Single push-button switch having visual position indication

摘要

A switch comprising a housing and a switch activating rod extending within the housing. An electrically conductive element is displaceable by the rod within the housing. The rod is resiliently biased axially in one direction to a first position where the conductive element will engage a first set of electrical contacts in the housing. Lock means is provided and associated with the rod for locking the rod in a further position when displaced axially in opposition to the said first position. The conductive element engages a second set of electrical contacts when the rod is locked in the said further position. The rod is unlocked and urged to the first position by depressing the lock means.
