Zusammenfassung:The utility model relates to a relay switch which comprises a dual block switch, a dual core relay and a lever switch for controlling the on-off of a circuit. When a point A is closed by the dual block switch, an iron core 41 of the dual core relay attracts the lever switch to lead the circuit to be communicated. When a point B is closed by the dual block switch, an iron core 42 of the dual core relay attracts the lever switch to lead the circuit to be disconnected. Besides comprising a low voltage DC transformer, the utility model also comprises a delay circuit for protecting the service life of the dual core relay. When the utility model is used for controlling a high voltage circuit, the operation is especially safe.
