Waterproof electric appliance switch

Abstract

A waterproof electric appliance switch comprises a switch base, a springboard, an inner button bracket, an inner button and an outer button. A sealing plate fixed to the switch base is arranged between the inner button bracket and the outer button, the surface jacks of the sealing plate are located on a boss on the surface of the sealing plate, drainage grooves are disposed on the four sides of the surfaces of the switch base and above and under the switch base, water guiding groove are arranged above and below the surfaces of the sealing plate, and the drainage grooves and the water guiding grooves form a smooth drainage channel. Therefore, the waterproof electric appliance switch has good waterproof performance than that of a switch in the prior art. Further, the boss is disposed on theinner button bracket, the inner button bracket has positioning inclined surfaces on both sides of a through hole, the positioning inclined surfaces correspond to the inclined surfaces on the inner button, the lever on the inner button is connected to the spring and is an elastic structure, and the surface of the springboard has two convex structures. Thus, the switch is stable and reliable in switching and positioning.

Description

technical field [0001] The invention relates to a household electrical appliance switch, in particular to a waterproof electrical appliance switch. Background technique [0002] The switches of the prior art mostly comprise a switch back seat, on which a terminal post is provided, the terminal post connects the contacts of the switch, a springboard is provided on the switch contact, and the button controls the springboard to switch off and on. Due to structural reasons, this switch has no waterproof function, and water can easily enter through the gap of the switch button, and the water will directly contact the springboard, which will affect the safety of the switch. The waterproof electrical switch of the prior art just adds an external waterproof cover on the outside of the switch, which is inconvenient to use and not attractive in appearance, and it is easy to forget to close the waterproof cover to cause electrical failure. Contents of the invention [0003] The purp...
