Abstract
The switch(es) are actuatable for making and breaking by a single rotary control cam in an impact manner. The cam has numerous radial edges, separated by identical peripheral sections. It is coupled to the switch by a leverage with two levers pivotally mounted on a fixed axis. Each lever is pressed against the cam profile by a lug driven by at least one elastic element. A connecting lever is hinged to the two levers at hinged point, differing from the fixed lever pivotal axes. Both lugs are of such configuration that the first one engages any cam edge shortly before the second one. The connecting lever carries a profile for sudden making or breaking of the switch, in relation to the engagement of the cam edges by the respective lugs of the levers, one providing the making and the other the breaking of the switch.
