ABSTRACT:
A multipole, double throw relay includes a base with a coil and armature mounted at the center of the base. A terminal block with an L-shaped cantilever contact blade is mounted on one side of the coil. The contact blade extends up and over the coil, passes through a contact blade lifter affixed onto the armature and projects between a pair of contacts associated with a contact block assembly mounted on the opposite side of the coil. Operation of the coil causes the lifter to engage and move the flexible contact blade. The lifter has a lost motion action that prevents contact flutter and provides for a more efficient switching operation.
