Patent ID: 7015777

Claim:
A switch device for opening and closing at least one electrical line, the device comprising: at least one stationary portion, at least one pair of contact terminals; at least one drive member comprising a contact piece suitable for being displaced axially between a closed position in which the contact piece contacts simultaneously the two contact terminals of said at least one pair, interconnecting them electrically, and an open position in which the contact piece is spaced apart from said two contact terminals; at least one actuator comprising an actuator element that is movable and suitable for driving said at least one drive member; a generally flexible holding element connecting at least one of the actuator element and the drive member to said stationary portion of the device, said holding element having at least one first region secured to said stationary portion, and at least one second region secured to the at least one of the actuator element and the drive member, said second region being suitable for flexing relative to at least one adjacent region of the holding element so as to enable the at least one of the actuator element and the drive member to be displaced substantially in rectilinear translation; wherein said at least one second region is a non-central region of the holding element.
