Abstract

The invention discloses a self-locking switch for pulling out a press plate, which comprises a press plate button, a shell, a base, a moveable base, a moving piece, a bracket and a spring. The upper part of the moveable base is connected with the press plate button, the lower part of the moveable base is connected with the spring, and the head of the spring is connected with the moveable piece. The spring is internally provided with a spring core. The bracket is arranged in the lower part of the moveable piece and the bracket is U-shaped. Both ends of the moveable piece are provided with a first contact and a second contact. The bracket is riveted on the base through copper rivets. The press plate button is connected with the shell through a pin roll. According to the self-locking switch for pulling out the press plate, provided by the invention, the press plate button is uplifted to open and close the switch, so that the self-locking switch for pulling out the press plate provided by the invention is reliable in work performance. The moveable contact working part is pulled and magnetically closed in an R-shaped arc-shape so that the self-locking switch for pulling out the press plate has the advantages of dust prevention, moist prevention, good arc extinguishing performance, small volume and the like, and is suitable for being used as a shutdown switch of a motor operating at a high speed.

Description

Technical field [0001] The invention relates to a self-locking switch, in particular to a self-locking switch with a pressure plate pulled out. Background technique [0002] At present, in industrial production, the production of double-track jig saws, desktop cutting machines, miter saws, and rotary cutting machines are widely used, but the original machine is equipped with a straight handle push switch, which is easy to operate in a strong vibration working environment. The saw blade is broken and stuck, which is prone to safety accidents. Summary of the invention [0003] Objective of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a self-locking switch with a pressing plate pulled out, and the switch is turned on and off by rotating the pressing plate button around the pin shaft, and has good safety performance. [0004] Technical solution: In order to achieve the above objective, a pressure plate pull-out self-locking switc...
