◆dak系列是一款通用型的直流扳机调速开关，集成防尘和机械刹车接点，内部带换向结构，应用于各类直流充电式手持电动工具，如：充电式电钻、充电式电锤、充电式螺丝起子、充电式冲击扳手等。
◆dak series are one general type dc variable speed trigger switches，integrated dustproof, mechanical 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.
◆本开关结构紧凑效率高，大面积的固定式散热片为开关的安装提供方便。开关内部为单极常开带直通接点结构，通过改变输入脉冲的占空比来控制场效应管的输出电压，而实现电子调速功能。
◆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。
◆可选带以下功能或附件:
→外置mos管→智能调速功能，可带软启动、欠压保护、过流保护、电池过温保护
◆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.→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
◆输入端/输出端 input side/output side:
→焊接端子 solder terminal
