Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch structure for avoiding wiring short circuits. Background Art

[0002] A push button switch is a simple switch mechanism, which is mainly used to switch the working state of a circuit. Push button switches are widely used in some factory processing equipment, mainly used to control the start and stop of machines or certain motion processes. Push button switches in the prior art are divided into normally closed mode and normally open mode according to different wiring. The circuit with a button in the normally closed mode is always in the on state before working, and the circuit is disconnected when the button is pressed; on the contrary, the circuit with a button in the normally open mode is always in the off state before working, and the circuit is connected when the button is pressed.

[0003] For example, the Chinese invention provides "a push button switch that is easily adjustable", with the announcement number: CN115274333A. The application includes a shell, connecting terminals arranged at both ends of the shell, a mounting port arranged on the shell and a button movably installed in the mounting port; a conductive sheet is arranged inside the shell; a turntable is rotatably installed on the inner side wall of the shell, and a conductive contact is arranged on the turntable, and electrical connection is achieved between the conductive contact and the connecting terminal on the same side; the initial state of the push button switch in the normally closed mode is that the conductive contact is at the top position and contacts with the conductive sheet; the initial state of the push button switch in the normally open mode is that the conductive contact is at the bottom position and is out of contact with the conductive sheet; when the button is pressed by external force, the conductive sheet that moves downward contacts with the conductive contact, thereby, the present invention can drive the conductive contact to switch the state by rotating the adjusting sleeve, thereby realizing the switching of the push button switch between the normally closed mode and the normally open mode, and realizing rapid adjustment between modes.

[0004] Although the push button switch in the above technology can achieve rapid adjustment between modes, due to the lack of good protection around the connection terminals, the connection terminals and the connected wires are prone to short circuits due to dust adhesion or water vapor during long-term use, which has an adverse effect on the overall normal operation.
