Abstract (en)
[origin: EP0877406A2] The switch has an electromagnetic system with a coil (10) which is connected in series with at least one circuit component (13,14) across which a constant voltage drop is obtained. The circuit component may be provided by a Zener diode or a pair of opposing Zener diodes connected in series, allowing the polarity of the voltage applied across the series circuit terminals (11,12) to be reversed.
