ABSTRACT:
An actuator with a top plate comprises at least one duct opening for a respective electric contact pin. A contact stud carrier with a contact stud is placed over the contact pin. To prevent the possible ingress of plastic into the duct opening between a gap (s) between the contact stud carrier and the top plate during extrusion coating of the actuator or its top plate, according to the invention it is proposed that a sealing washer be located onto the open side of the duct opening of the top plate to provide a hermetic seal. As a result, the contact stud carrier can advantageously always be arranged independently of the thickness of the sealing washer such that a specified actuator length (L) can be precisely maintained. This simplifies the production process for the actuator and reduces its production costs.
