Double solenoid valve control voltage energy

The utility model relates to a double-voltage and energy-saving controller with solenoid valve, which can realize double-voltage control of the solenoid valve. The technical proposal is that the information output terminal of the single-chip microcomputer is connected with the console of the switch circuit, the information input terminal of the switch circuit is connected with electrical source (VH), and the information output terminal of the switch circuit is connected with an ending of the solenoid valve coin and also is connected with the electrical source (VH) through a diode. The utility model has the advantages that the controller can save electric energy and extend the service life of the solenoid valve.
