One kind by the microcontroller and power electronics devices composed of new switching devices

Non-contact switch, a micro-controller and the composition of the new power electronics switching devices, by mcb circuit breaker impedance value of the load current step change, thus completing the circuit off. The main features of non-contact switch is no movable contact member, turn-on and turn-off does not occur when the arc or electric meter action, long life, high reliability, suitable for fire, explosion, moisture and other special environments.
