the insulating shell, and the lower insulating eccentric plate carries out power-on and power-off operation via a lock, an electromagnetic sensor, a movable armature, an upper insulating eccentric plate, return springs, a starting ejector rod, a power-off ejector rod and the like. The wall control switch with the structure has the advantages that an electric device or a circuit can be automatically powered off under conditions such as fire, overcurrent, poor contact or excessively high voltage, and potential safety hazards of a switch circuit are reduced.

Description

technical field [0001] The invention relates to a switch, in particular to a wall control switch. Background technique [0002] Although there are many types of existing wall switches and beautiful styles, but because the existing wall switches have no effective protection function except for power-on and power-off functions, they will not automatically cut off the power when the electrical appliance encounters a fire or over-current, and even burns Electrical appliances can cause fires if they are heavy, and cannot effectively protect people's safety. Contents of the invention [0003] Aiming at the deficiencies of the existing devices, the purpose of the present invention is to provide a wall control switch that can automatically cut off the power when the current is overcurrent or touches a fire. [0004] The object of the present invention is achieved in that it fixes the lower insulating eccentric plate with a protrusion at one end on the two inner walls of the lower...
