Module switch and supply - application to the start of a fluorescent tube

摘要

The present invention relates to a switch and supply module comprising a static switch intended to be connected between two terminals (a1, a2) of a load circuit, the voltage changes periodically by 0, and means for supplying, from the voltage at the terminals (a1, a2), a voltage supply. This module comprises means (th2, z) in order to inhibit the closure of the static switch (th1) as long as the supply voltage has not reached a predetermined value.
