An improved membrane switch (10) is the subject matter of this patent. The switch (10) includes a pair of transparent, laminar contacts (16, 18) sandwiching a spacer (30) therebetween. The spacer (30) has a window (36) formed therein so that the contacts (16, 18) can be engaged at the location of the window (36) by the application of pressure to one of the contacts (16, 18). Engagement of the contacts (16, 18) closes a circuit to effect a desired function.
