Abstract
A switch has a first electrical terminal, a second electrical terminal spaced from the first electrical terminal and an elongate conductive switch blade for bridging the terminals. The switch blade has a first end portion pivotally connected with the first electrical terminal for movement of the switch blade between open and closed positions. The switch blade has a second end portion positioned adjacent the second electrical terminal when in the closed position. A plurality of elongate fingers are secured by spring loading to the second end portion of the switch blade. The fingers are arranged adjacent to each other along opposing sides of the second end portion to form an open jaw structure that extends from the second end portion of the switch blade and makes wiping electrical contact with the second electrical terminal as the switch blade is moved into the closed position.
