A switching device comprises a first and second connector, a first and second input, an output, a switch connected between the first connector and the second connector, a current sensor configured to measure a current flowing through the switch, and a controller connected to the current sensor, the switch, the first input, the second input, and the output. The controller is configured to: operate the switch based on a first control signal at the first input; connect the second control signal at the second input to the output; operate the switch to open in response to the current flowing through the switch exceeding a predetermined current limit; and disconnect the second control signal from the output in response to the current flowing through the switch exceeding the predetermined current limit.
