Abstract: A switch assembly and method of operation comprises a housing having top and bottom ends spaced about a longitudinal axis and a selectively movable knob coupled to a plunger arrangement having a shaft that extends from inside the housing to couple to the knob. The switch assembly also comprises a printed circuit board having at least one wiper for engaging a contact extending from the plunger arrangement. A step shaft projects from the shaft of the plunger arrangement such that when a maintained mode of operation is desired by the switch assembly, the step shaft engages a retaining assembly formed by a portion of the housing, and when a momentary mode of operation is desired by the switch assembly the step shaft is positioned such that is free from engaging the retaining assembly.
