Reset device for indicator

摘要

A device for mechanically resetting, by means of a simple manipulation, an optional number of status indicators of the type consisting of an electromagnet with an iron core, a magnetizing winding and some form of permanently magnetized indicating disk capable of rotating through 180 DEG . The device comprises a rail made of a non-magnetic material and being formed so as to enable a desired number of indicators to be mounted side-by-side. The rail has such a profile as to enable a shuttle with a corresponding profile to be in engagement with and be guided by and slide on the rail in its longitudinal direction. The shuttle is provided with a permanent magnet as well as with a pole piece mounted so as to form, together with the core in the electromagnet of each indicator, a magnetic circuit when the shuttle is pushed over the respective indicator whereby the rotatable indicating disk is influenced and is reset to indicate the reset position.
