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

产品描述product description


dew 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.


◆开关输出端的平均电压为总电压的8- 50%至8- 90%,也可以按客户要求进行定制,开关按到底由直通接点接至电池端电压.
◆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 ofmotorvoltage8-50%to8-90% (according to client's demand), then by-pass to battery voltage.
◆optional with the function or accessory as follows:

→external mosfet version
