  • said drive means comprise an electric motor connected with an outside source of electric energy and gear transmission means for transmitting rotary motion from said motor to said rotary switch means.
  • said contact member assembly is formed as an integral metal part comprising a first oblong resilient portion extending along the lower surface of the associated bar member and carrying on its outer surface and projecting therefrom said first contact member, a second oblong resilient portion extending along the upper surface of the associated bar member and carrying on its outer surface and projecting therefrom said second contact member, and a connecting portion connecting said first and second resilient portions, all of said portions being lodged in said recesses in such a manner that the whole assembly is held gnly through its resiliency in position on said bar mem- 6.
  • An arrangement as claimed in claim 6, including bumper means interposed between a stationary member of said box-like structure and a portion of said bar member for determining said normal position of rest thereof and for absorbing shocks when said bar member is returned by one of said return springs to said normal position.
  • said second plate member is composed of at least three superimposed layers of insulating material, the first of said layers being provided on its outside face with said second contact strips as printed circuit components, connections between a selected number of said second contact strips being arranged as printed circuit components along the rear surface of said first layer, the third one of said three layers being provided on its outer face with other connections between said selected number of said second contact strips and output lines connected to the same, respectively, in the form of printed circuit components, and the opposite face of said third layer being provided with further connections between said selected number of said second contact strips also in the form of printed circuit components.
  • said first operating means include electromagnet means arranged above said second plate member and having a plunger-type armature means movable in direction perpendicular to said second plate member between a normal upper position when said electromagnet means is unenergized, and a lower position when said electromagnet means is energized, said second plate member being suspended by spring means from said electromagnet means, said armature means being in abutting engagement with said second plate member for transferring the movements of said armature means to said second plate member, said electromagnet means being operatively connected with said business machine for being controlled by the latter depending upon the operational cycle thereof.
  • guide means are provided on said electrocooperating magnet means and on said second plate member for causing the latter to remain parallel with itself during its movement between said first position and said second position.
