Abstract
Electromagnetic relay comprising resilient U-shaped tongues having each a pair of arms resiliently engaging fixed contact studs for electrically interconnecting them, and a movable control member adapted to move one of the arms of each tongue away from the corresponding contact stud, for breaking the electric connection. This relay further comprises a second control member movable in a direction opposite to that of the first control member and adapted to co-operate with the first control member for clamping the U-shaped tongue and move the two arms thereof away from the relevant contact studs.
