Description

Technical Field

[0001] The present application relates to the technical field of electrical automation equipment, and in particular to an electrical automation switch with an anti-static structure. Background Art

[0002] A switch is an electronic component that can open a circuit, interrupt current, or make it flow to other circuits. Switches are widely used and are often used in the power field. Existing power switches generally only have live and neutral connectors, and their anti-static ability is very weak. In the dry environment with high static electricity in winter, it is easy to cause damage to electrical appliances and even cause electrical safety hazards.

[0003] At present, a Chinese patent announcement with announcement number CN217214549U discloses an electrical automation switch with anti-static function, which relates to the field of electrical engineering technology and includes a controller, a housing, a card case and a torsion piece. The front end outer side of the controller is fixedly carded with the rear end inner side of the housing and the card case, and the front end of the controller is movably plugged with the rear end inner side of the torsion piece. A cleaning piece is fixedly installed at the front end of the card case, and the inner side of the cleaning piece is movably installed with the outer side of the torsion piece. This enables the torsion piece to quickly adjust the circuit opening and closing state through the controller, and when the user twists the torsion piece, the outer side of the torsion piece keeps in close contact with the wiping strip on the inner side of the cleaning piece, so that the hand sweat bonded to the outer side of the rotating torsion piece is quickly rubbed and cleaned by the wiping strip, avoiding the problem that the salt in the hand sweat accumulates on the outer side of the torsion piece and reduces the insulation performance of the switch.

[0004] In actual use, it is found that the wiper strip in the existing device cannot be disassembled and assembled, and a large amount of stains will remain after long-term use of the wiper strip. If it is not cleaned or replaced in time, the cleaning effect of the rotary knob will be reduced, thereby affecting the insulation performance of the switch. Therefore, we propose an electrical automation switch with an anti-static structure to solve the above problem. Utility Model Content
