HK series switch state indicator is a new kind of multi-functional, analog dynamic indicator device for power switch cabinet. It integrates the primary loop simulation diagram, circuit breaker position, switch state, ground knife position, spring energy storage state, high-voltage live indication, high-voltage live lock and temperature control, etc. The indicator function can be divided and closed. The panel installation method is adopted.

The product provides temperature, humidity, temperature and humidity, condensation control functions. It can also cooperate with the relevant operation control loop and various kinds of anti-misoperation electromagnetic lock to realize the misoperation of the operating handle and protective door of the forced closed switch cabinet. It has the function of preventing live separation, closing the grounding switch (knife brake), avoiding entering the charged interval and improving the safety and anti-misoperation performance of the electrical switch equipment. It has five defense functions. The device can be applied to the live instruction of all kinds of high voltage equipment in the house with the high voltage electrification sensor of corresponding voltage level. The "open lock" indicator light is on in the charged blocking state of the high-voltage equipment, which allows operation.
