Claims

[Scope of utility model registration request]

When a voltage is applied to the coil of the relay from a non-constant voltage power source through a parallel line with a resistor and a capacitor, a switching means is connected to the coil of the relay to control driving and non-driving of the relay, as described above. A relay drive circuit characterized in that a voltage from a constant voltage power supply which outputs a lower voltage than a non-constant voltage power supply is applied through a diode to a connection point between the parallel circuit and the coil of the relay.
