A rollover switch has a housing carrying a depressible cover coupled to a switch whereby a depression of the cover in response to contact being made between the cover and an object movable across a first surface of a playfield of an amusement game functions to activate the switch. A mounting collar is sized to be positioned within an opening formed in the playfield wherein the opening extends between a second surface of the playfield and the first surface of the playfield. The mounting collar and the housing of the switch assembly have cooperating features that allow the switch assembly to be adjustably mounted within the mounting collar to thereby allow the cover to be positioned at a desired location relative to the first surface of the playfield.
