Definitions

  • the time-switch device is of any known type comprising a relay which when it is energized, acts upon a movable armature which closes a contact, r and is then released after a predetermined time by 30 a clockwork movement.
  • the relay I0 remains energized as long as the clockwork mechanism has not released the armature for breaking the contact of the energizing circuit of the said relay.
  • a circuit is closed as follows: one of the poles of the source of current 42, wire 58, electromagnet 32, terminal 59 of the switch 34, mercury, terminal 53, wire 54, contact 38-39, winding 4
  • is energized by a current of the same direction as that considered for the position of the movable member 29, position indicated in the drawing.
  • the electromagnet 32 being energized, it restores the movable member 29 in the same position and everything is as it was initially.
