dqk series dustproof dc trigger switches

产品描述product description

dqk series are special type dc trigger switches, integrated dustproof, designed specially for used in brushless dc power-tools such as: brushless cordless drills, brushless cordless screw drivers,brushless cordless impact wrenches, etc. with special design for assembly with pcb, needn't any wires.


◆the switches combine compact size, optional with the function or accessories as follows:
→on-off version with linear potentiometer
→on-off version with reversing and linear potentiometer
→diode externally
→trigger covered with rubber (overmolding)
