An electrical circuit and method for switching an input voltage onto a load by way of an AC control voltage is provided. A voltage magnitude reduction circuit is configured to be driven by the AC control voltage. A rectifier circuit is operably coupled with the voltage magnitude reduction circuit. Also, a voltage limiter circuit is operably coupled with the rectifier circuit, and an energy storage circuit is operably coupled with the voltage limiter circuit. The voltage magnitude reduction circuit, the rectifier circuit, the energy storage circuit and the voltage limiter circuit cooperatively generate a switch control voltage. An electronic switching unit is then configured to switch the input voltage across the load when the switch control voltage is active. In one embodiment, the input voltage is a DC voltage generated by an AC-to-DC voltage converter circuit configured to convert an AC supply voltage to the DC voltage.
