Electric appliance switch capable of preventing electric shock

Abstract

The invention discloses an electric appliance switch capable of preventing electric shock. The electric appliance switch comprises a base, wherein the top end of the base is provided with a first groove, the first groove is internally connected with a switch blade in a sliding manner, the top end of the switch blade is perpendicularly connected with an insulation plate, one end, away from the switch blade, of the insulation plate is vertically connected with a first push plate in a welding manner, the top end of the base is connected with a protection box, two side walls of the protection boxare respectively provided with a first channel along a length direction, the top end of the protection box is provided with a second channel along the length direction, the interior of the first channel is communicated with the interior of the second channel, the first push plate is separately connected with the first channel and the second channel in a sliding manner, two side walls of the bottomend of the first channel are provided with a second groove, one side wall of the second groove is connected with a stretchable rod, the other end of the stretchable rod is connected with a limiting plate in a welding manner, and the limiting plate is perpendicular to the stretchable rod. By adopting the electric appliance switch, a blade switch can be rapidly turned off and turned on, the electric shock situation can be prevented, and the switch blade position can be fixed, so that the loosening of the switch blade in the application can be prevented.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to an electrical switch for preventing electric shock. Background technique [0002] Switching appliances refer to switches used in low-voltage electrical appliances for infrequently manually switching on and off circuits, or as switches for introducing power in machine tool circuits. They are divided into knife switches, combination switches, etc., and are used in electrical control equipment in industrial and mining enterprises. [0003] During the use of the knife switch, when the knife is pushed, the finger is easy to touch the knife, which will cause electric shock to the personnel and cause life danger. Moreover, the traditional knife switch controls the opening and closing of the circuit by pushing the knife. The knife is prone to loosening in its original position, which makes the circuit voltage and current prone to jump. For this reason, we propose an electrica...
