Abstract

A system and method for protecting a coil structure in a controlled switch. In one embodiment, the invention relates to a circuit including at least one load switch connectable between a power source and a load and at least one auxiliary switch, each switch actuable between a default position and a switched position, a coil structure configured to actuate the at least one load switch and at least one auxiliary switch in response to a control input, the coil structure switchable between an actuating configuration for actuating the at least one load switch and the at least one auxiliary switch from the default position, and a holding configuration for holding the at least one load switch and the at least one auxiliary switch in the switched position, and a resettable current limiting device configured to limit the current flow in the actuating configuration of the coil structure if the current flow exceeds a threshold for a predetermined period of time, wherein the at least one auxiliary switch is configured to switch the coil structure from the actuating configuration to the holding configuration.
