ABSTRACT:
A keyboard spacer for inhibiting the depression of selected push buttons upon a keyboard is shown including a longitudinal trunk having a first resilient arm which engages a key stem of a keyboard switch between the switch and the push button. As the first resilient arm yields, a second latching arm snaps over the key stem for retaining the spacer in the position desired. The spacer, which inhibits the depression of the push button, may be easily removed if push button operation is desired.
