Abstract
The utility model discloses a dual power supply switch, which comprises a switch. The switch comprises two incoming lines respectively connected with a common power supply and a standby power supply and an outgoing line connected with a load. A relay connected with a terminal block of the switch is arranged inside the switch. A coil of the intermediate relay is arranged between a terminal block A1 and a terminal block A2 of the common power supply. An opening point of the intermediate relay is connected with the terminal block A1 of the common power supply. A closing point of the intermediate relay is connected with the terminal block B1 of the standby power supply. In the utility model, the intermediate relay is arranged inside the switch, and thus, the complexity of connection between the terminal blocks and the power supplies of the dual power supply switch is reduced and external connection is simpler so as to reduce failure rate caused by errors which are generated by fussy connection.
