Abstract
A plunger operated lock in which the lock operating plunger is mounted in a plunger housing inside the lock housing and is axially movable therein. The plunger housing is spring biased to the locking position, and the plunger is spring biased to a medial position in relation to the plunger housing. To allow the plunger to move to the un-locking position, the plunger housing must be moved toward the unlocking position far enough to substantially fully compress its biasing spring, and the plunger must be moved axially in the plunger housing toward the unlocking position.
