  • Patent number: 5704467
    Abstract: A keypad is provided wherein the keys are sealingly mounted in keyholes provided in a housing by means of a key mount which centers each key and seals the space between each key and the edge of its keyhole. The key mount also provides an electrical contact which is brought into engagement with underlying circuitry in response to depression of a key. The key mount also resiliently mounts the key within the keyhole so after depression of the key the key mount returns the key to its initial position in which the contact is spaced from the circuitry.
