Abstract

Improvements in control apparatus, provided with a magnetic relay device, characterized by a magnetic circuit comprising two separable parts, one of which is arranged for connection to actuating means that can act to cause the separable parts to separate, and means dependent on the change in the magnetic flux of the magnetic circuit when the parts are separated, prepared to drive indicating devices or others.
