Abstract
A portable battery operated color television camera is provided with a switch system for use to preserve power while testing the camera and associated equipment or while engaged in standby operation. The switch system removes the power from two of the three pickup tubes in the camera, thereby reducing power consumption while allowing testing or standby operation in a black-and-white mode.
