ABSTRACT:
A photoflash lamp array having electrical terminals adapted to be connected to a camera socket. A spring member, in contact with one terminal, normally engages against a shoulder of another terminal, for shorting the terminals when the array is out of a socket. This reduces the possibility of accidental flashing of lamps in the array when a connector terminal is touched by a person or object having an electrical potential such as an electrostatic voltage charge. When the array is plugged into a socket, the socket lifts the spring member out of contact with the shoulder of the terminal and removes the short.
