Definitions
- the operating device 16 consists essentially of a horizontally disposed profiled lever 23 provided laterally with a pair of vertical profiled lateral plates indicated overall by 24, said plates being provided at one end with slots 25 in sliding engagement with a pin 26. Said lateral plates 24 are also provided with stop teeth 45 and shaped guide portions 46 and 47 disposed on opposite sides of the stop teeth.
- a pair of springs 28 are fixed between the pin 26 and a crosspiece 27, a further spring 29 being provided centrally between the springs 28 and fixed to the crosspiece 27 and to a fixed point 30.
- Figure 1 shows the switch of the invention when open, with the movable member 31 and the loading element 34 shifted towards the profiled portion 46; the loading spring 39 is completely unloaded and the lever 23 is completely raised from the coil 17 and its plunger 41.
