Abstract
An electromechanical switching circuit comprises an integrated circuit (IC) having an input terminal, an output terminal and a control terminal. The IC is arranged based on a voltage transition at the control terminal, sampling the voltage level at the input terminal and supplying it at the output terminal. The output voltage level is maintained at the output terminal until a voltage transition at the control terminal. A control circuit connected to the control terminal includes a first monostable switch whose actuation causes a voltage transition at the control terminal so the voltage level applied at the input terminal is supplied at the output terminal. An output circuit includes a second, electromechanical, monostable switch whose contacts are moved to their unstable state in response to a first voltage level at the output terminal and allowed to resume their stable state in response to a second voltage level at the output terminal.
