Abstract

28,657. Meyer Akt.-Ges., P., and K³hnel, E. Dec. 9. Electro-magnetic switches and interrupters. - A loose armature d dips into two mercury-cups c formed in an hermetically closed tube b, and is acted upon by the electro - magnet a which is energized by a winding e, which may be in series with the circuit to be broken. The switch may be used, acting as an interrupter, to give an indication of excessive current in a circuit, or as a relay.
