Large push button. -. ^: . " ^: -""- .. - ■

The! Price increase refers to a large, in particular, elongated pushbutton for actuation "of an electrical Contact set whose actuating plunger is under spring force and holds the key body in its rest position .. -? "■.

Large-area pushbuttons are mainly used in cases. . uses where the key has a relatively large amount of space -. claiming lettering. When the- ' ^: like pushbuttons step lightly. Clamps. And thereby. ¹ causes signs of wear and tear if the operator does not focus precisely on the. Button presses. . \. . ; .

The! Inflation is therefore based on the task - a to design large-scale pushbutton of the aforementioned Jkrt so that a jam-free and wear-free actuation of the Contact set is guaranteed even if the operator presses the button strongly off-center. .- ^ - .- / - "~ ■" '■

This object is achieved according to the invention in that on the underside of the. fcippbewegli.ch stored on all sides .: ■.
