In the conventional art, the remote control switch is a device that uses monitoring to operate the opening and closing of the switch. It is generally used as a load distributor, or remotely controls the closing and opening of the switch. Generally speaking, it can only The use of switches is limited to fixed brand specifications and does not have common mutual capacitance, resulting in insufficient interchangeability and inability to achieve economy. Due to the above deficiencies, all conventional remote control switch products cannot solve the above common problems.

In the conventional art, the working power supply of the control power supply of the remote control switch comes from two points on the primary side of the switch. When the power circuit is out of phase, the working power supply comes from the phase sequence of the out of phase, which will cause The remote control switch cannot be actuated. Due to the above deficiencies, all remote control switch products in the prior art cannot solve the above common problems.

In the conventional art, the remote control switch performs the opening, closing and closing of the switch by The external operating switch or the actuating contact of a sensing device is controlled.

When the remote control switch is equipped with a shunt trip or If the voltage is insufficient, the coil will trip. If the external power supply is unstable, it will flash. The voltage drop among the switches will cause the switch of the remote control switch to trip, resulting in a power outage. Without the above, all remote control switch products in the prior art cannot solve the above common problems.

In the conventional art, the remote control switch is controlled by an external operating switch or an actuating contact of a sensing device when the switch is turned on and off. When the remote control switch is overloaded or short-circuited in the power circuit, In an abnormal state, the switch will trip on its own (the original electrical characteristics of the switch). Since the remote control switch is operated by external monitoring, it may be re-energized and closed before the fault is eliminated, causing a secondary accident. If the above is missing, All remote control switch products in the art cannot solve the above common problems.
