ABSTRACT:
An elongate piezoelectric plastic is embodied in a flexible casement to serve as a switching element for electrically motivated apparatus especially as used by disabled persons. The ends of the switch are adhered to portions of a human body that may be moved relatively to each other for activation. The plastic piezoelectric element is of a particular compound nature to enhance signal strength and of a particular configuration to prevent noise and shorting at the peripheral edges. Ancillary electrical circuitry enhances signal strength, logically evaluates multiple signals and annunciates those signals audibly or electrically for relay activated switching of other devices.
