An AC / DC composite switch assembly

Abstract

This utility model discloses an AC / DC composite switch assembly, comprising: a low-voltage sliding switch body, a fixing plate, and a metal plate. The low-voltage sliding switch body is fixedly and electrically connected to a circuit board, which is electrically connected to the main control board of a hair dryer. The low-voltage sliding switch body has a trigger toggle block and multiple positions. A linkage mechanism is fixedly connected to the trigger toggle block. The fixing plate contains a fixed conductive plate with a first high-current contact point at its top. A spring-loaded metal plate is correspondingly disposed with the fixing plate, and a second high-current contact point is disposed at the top of the metal plate to cooperate with the fixing plate and the linkage mechanism. This utility model, through the linkage mechanism, fixing plate, and metal plate, combines the existing power switch and position switch into one, reducing the size of the electrical appliance while also solving the problems of wiring installation process and overall cost, and reducing the safety risks of mixed AC / DC wiring installation.
