• H01H 53/01 Details
• H01H 53/02 Electrodynamic relays, i.e. relays in which the interaction is between two current-carrying conductors
• H01H 53/06 Magnetodynamic relays, i.e. relays in which the magnetic field is produced by a permanent magnet
• H01H 53/08 wherein a mercury contact constitutes the current-carrying conductor
• H01H 53/1 Induction relays, i.e. relays in which the interaction is between a magnetic field and current induced thereby in a conductor
• H01H 53/14 Contacts actuated by an electric motor through fluid-pressure transmission, e.g. using a motor-driven pump
