Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a light touch switch with a dustproof structure. Background Art

[0002] A touch switch, also known as a push button switch, includes a base, a conductive plate, a metal spring, a pressing piece and a cover plate. When in use, pressure is applied in the direction of the switch operation to meet the operating force conditions, and the switch function is closed and connected. When the pressure is removed, the switch is disconnected.

[0003] For example, a Chinese utility model patent with authorization announcement number CN214378140U discloses a touch switch with a dustproof structure, including a switch body and a button and a pin installed on the switch body, wherein an annular frame is fixed on the top of the switch body, a dustproof sleeve is provided on the outer sleeve of the button, and the dustproof sleeve is formed with an annular edge outwardly, a sealing cover is screwed on the annular frame by a thread, and a pressure ring in contact with the annular edge is formed outwardly on the bottom of the sealing cover. In the utility model, the dustproof sleeve is arranged on the outside of the button, and after the sealing cover is connected to the annular frame, the pressure ring presses the annular edge to prevent dust from entering, thereby playing a sealing role. After the limit hook is engaged with the limit frame, the annular frame can drive the positioning block to engage between two adjacent protrusions, thereby realizing the limitation of the sealing cover and preventing the sealing cover from being separated from the annular frame due to vibration, so that the pressure ring always remains in a state of pressing the annular edge, and the reliability is higher.
