Please Note: The soft start module is only available for brushed motors. Please allow a little size errors due to manual measurement. This product adopts imported chips, and the package is designed and packaged according to the built-in installation requirements. Almost all the handles and shells of electric tools can be installed in it. 3 kinds of compound start modes: current limit start mode; voltage ramp start mode; smooth and stable start mode. Fine workmanship and good performance.Easy to use.Long service life. Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same. The starting current is reduced by installing the starting module and the machine starts up smoothly. This usually prevents the fuse from blowing when it is switched on. Due to the small design, the module can be easily accommodated in almost any machine or power tool within the housing. Made of high quality materials, durable Soft start switch for electric tools, high-quality materials, industrial grade, precision machining, exquisite craftsmanship, accurate measurement, convenient and fast, professionally manufactured, not easy to break, durable and wear-resistant, high stability, high concentricity. Retrofit module 230V to 20A current load for soft starting machines and power tools Version with 2 connecting wires -Dust-proof package on the back After installing the soft start module, the machine will no longer start so abruptly, but will reach full speed in a short time (about 1-5 seconds) after turning on the machine.The motor is thus significantly less stressed when switched on. This protects the bearings/gears and extends the life of the moving parts. Size: approx. 36 * 22mm/1.41 * 0.86in Material: Plastic + Metal Current: 20A Material: plastic metal Motor type: brushed motor Forward and reverse direction: no Power Type: AC Power Please Note: The soft start module is only available for brushed motors.
