Abstract

A button device comprises a casing, a button and a switch component. The casing is provided with a button hole, and a clamping portion which surrounds the button hole in a circle and axially extends along the button hole is arranged on the inner side of the casing. The button is held in the button hole, one end of the button is provided with a stopping portion, and the stopping portion surrounds the outside of the button in a circle, stops the button from separating from the button hole and is provided with a matching portion. The matching portion surrounds in a circle and is clamped with the clamping portion. The switch component is held in the casing to press the button, so that the button deforms elastically and is abutted against the switch component to trigger a switch module. By arranging the clamping portion extending along the button hole axially on the casing and arranging the matching portion clamped with the clamping portion on the button, the button device is effectively waterproof and dustproof.

Description

【Technical field】 [0001] The invention relates to a button device, in particular to a waterproof button device in a lamp. 【Background technique】 [0002] The button device is an essential part of the lamp. The light source can be turned on and off through the button device, and some button devices also have the function of adjusting the light intensity. The button device can be designed into different shapes according to the overall structure of the lamp to achieve an aesthetic effect. [0003] During the long-term use of general lamps, dust and water may enter the interior of the button device, causing circuit failure or destruction. This situation is even more serious when lamps are used in harsh environments. 【Content of invention】 [0004] Based on this, it is necessary to provide a dustproof and waterproof button device. [0005] A button device includes a casing, a button, and a switch assembly. The housing is provided with a button hole, and the inside of the hou...
