Title:

SOLENOID VALVE WITH SWITCH

Document Type and Number:

Japanese Patent JP3709241

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To eliminate the generation of wrong operation by providing a cover for solenoid, a printed board for connecting a solenoid terminal and a receiver terminal to each other, and providing a switch for connecting and disconnecting the electrical connection of both the terminals in a cover freely to be moved.
SOLUTION: When a printed board 24 is installed in a power supply unit 13, solenoid terminals 25a, 25b are electrically connected to receiver terminals 18a, 18b. A switch 34, in which a conductive plate 38 is assembled, is assembled in a cover 23, and fitted to the power supply unit 13. With this structure, at the time of moving the switch 34 downward, the conductive plate 38 is electrically connected to the pins 28a, 28b. When the switch 34 is moved upward, electrical connection of the pins 28a, 28b are disconnected, and the operation of a solenoid valve by solenoids 12a, 12b can not be performed, and the solenoid valve can be operated by pushing and releasing manual operating means 15a, 15b. With this structure, a relation between the switch and the solenoid valve to be manually operated becomes clear, and even in the case where plural solenoid valves are provided, wrong operation of switch is prevented.
