Title: Latching relay device
Inventor: FUKUDA TOSHIYA
IPC: H01H47/22
Filed: 1988-12-19
Abstract: PURPOSE:To reduce currents passing through coils to their required minimum amount and also make it possible to accomplish relay action by stopping transmission of electricity to the coils immediately after driving of a relay contact. CONSTITUTION:Set side signals are inputted to the set side terminal 202 of a second relay contact 2 and reset side signals to the reset side terminal 203. When a first control signal is inputted to a driving circuit, the driving circuit then transmits electricity to a set coil 9, whereas when a set side signal is inputted from the common contact 201 of the second relay contact 2 the driving circuit stops transmission of electricity to the set coil 9. Also, when a second control signal is inputted to the driving circuit, the driving circuit then transmits electricity to a reset coil 10, whereas when a reset side signal is inputted from the common terminal 201 of the second relay contact 2 the driving circuit stops transmission of electricity to the reset coil 10. The required minimum amount of currents are thus caused to flow through the coils 9, 10 for driving the relay contacts, and relay action is accomplished as a result.
