OPERATION CIRCUIT OF SWITCH

摘要

PROBLEM TO BE SOLVED: To provide an operation circuit which performs release delay and high-speed interception by a simple configuration.SOLUTION: Between terminals 10a, 10b of a slave station 10, quick contact switches 11a, 11b and a diode 12 are provided. Between terminals 20a, 20b of a switch 20, a holding coil 21 and a closing coil 22 are connected in series. A relay switch 23 and a break contact 24 are connected to both ends of the holding coil 21. Furthermore, in the switch 20, a delay circuit 30 constituted of diodes 31, 32, a relay 34, a capacitor 35 and resistors 33, 36 are provided. At the time of delay opening, the relay switch 23 interlocking with the relay 34 is actuated by the capacitor 35.
