Abstract

Switch mechanism, of alternate action, comprising a frame, a ratchet wheel, toothed and rotatably mounted on said frame, a trigger member, rigid, having an engaging end with the ratchet wheel, laterally offset from the axle of rubbing said ratchet wheel, trigger member which at the other end is freely pivoted in said frame, for transverse movement with respect to said frame and said ratchet wheel between a normal position and a laterally displaced position; spring means exerting an elastic force on said trigger member along an inclined direction, to urge said trigger member to a pivoted position out of engagement with said ratchet wheel and up to said normal lateral position; and actuating means, hand-operated, connectable with said trigger member between the two ends of the latter to cause it to mesh with said ratchet wheel against the action of said spring means and rotate ratchet wheel in the distance of a tooth, said spring means returning the said trigger member to its pivoted position out of engagement with said ratchet wheel and in said normal position, when said actuating element is released, disengagement of said member being allowed to occur. trigger of the teeth of said ratchet wheel during the return movement of said trigger member by the transverse movement of said trigger member to temporarily assume its position displaced laterally against the action of said spring members.
