LIQUID CRYSTAL DISPLAYS FOR TELEPHONE SETS AND OTHER TELECOMMUNICATIONS TERMINALS Abstract of the Disclosure Liquid crystal display (LCD) devices are becoming more widespread in use because of low power requirements, but such devices are expensive to mount singly at present, being restricted for economy reasons to strips of devices. Elastomeric members are also becoming more widespread in use as a switching member in telephone key pads. The present invention provides a simple and inexpensive mounting of LCD devices individually, in association with switching keys. The key is formed by one protrusion on the elastomeric member. The LCD device is mounted in a recess on the top of another protrusion associated with the key protrusion. Conductive paths through the device mounting protrusion connect at their bottom ends with conductive paths and at the top ends with contacts on the LCD device. -i-
