Abstract
A make before break switch having two opposed fixed contacts separately closed by a pivotal contact lever. A center fixed contact supports the lever for movement both pivotally and vertically so that the contact lever closes on both said two fixed contacts in an intermediate position. A conventional actuator means and spring biasing means controls the contact lever as it is so moved, and a secondary biasing means is provided below the lever to allow the make before break action as the actuating means moves through its intermediate position.
