Abstract
A rotary, push-pull switch (20) for use in an automobile has a rotating ceramic coated metal substrate rheostat (48) and a supplemental switch (52) which opens and closes a dome light bypass circuit. The supplemental switch (52) is mounted internally to the rotary, push-pull switch (20) adjacent to the rotating rheostat (48) disposed on a shaft (36). A projection (88), which is radially disposed on the shaft (36), is used to actuate the supplemental switch (52) by engaging a resilient contact leaf (60) when the shaft (36) is rotated sufficiently. The engagement of the projection (88) and contact arm (60) causes the separation of a contact (62) and terminal (64), opens the dome light bypass circuit, and precludes energizing the dome light.
