Title:
RELAY CIRCUIT
Document Type and Number:
Japanese Patent JP2770614
Kind Code:
B2
Abstract:
PURPOSE: To provide a relay circuit capable of providing two-stage control output with one switch.
CONSTITUTION: When a latching type relay 9 is laid in reset state, a make contact 10 is connected to a first relay 2. Therefore, when a switch 11 is pushed, the first make contact 3 and third make contact 5 of the first relay 2 are closed, and an output is transmitted from a first output terminal 17 to charge a capacitor 15. When the switch 11 is released, the latching type relay 9 is set by the discharge cttrrent I of the capacitor 15, and the make contact 10 is connected to a second relay 6. When the switch 11 is pushed again, the make contact 8 of the second relay 6 is closed, and an output is transmitted from a second output terminal 18, and the break contact 7 of the second relay 6 is opened to interrupt the output from the first output terminal 17. When the switch 11 is released, the discharge current I from the capacitor 15 is run into a reset coil to return the relay into reset state.
