Abstract
A single-coil actuator for low or medium voltage applications which comprises a first assembly which comprises a first casing having a first half-casing and a second half-casing coupled to each other. The first casing defines an internal space housing an electromagnet having a coil and an armature movable between two positions. The first half-casing has a first opening for the mechanical coupling of the armature with an external element, while one of the first or second half-casing has a second opening for the electrical connection of the electromagnet. The electrical connection comprises a first connection element of the socket and plug-type connection which is electrically connected to the coil and positioned in correspondence of the second opening.
