Abstract

511,653. Switch contacts. PRENTICE, H. B., and FIELDING, J. G. Sept. 1, 1938, No. 25555. [Class 38 (v)] Switch contacts comprise a pair of plates 1 which are connected by a flexible conductor 4 and have pivotal engagement with recesses 2 of an insulating carrier 3. A bowed spring 7 biasses the contacts downwards and is held in position by engaging a projection 8 on a cover part 5 of carrier 3. This construction permits the easy removal of the contacts from the carrier after removing the spring 7. The fixed contacts 9 comprise bent plates having slotted ends for engagement with fixing bolts 10 thus allowing easy removal after slackening the nuts. When the carrier 3 moves downwards the tips of the contacts 1 engage the tips of contacts 9. Further movement causes contacts 1 to roll on contacts 9 so that the final point of engagement is near the bend of contacts 9. This means that the loadcarrying part of both contacts is not used for making or breaking the .circuit and so is not damaged by sparking.
