Abstract (en)

[origin: US4503410A] A relay with a contact making independent from environmental conditions with two hermetically sealed contact pills is described. Each contact pill comprises a switching-over contact and a diaphragm made of electrically and magnetically conducting material which diaphragm is the movable member adhering on corresponding contact poles due to the magnetic flux caused by a permanent magnet and flowing through the core of a drive coil. To change the contact condition of the relay it is sufficient to produce a current pulse through the drive coil causing a control flux of a magnitude which exceeds that of the permanent magnet flux by a small amount only because the two fluxes add their strength when the change-over operation is initiated. Due to this adding the needed drive power is so small that a direct driving by TTL-circuits is possible. By other arrangements of the permanent magnet within the magnetic circuit monostable relays can also be realized.
