Claims

[Scope of utility model registration request]

It has a normally open first relay contact interposed between the battery and a predetermined load, and a coil that is energized when the circuit to the battery is closed by the ON operation of a switch, and closes the first relay contact. a first relay, a normally closed second relay contact connected in series between the coil of the first relay and the battery, and a first relay contact or a second relay contact when the switch is in the ON state; a second coil having a coil that is energized and opens a second relay contact when the relay is in a closed state;
and a self-holding circuit that maintains the first relay contact in a closed state when the first relay contact is closed, regardless of whether the second relay contact is opened or closed, and the first relay contact is in a state in which the first relay contact cannot be closed. A relay unit characterized in that when the switch is turned on, the second relay contact causes chattering, and the coil of the first relay is intermittently energized.
