Abstract
564,491. Mercury switches. O'BRIEN, J. F. March 26, 1943, No. 4925. Convention date, March 26, 1942. Addition to 544,435. [Class 38 (v)] In a mercury switch according to the parent Specification, the reciprocable means 41 operated by a push-button is adapted by completing a stroke in one direction to operate the driving gear to rotate the switch a predetermined but partial amount, as by movement of the hook 55 and a pin 40 to the right, and only to finish the rotation of the switch into open or closed position on release of the push-button and the consequent return movement, to the left, of the means 41, whereupon the nose 58 engages others of the pins 40 to complete the movement.
