ABSTRACT:
The setting system of this invention includes a contactor provided with a blade adapted to come into repeated contact with a contact stud thereby to act on an electrical circuit. The contactor is operated by a stem bearing a crown and has a lock which prevents the blade from coming into accidental contact with the stud (for instance following a shock) when said stem is in its pushed-in rest position.
