ABSTRACT:
A telephone handset that has a light bulb disposed on it has a special switch that allows the light to automatically illuminate upon using the phone. The switch changes from an open position to a closed one upon a change in the orientation of gravity. One embodiment of the switch includes a hollow chamber having two separate contact plates disposed at one end and a freely sliding conductive manner that comes into contact with the contacts upon picking up the phone. A second switch embodiment includes three parallel pins with a central one the pins having a hanging pivoting member that serves to contact one of the other pins upon a change in gravitational orientation. Also included is a removable socket member to facilitate replacement of the bulb.
