Abstract
The invention relate to a position signaling layout for a motor drive which also serves to activate an on-load tap changer, an off-circuit tap changer or a plunger core coil. Position signaling devices of this kind detect the position at a given time of the on-load tap changer or similar and transmit this information in the form of an electric signal. According to the invention, the device consists essentially of a board on which there are fixed signaling contacts and a pivoted cam disc which connects said fixed contacts electrically and links them to a terminal lead via a spring operated switch, activating the spring operated switch by means of its front cam contour.
