ILLUMINATED MEMBRANE SWITCH

摘要

An electroluminescent switch is described incorporating an electroluminescent lamp assembly (25) and one or more membrane switch assembly (24). The base electrode (21, 14) of the electroluminescent lamp additionally functions as the means by which the membrane switch may be closed upon actuation by a user. The membrane switch (24) can be constructed from two electrodes arranged so that the conductive layer when brought into contact with said electrodes shorts the electrodes thereby closing the circuit. Applications for the membrane switch (24) include electronic devices where panel switches are required or electronic devices requiring particularly thin switches which are to be backlit.
