Detailed Description

Referring to fig. 1-6, the control switch of the present invention comprises a housing 1, a PCB 2, a button 3 and a silica gel button 4, wherein the PCB 2 is mounted in the housing 1, and the button 3 is mounted on the top of the housing 1. In order to ensure that the button 3 can slide up and down in the shell 1, a group of guide grooves 11 are formed in the periphery of the bottom of the button 3, and a group of guide edges 12 matched with the guide grooves 11 in a guide mode are formed in the inner wall of the shell 1, so that the button 3 slides up and down along the guide edges 12. After the button 3 is arranged, the outer ring 21 is clamped into the top of the shell 1 for fixing. Silica gel button 4 parcel is on PCB board 2, electrically conductive button on the silica gel button 4 cooperates with the control scheme on the PCB board 2 to the realization is to the control of equipment. The known technology of the silicone key 4 is not described herein. Be equipped with the first leaded light post 5 of three stereoplasm and the post 6 that presses of an at least stereoplasm on silica gel button 4, PCB board 2 corresponds first leaded light post 5 department is equipped with the LED pilot lamp. The pressing column 6 is used for pressing the conductive button on the silica gel key 4. The button 3 lower extreme be equipped with a set of vertical interval set up leaded light post installation cavity 7 with apply pressure in the portion of exerting pressure 8 at 6 tops of pressing the post, install second leaded light post 9 in the leaded light post installation cavity 7, first leaded light post 5 top stretches into in the leaded light post installation cavity 7, just first leaded light post 5 with it supplies to reserve certain stroke space between the second leaded light post 9 the button 3 activity.
