Document Type and Number:
WIPO Patent Application WO/2019/153562
Kind Code:
A1
Abstract:
The present invention relates to a brushless integrated switch, comprising a base, a cover plate, a button, a push rod, a PCB, a direction switching unit, a speed adjustment elastic slide piece, and a main control elastic slide piece. The direction switching unit comprises a direction switching slider and a direction switching lever. A direction switching elastic slide piece is disposed at a bottom portion of the direction switching slider, and a slide slot is disposed in a side wall of the direction switching slider. Direction switching signal copper foil, speed adjustment signal copper foil, and main control signal copper foil are disposed on the PCB. The direction switching signal copper foil, the speed adjustment signal copper foil, and the main control signal copper foil respectively correspond to the direction switching elastic slide piece, the speed adjustment elastic slide piece, and the main control elastic slide piece. In the present invention, a main control circuit, a speed adjustment circuit, and a direction switching circuit are integrated on one PCB and are integrated with a mechanical signal portion of the switch, thereby reducing required assembly space, shortening a control loop, eliminating the need for circuit wiring, and reducing circuit interference. The present invention has a simple structure, and eliminates the need for a circuit board, control wiring, and wiring terminals, thereby reducing product costs.
