Abstract
A push-button mechanism for plunger-type electrical switches of the type having a push rod actuator, is provided with a base unit having a pair of undercut tabs. A button member has a pair of heels respectively receivable in the undercut of the tabs for sliding movement of the button to move the push rod actuator to thereby change state of the switch. The button member is retained to the base unit by snap-fit between the heels and the tab undercuts. The switch has a pair of flanges; and the base unit has a pair of tapered slots respectively aligned with the flanges and adapted to releasably receive the flanges upon assembly of the switch to the base unit. The push rod actuator has a recess; and the button member has a pair of opposed ribs aligned with the recess and adapted to be received by the recess upon assembly of the switch to the base unit.
