[Also in Division H1] Contact jacks 9 connected via cables 13 to the secondary circuit of a transformer are short circuited when apparatus such as plug-in relay 20 is disconnected by a conductive body 4 spring loaded within aperture 3 in insulating body 2. The lengths of pin 22 on relay 20 and guide pin 14 on body 4 are such that on insertion plugs 21 make good connection with contacts 9 before body 4 is pressed so far to the right that the short-circuit connection is broken.
