Abstract
An elastic member adapted to apply a contact pressure to a movable terminal of a relay includes a fixed part and a pair of elastic arms. The fixed part is adapted to be fixed to a movable seat of the relay. The pair of elastic arms are connected to respective sides of the fixed part and extend obliquely therefrom. End parts of the pair of elastic arms are adapted to abut against two ends of the movable terminal of the relay and apply a predetermined contact pressure thereon.
