  • Deformable membrane keypad assembly for public telephones
    Patent number: 4862499
    Abstract: A telephone keypad assembly including a one-piece deformable membrane for sealing the keypad assembly from the environment. The deformable membrane has an upper surface for mating with keypad pushbuttons and a keypad pushbutton housing unit, and a lower surface including a contact actuator for making contact with electrical switch contacts. The membrane forms raised areas or domes which bias the keypad pushbuttons and biasingly resists movement of the contact actuator toward the electrical contacts. The keypad assembly including switch contacts is protected from moisture, dust and other corrosive elements by the seal formed between the housing unit and the deformable membrane.
