Bicolor character display button switch

Abstract

The invention relates to a bicolor character display button switch and mainly solves the problem that an existing button switch cannot directly judge whether a circuit is in the switch-on state or the switch-off state, and misoperation is easily caused. The bicolor character display button switch is characterized in that a bicolor switching sheet (11) is arranged in a press cap (3), characters with two different colors are arranged on the bicolor switching sheet (11), a lamp bead (4) is a three-pin bicolor light-emitting diode, the lamp bead (4) is connected with a switching-on circuit and a switching-off circuit, and two different colors emitted by the lamp bead (4) can respectively stimulate the characters with two different colors on the bicolor switching sheet (11) to glow without causing mutual interference. The bicolor character display button switch adopts the structure of the bicolor switching sheet and the three-pin bicolor light-emitting diode, and the characters with two different colors are arranged on the bicolor switching sheet, so that the exterior of the press cap displays the characters with two different colors in the switch-on or switch-off state to directly indicate the switch-on and switch-off state, the switch is safe and reliable, and no misoperation is caused.

Description

technical field [0001] The invention relates to a button switch, in particular to a two-color character display button switch. Background technique [0002] A push button switch refers to a switch that uses a button to push the transmission mechanism to control the connection or disconnection of the moving contact and the static contact and realize circuit switching. Push button switches are widely used in electrical automatic control circuits. Push button switches are divided into two types: self-resetting structure and self-locking structure. Existing button switches are mainly composed of a type foot, a base shell, a push cap, a lamp bead and a push cap shell. The type foot is equipped with terminals, moving contacts and static contacts. There are extension spring sliding bolts and compression spring sliding bolts that can slide up and down. The extension spring sliding bolts are connected with the moving contact piece and can control the connection or disconnection of t...

Problems solved by technology

[0003] In order to overcome the problem that the existing push button switch cannot directly judge whether the circuit is in the on state or off state, which may easily cause misoperation, the present invention provides a two-color character display push button switch. The two-color character display push button switch adopts a two-color conversion sheet and Two-color light-emitting diode structure, there are two different characters on the two-color conversion sheet, when it is turned on or off, the characters of two different colors are displayed on the outside of the button, directly indicating the on and off status, safe and reliable, and will not cause misoperation
