ELECTROMAGNETIC ACTUATOR WITH OPTIMIZED OPERATION AND ELECTRICAL DEVICE SWITCH HAVING SUCH ACTUATOR.

摘要

Electromagnetic actuator (1) having a movable armature (11) with respect to a fixed yoke (10) and a control coil (3). Means (6) for detecting the separation of the mobile armature (11) comprise a power source (S), a switch switched during a change of position of the mobile armature (11) and means for detecting (60) the state of the switch and sending a control signal (Sig) when the switch is in the open state. The switch is made on the actuator (1), by contact or separation between the mobile armature (11) and fixed (10), the fixed yoke (10) being made in two conductive portions (10A, 10B) respectively connected to the electrical detection circuit (6) and separated from each other by an electrical insulator (14), the contact of the mobile armature (11) with the fixed yoke (10) creating an electrical connection between the two conductive parts (10A, 10B).
