Pollux 7, correct key inserted and rotated

A push key (or pump key) is one which positions the components by longitudinal motion without rotation. Examples may have a bitting across their leading edge which comes in contact with components as the key is inserted and reaches the proper depth when the shoulder of the key reaches its stop. The most popular lock design that uses push keys are tubular pin-tumblers.
