Abstract

The invention discloses a light modulation type potentiometer switch for a desk lamp. The light modulation type potentiometer switch comprises a rotary type potentiometer body. A central turning axle extends out from the rotary type potentiometer body. A rotary cap is sleeved on the central turning axle. The inner wall of the rotary cap and the central turning axle are connected in a limiting way through a spline structure. The outer surface of the rotary cap is provided with a noctilucent coating layer. The outer surface of the noctilucent coating layer is provided with an external transparent plastic protective cover. The top of the rotary cap is provided with a groove. The top of the external transparent plastic protective cover is provided with a projecting block. The groove and the projecting block cooperate with each other. By the above-mentioned means, the switch with a simple and reasonable structure has a noctilucent function and makes it convenient for people to turn on the lamp at night. Meanwhile, the noctilucent coating layer does not easily fall.

Description

technical field [0001] The invention relates to the technical field of potentiometers, in particular to a dimming potentiometer switch for desk lamps. Background technique [0002] The potentiometer is a resistive element with three terminals and the resistance value can be adjusted according to a certain change rule. A potentiometer usually consists of a resistor body and a movable brush. Potentiometers are installed on various devices for adjustment. [0003] The rotary potentiometer is a kind of potentiometer that is widely used in potentiometers. It is a common application to use the rotary potentiometer as the dimmer switch of the desk lamp to adjust the brightness of the light. The existing dimmer switch does not have a luminous function, and it is inconvenient when people sleep and wake up at night and want to turn on the bedside table lamp. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a dimmin...
