Abstract

545,488. Tumbler switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., and MORGAN, R. W. April 3, 1941, No. 4458. [Class 38 (v)] In an "intermediate" tumbler switch, blade contacts c, c<SP>1</SP>, which are connected to terminals 2, 4 and normally engage contacts d<SP>2</SP>, d' connected respectively to terminals 3, 1 so as to establish a diagonal connection of the terminals are depressible by the dolly in its other position out of such. engagement, two contacts on the dolly then engaging the blade contacts c, c<SP>1</SP> to establish the other connection of the terminals. The two contacts on the.dolly are respectively connected to brackets k, k<SP>1</SP> connected to the terminals 1, 3 so that in this position of the switch, terminal 2 is connected to 1 and 4 to 3.
