Apparatus for enabling a keypad in response to antenna extension

摘要: An antenna switch is provided on a portable telecommunication instrument, such as cellular telephone, to enable operation of the keypad instrument when extended. In one arrangement, an comprises pair position sensing contacts disposed printed circuit board at where electrical continuity established between by electrically conductive member in extended position. The present invention solves problem inadvertent activation retracted. Thus, does not require closeable cover over prevent actuation instrument.
