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

产品描述product description


dak series are one general type dc variable speed trigger switches,integrated dustproofmechanical brake contact and reversing box, commonly for used in dc cordless portable power-tools such as: cordless drills, cordless screw drivers, cordless rotary hammers, cordless impact wrenches, 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 valrious dimensions.
◆average duty cycle of motor voltage 8 - 50% to 8 - 99%, then by-pass to battery voltage (according to customer's demand).
◆optional with the function or accessories 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 protection
