A selector switch may be controlled by a single-ended control signal for steering a current through a load or through an auxiliary line. The selector switch may include a first terminal to be coupled to the load, and a second terminal to be connected to the auxiliary line, and two analog switches coupled to respective ones of the first and second terminals and configured to implement a single pole double throw switch so that a conduction or non-conduction state is determined by the single-ended control signal for steering the current through the load or the auxiliary line. The selector switch may also include a circuit defining a positive feedback loop controlling the two analog switches.
