KJT speed control switch products are mainly developed according to the actual needs of customer sites. The products have a wide range of electricity, and can be applied to 24VDC─110VAC─220VAC (different voltage levels are configured with intermediate relays of different voltages), bringing unified purchasing to users. Easy installation and good interchangeability. The product can effectively and timely handle electrical and process failures such as stalling, jamming, overloading, slow rotation, belt slipping, transmission chain (belt) falling off, transmission shaft breakage, etc. that often occur in motors and mechanical transmission devices. It can play a role in ensuring production and maintaining equipment.
