Complex button

The invention refers to a complex button with four different electric signal outputs generated by means of a single activating knob, used in electrical control equipment that is especially designed for the aviation industry. According to the invention, the complex button is made up of a body (6) on which four micro-switches (9 and 35) are positioned and fixed, and in which a main shaft (3) and a secondary shaft (15) are connected by bearings, one after the other. The main shaft (3) activates the two micro-switches (9) corresponding to the press and pull functions by means of two collar sleeves (8), whilst on the secondary shaft (15) a wheel (21) is fixed with the front toothing activating, via a lever system (19 and 20), the other two micro-switches (35) that correspond to the unlimited rotation functions, to the right or to the left, by twenty electrical impulses for every 360 degrees, the rotating motion is induced by a coupling system from the main shaft (3), which is actuated with the help of an activating knob (1).
