Definitions

  • the present invention has for its object an automatic time switch for electric applications and notably for signalling circuits; said time switch operates electrically and makes it possible to maintain a mechanically controlled current impulse for a short yet variable period of time.
  • a stud G Arranged close to said stud F is a stud G on a flexible strip A connected with the working circuit M and the position of which can be adjusted e. g. with the aid of an eccentric H.
  • the bimetallic strip is raised by the action of the heat much quicker than it cools down, so that any actuation of the hand lever in the one or the other direction before the working time is completely elapsed will result in a new impulse of current being sent through the heating resistance, so that the time switch is re-started for a new full period of operation.
