Abstract
503,282. Electrical meters. WATSON, T., and ENGLISH, C. J. April 19, 1938, No. 11687. [Class 37] [Also in Group XIX] In an electrical indicating instrument having a switch by which the instrument can be selectively connected to a number of measuring devices, a member indicating the measuring device in connection at any time is displayed through the window of the electrical indicating instrument, the switch and the indicating member being operated simultaneously by means external to the casing. The instrument may comprise a pointer a moving over a scale b and may be connected to any one of series of measuring devices by the turning of a switch knob d. The device in connection is indicated by a numeral on a drum operated by the switch knob d and exposed through an aperture i in the scale plate.
