Abstract

Improvements in timers to threshold devices, comprising a timer circuit of the resistance-capacity type, which delays the application, to a utilization device, of the voltage provided by a power source, characterized in that said devices comprise between said source and the said timer circuit, at least one voltage threshold stage whose priming voltage is fixed to the voltage level of the source, from which the timing can intervene and, if necessary, remain constant.
