| 247 | LATCHING RELAY DRIVE CIRCUIT WITH INTERLOCKING WITH THE IGNITION SWITCH OF A VEHICLE | US14368028 | 2012-11-26 | US20150001924A1 | 2015-01-01 | Yukio Kamiya |
| When a trouble is caused to a control signal output function of a controller (9), each of output ports of control signals of the controller (9) is brought into a high impedance state. Turning on or off an ignition switch (IGN) in this state generates an alternative bias signal in a switch signal input circuit (11) or an inverter (13). The generated alternative bias signal is applied to a set coil energizing switch (7a) or a reset coil energizing switch (7b). Thus, a latching relay (5) can be driven on and off, interlocking with an on-operation or an off-operation of the ignition switch (IGN). | ||||||
