Description

Technical Field

[0001] The utility model relates to the field of lamps with waterproof switch structures, and in particular to a waterproof and breathable switch and a lamp. Background Art

[0002] The toggle switch switches the circuit by turning the switch handle to switch the circuit. Common types of toggle switches include single-pole double-position, single-pole triple-position, double-pole double-position and double-pole triple-position. They are generally used in low-voltage circuits and have the characteristics of flexible slider movement and stable and reliable performance. Toggle switches are widely used in lamps with adjustable color temperature. There is a waterproof toggle switch configured on the lamp, but since heat is generated when the lamp emits light, the gas in the internal sealed cavity will expand, so a vent is needed for pressure relief. However, the provision of a vent will cause water ingress, and the waterproof function will no longer exist. Therefore, it is very important to obtain a waterproof and breathable switch and lamp that overcome the above defects. Utility Model Content
