Electric-shock-proof control switch

Abstract

The invention relates to an electric shock prevention control switch, include metal bumps, housing indicating identification, switch knob, Switch retainer, Sealing cover, center projection, connectinggroove, connecting projection, connecting rod, Rotary shank, sheet metal, rotary shank protrusion, lumen, knob piercing, fixing groove, Connecting holes, fixing projections, compression groove, rotary shank through slot, Fixing tabs, junction boxes, positioning post, Protective cover, threading hole, the terminal bump touches the conductive groove, At one end of that shell, a central convex contact is centrally arrange, Central projection penetrate that lumen, A connecting hole is arranged at the center of the central convex contact in the inner cavity, seven metal convex contacts are arranged at equal intervals around the central convex contact, an indication mark is arranged at the other end of the shell, and the indication mark corresponds to the position of the metal convex contact, and an inner cavity is arranged inside the shell. The anti-electric shock control switch designed by the invention has the advantages of simple operation, accurate control, safety and reliability.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electric shock prevention control switch. Background technique [0002] A switch refers to an electronic component that can open a circuit, interrupt the current, or allow it to flow to other circuits. The principle of the switch is that the "closed" of the contact means that the electronic contact is turned on and allows the current to flow; "open circuit" means that the electronic contact does not Conduction forms an open circuit and does not allow current to flow. According to the application, it is divided into fluctuation switch, band switch, recording and playback switch, power switch, preselection switch, limit switch, etc. According to the structure, it is divided into micro switch, ship type switch, button switch, Toggle switches, etc. However, most of the current control switches are in one-to-one control mode, and the operation is complicated, the insulation is ...
