Title
(EN) ELASTOMERIC SWITCH FOR ELECTRONIC DEVICES
(FR) COMMUTATEUR ELASTOMERE POUR DISPOSITIFS ELECTRONIQUES
Abstract
(EN)
There is provided an elastomeric switching device (10) for use with electrical circuits, such as those located on or connected to a printed circuit board (20). The elastomeric switching device comprises an elastomeric pad (40) constructed from a plurality of parallel strips of conductive material (42) sandwiched between layers of non-conductive or insulating material (44) together with a moveable conductive connector (50) which is aligned with the elastomeric pad. The elastomeric pad is predisposed in contact with the circuits or circuit traces (20, 22, 24) located on the printed circuit board. The moveable connector includes a moveable conductive contact (56) and a flexural diaphragm (52). The moveable conductive contact establishes electrical connections between the affected circuits via the conductive strips of the elastomeric pad. A housing maintains the proper alignment and orientation of the elastomeric pad and the moveable conductive contact relative to the circuits or circuit traces.
(FR)
On décrit un dispositif de commutation élastomère (10) destiné à des circuits électriques tels que ceux placés sur une plaquette de circuit imprimé (20) ou connectés à une telle plaquette (20). Ce dispositif de commutation élastomère comprend une plage élastomère (40), construite à partir de plusieurs bandes parallèles d'un matériau conducteur (42) intercalés entre des couches d'un matériau non conducteur ou isolant (44), et un connecteur conducteur mobile (50) aligné avec cette plage élastomère. Cette dernière est pré-positionnée en contact avec des circuits ou rubans de circuits (20, 22, 24) disposés sur la plaquette de circuit imprimé. Le connecteur mobile comprend un contact conducteur mobile (56) et un diaphragme souple (52). Ce contact conducteur mobile établit des connexions électriques entre des circuits souhaités par l'intermédiaire des bandes conductrices de la plage élastomère. Un boîtier maintient l'alignement et l'orientation appropriés de la plage élastomère et du contact conducteur mobile par rapport aux circuits ou rubans de circuits.
