  • Methods of and apparatus for protecting circuit elements from electrostatic discharges
    Patent number: 4580188
    Abstract: The continuity of a ground strap (16) is tested by pushing down on a switch activating toggle lever (37). The toggle lever is conductive, is isolated from ground and is coupled to a signal input terminal of a test circuit module (14). Thus, when the hand of the operator touches the toggle lever to activate the test circuit module (14), the resistive path through the operator and the ground strap (16) is coupled into the test circuit as the input-terminal-to-ground resistor of a voltage divider circuit. A resulting voltage at the toggle lever causes an indication by lighting either indicator (33) or indicator (34) whether the operator is properly coupled to ground.
