According to the button switch, the button switch can be matched with a split type switch when the button switch uses the buckle type middle seat, and the problem that the use cost is relatively high due to the fact that the whole switch needs to be replaced when one of the normally-open state and the normally-closed state of the integrated switch fails in the prior art is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of push button switches, in particular to a push button switch center seat structure. Background Art

[0002] A push button switch is a switch that uses a button to push the transmission mechanism to connect or disconnect the moving contact and the static contact and realize circuit switching. A push button switch is a master electrical appliance with a simple structure and a wide range of applications. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] The push button switch includes a button, a middle seat, and a switch. The middle seat of the existing push button switch is usually a snap-on middle seat and a screw-type middle seat. The button can be adapted to the snap-on middle seat and the screw-type middle seat. The switch of the existing push button switch is usually an integrated switch and a split switch (the integrated switch is that the normally open and normally closed parts are an integrated structure, and the split switch is that the normally open and normally closed parts are a split structure). The integrated switch is connected to the snap-on middle seat by a snap-on method, and the split switch is connected to the screw-type middle seat by screws. This results in that when the existing button switch uses the snap-on middle seat, its switch can only use the snap-on switch, that is, the integrated switch. The existing snap-on middle seat cannot be used in conjunction with the split switch, and the switch is divided into a normally open part and a normally closed part. When one of the normally open or normally closed parts fails when using the integrated switch, the switch needs to be replaced as a whole, resulting in a high cost of use. Utility Model Content
