ABSTRACT:
A membrane switch with multiple switch sites in which, at a given switch site, three concavo-convex structures are juxtaposed over a set of switch contacts so that when the key is pressed, the force applied causes the three structures to cooperate to complete an electrical circuit and close the switch. An operator easily can detect when a switch has been effectively closed because of the superior tactile response resulting from the concavo-convex components. Apertured spacers also are provided to allow the contacts to be brought into communication with each other and to provide a distance through which the actuating force must travel to further enhance tactile feedback to the user.
