Abstract
Key switch assembly comprises a frame having a column in which a plunger is contained. The plunger is biased to an extended position by a spring and is movable to its depressed position. A bell crank is mounted adjacent to the column and has a camming arm which extends alongside the plunger and a switch closing arm. The plunger has a stiffly flexible camming rod and the column has a cam which flexes the camming rod during depression of the plunger so that it engages the camming arm and causes the switch closing arm to close the switch associated with the plunger and frame. The switch is closed for only a brief interval during depression of the plunger and the switch closing lever returns to its normal position after the camming rod moves past the cam.
