ABSTRACT:
A device for connection to telephone system modules for testing of telephone lines associated with the modules. The device includes structure formed of multiple parts fitted together, wherein a top part provides a cover providing access to telephone terminals for testing characteristics of a telephone line. The top part has a central orifice for receiving a manually operated, rotationally disposed control device, the control device engaging tabs associated with metallic parts which are disposed in a reverse symmetrical arrangement in one of the multiple parts. The tabs impart straight line movement to the metallic parts in response to rotational operation of the control device to cause the parts to engage the telephone terminals.
