The relay contacts SWl automatically close when a closing current is passed through the relay and is thereafter maintained closed so long as a holding current, less than the closing current, passes through the relay.

The invention describes a method for limiting a switch-on current in an electrical system which is supplied with power by a battery (100).

The relay contacts SWl automatically close when a closing current is passed through the relay and is thereafter maintained closed so long as a holding current, less than the closing current, passes through the relay.

A third current is initiated on the close coil.

This invention is useful in opening and closing alternating current electric circuits.

A first current is provided on a close coil of the injector.

A circuit testing closer is capable of closing a power distribution circuit and interrupting the resulting current at the next current zero.

The countercurrent conduits (10) are provided with a closure member (4) susceptible of being controlled according to their opening or closing status.

As long as the inductor current is above the valley current threshold turn on of the low side switch is inhibited.
