摘要:
A weatherproof electronic keypad includes a molded plastic housing, a plurality of transducers attached to the inside surface of the front wall of the housing, an electronic circuit mounted within the housing and connected to the transducers, and a graphics overlay removably affixed to the outside surface of the front wall of the housing. The front wall and overlay are sufficiently flexible that finger pressure applied to the overlay results in enough deformation of the front wall to activate the transducer underlying that portion of the inside surface. The overlay contains indicia which identify the location and function of the transducers. The overlay need not be attached to the housing as a part of manufacturing the keypad, but rather can be added in situ as part of installation of the keypad. This enables customized selection of a particular overlay in accordance with aesthetic and/or functional considerations, as well as replacement of the overlay in the field if necessary.
