Abstract

191,879. Graham, E. A. Nov. 4, 1921. Regularing - switches. -A resistance coil b is wound in helical grooves a<3> on an insulating body a and has each end and one or more tappings connected to contacts d, d<1>, d<2>. A spindle f car. ries a contact bridge e that bears on the contacts d &c., and on another contact c which forms one terminal of the switch, the other terminal being connected to the contact d<2>. Such a switch may be used for dimming motor-vehicle headlights.
