Electrical unit with turn-off switch and system

Abstract

An electrical unit may include a current controller including an electrical regulator, a control circuit connected to a first input of the electrical regulator, a timer connected to a second input of the electrical regulator, and/or a turn-off circuit including a turn-off switch. The current controller may be configured to provide a first output signal in a first mode and a second output signal in a second mode. The current controller may be configured to transition from the first mode to the second mode based on a timer output of the timer. An electrical system may include an electrical unit and or a switch connected to the electrical unit. The switch may include a coil. The electrical unit may be configured to provide the first output signal to the coil in the first mode and provide the second output signal to the coil in the second mode.
