daw series dustproof (multi-function) dc variable speed trigger switches

产品描述product description

daw series are one general type dc variable speed trigger switches, integrated dustproof and mechanical brake contact,without reversing box, commonly for used in dc portable power-tools and gardening tools such as: cordless rotary hammers,cordless reciprocating saws, cordless jig saws, cordless angle grinders, cordless grass trimmers, cordless blowers, etc.


◆the switches combine compact size with high performance, a wide scope of heat sink for mosfet and further options provide .easy to mount solutions. they employ spst-no with by-pass contact, integrated pwm (pulse width modulated) electronics in various dimensions.
◆average duty cycle of motor voltage 8 - 50% to 8 - 90% (according to client's demand), then by-pass to battery voltage.
◆optional with the function or accessory as follows:
→external mosfet version→trigger covered with rubber
→auxiliary led and wires-→ auxiliary wire for temperature test
→multi-function, optional soft start, under-voltage protection, over current protection, battery temperature pretection
