Title: Relay control device
Inventor: TOYOIZUMI KIYOTO
IPC: H01H47/00
Filed: 1995-04-19
Abstract: PURPOSE: To prevent wearing of contacts of a relay by restraining generation of an arc at the contact. CONSTITUTION: When a switch 2 is turned off, voltage generated by a low voltage power supply 7 decreases gradually. The voltage serves as the voltage to drive a relay 3 and divided with resistors 4, 5, and then monitored by a control part 6. When the value is below a specified level the control part 6 controls a transistor 9 to open the relay 3. Accordingly the relay drive voltage reaches open voltage sharply through normal switching operation without falling in a slope form, and the time for generating an arc is made short, resulting in prevention of wear in a contact of the relay.
