Abstract
An assembly includes an electromagnetic actuator () and a voltage response arrangement () to enable the position of the armature () within the actuator to be monitored. The actuator includes two coils () joined together in series, the armature being switchable between at least two magnetically latched stable rest positions by passing a current pulse through the coils, and an output contact () electrically coupled to the junction () between the coils to facilitate monitoring of the voltage at the junction. The voltage response arrangement () is electrically coupled to the output contact () so as to provide an output signal giving an indication of the position of the armature () in response to the voltage generated on the output contact when a current pulse is passed through the coils (). A method of monitoring the armature position is also provided.
