Electromagnetic relay

The present invention relates to a switch device for opening and closing at least one electrical line, the device comprising:

Switch device for opening and closing at least one electrical line

A compact snap-action switch for high frequency switching applications comprising a housing of electrically conductive material having a horizontal outer wall with an opening formed therein; two spaced contact terminals disposed within the housing and having contact surfaces in a common plane proximate to and parallel with the plane of the outer housing wall; a rectangular metal contact element adapted to bridge the gap between the contact surfaces of the contact terminals in a closed position and to be snapped into an open position spaced from the contact surfaces; an actuator element having a lower end portion supporting the rectangular metal contact element and having an upper end portion disposed above the housing; a cradle support for the operating member; two parallel flexible strips being freely supported therein and being secured to the operating member; the cradle support being mounted above the outer housing wall and accommodating limited vertical displacement of the operating member between a switch closing position in which the metal contact element contacts the spaced contact terminal surfaces and a switch opening position in which the metal contact element is spaced above the contact terminals; the parallel flexible strips normally biasing the operating member in a direction away from the contact surfaces; the parallel flexible strips being parallel to one another and forming with the operating member three sides of a parallelogram in a manner whereby the flexion of the flexible strips provides strictly axial translation of the operating member between the switch opening and the switch closing positions.
