Abstract

225,319. Midland Electric Manufacturing Co., Ltd., and Barber, W. L. Sept. 25, 1923. Contacts for knife blade, switches of the type comprising a block 5 having a longitudinal hole for receiving the lead and a separate or integral spring member 6 for pressing the blade firmly against the side of the block, have this spring member projecting above the block and terminating with a reduced end formed with an outwardly curved sparking lip. An opening 9 is formed in the lower portion of the spring member so that any unevenness of the blade 7 due to arcing with the tip of the spring 6 comes opposite this opening when the block is forced home and permits undamaged portions of the blade to be gripped.
