Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a three-speed switch with a lamp. Background Art

[0002] The switch is used to connect and disconnect the circuit to control the connected electrical equipment. Currently, the rocker switch mainly includes two gears and three gears, and the three-gear rocker switch can control the connection or disconnection of two circuits respectively to achieve the control of two electrical equipment or the switching of two connected circuits.

[0003] The three-speed rocker switch in the related art is usually divided into a three-pin or four-pin rocker switch, wherein the button of the three-pin rocker switch is usually made opaque, that is, without an indicator light. If an indicator light is required, it needs to be made into a four-pin rocker switch.

When the control component is actuated, the indicator light is electrically connected and lights up by hard contact between the filament and the corresponding connection pin. However, in actual use, the use of hard contact of the filament may cause poor conduction, resulting in poor stability and short service life of the product. Utility Model Content
