PLUNGER SWITCH

摘要

An illustrative plunger switch may include a movable contact assembly movable with respect to a fixed pair of conductors. The movable contact assembly may include a plunger having a rod fixed to a cage, and a shorting bar moveable with respect to the cage of the plunger but at least partially constrained by the cage of the plunger. The shorting bar may have contact ends that are in line with the internal contact ends of the fixed pair of conductors. The shorting bar may conductively connect the pair of conductors via the contact ends of the shorting bar in only one of an unactuated position or an actuated position of the plunger. A retention spring may be situated in the cage of the plunger for biasing the shorting bar toward the fixed pair of conductors.
