Abstract

Improvements in the electrical switches, characterized in that the switch includes a hollow body, a drive rod mounted to perform axial movement in the body, a first elastic member that pushes the stem into a rest position, a first bridging contact that can sliding on said stem, a contact carrier on said stem and movable with the stem, a second bridging contact supported by said contact carrier and axially movable with respect to it in one direction, a second elastic member acting between the first and second bridging contacts to pushing the first and second bridging contacts axially away from each other, said second elastic member being weaker than said first elastic member, a first set of fixed electrical contacts carried by the body and with which the first bridging contact cooperates in the switch rest position, a second set of contacts the Fixed body-worn metrics with which the second bridging contact cooperates in the commutator rest position, a third set of fixed electrical contacts with which the second bridging contact cooperates during movement of the actuating rod against action of said first elastic member, and a stop member carried by said stem and with which said first bridging contact can cooperate during the movement of said stem against the action of said first elastic member, said second bridging member being spaced from said third set of fixed contacts, in the rest position of said stem, for a distance greater than the distance by which the stop member is spaced from said first bridging member, so that during said movement of the stem the second set of fixed contacts is opened before the opening of the first set of fixed contacts, and said first set of fixed contacts is ab rt before the closure of the third set of contacts.
