Abstract

A switch configured to contact an exposed contact on an edge of a multilayer circuit board when selectively activated. The switch is particularly useful for electronic equipment such as mobile phones, PDA's, etc. where space for key contacts on the circuit board is limited. By facilitating connection to terminals formed on edges of a circuit board and/or edges of layers of multilayer circuit boards, the switch provides additional options for button locations on the electronic device heretofore requiring routing of wiring.
