1. A system to permit a line voltage switching device operable at a first voltage and a first current to provide, when in an electrically continuous state, an output signal to a high-impedance controller input used control the delivery of power at the first voltage from a line voltage source to a load device, the system comprising:
a first node electrically, communicably, coupled to the line voltage switching device to receive a line voltage signal from the line voltage switching device when the line voltage switching device is in the electrically continuous state; a second node that outputs at the first voltage a first portion of the line voltage signal received at the first node, the second node electrically, communicably, coupled through at least one first capacitive device to the first node; a voltage divider electrically, communicably, coupled to the first node, the voltage divider including at least a first resistive device serially electrically coupled to a second resistive device; and a third node that provides a second portion of the line voltage signal received at the first node as the output signal indicative of the electrically continuous state of the line voltage switching device to the high-impedance controller input, the third node electrically, communicably, coupled between the first resistive device and the second resistive device, the output signal at a second voltage lower than the first voltage and the output signal at a second current that is lower than the first current. |
