Abstract
A tactile feedback switch having a contactor element having a curvilinear portion which temporarily changes from a substantially convex shape to a substantially concave shape upon movement of the contactor element into engagement with an electrical contact. An indentation in the contactor element reduces the force otherwise needed to be applied to the top portion of the contactor element in order to maintain the contactor element in engagement with the electrical contact.
