Abstract
A tester is provided for a control yoke of an oil-filled electrical power switch. The tester can be easily and safely used by a line crew member. The tester is connected to the yoke which carries electrical signals to control the position of the switch. Control signals are then furnished to the yoke in the usual manner. Indicators on the tester identify whether the yoke or the switch is the source of the problem.
