Abstract

This invention relates to a combination multi-contact synchronous slide switch and in particular to one which may be accurately operated and easily assembled. The switch mainly includes a PC board, a sliding plate, a turning axis and two clipping rods. The sliding plate is pressed firmly against the PC board by the clipping rods. The sliding plate slides by way of a cog and a turning axle. The sliding plate can slide on the PC board assembly by way of a spring, a steel ball and several slipping holes on the PC board. A number of contact plates are clipped in concave channels formed at the back of the sliding plate. When the sliding plates slide, they are able to contact the corresponding points on the PC board to operate the switch. Further, the sliding plate is formed with convex and concave edges thereby enabling it to be easily interconnected with other sliding plates.
