The invention will be described below with reference to the embodiments illustrated in the drawings explained. Show it:

1 . 2 Components of a radio adapter in two "exploded views"

3 a mounted wireless adapter,

4 a view of a possible formation of the cam surface of the cam disc,

5 . 6 . 7 a variant with two micro-switches for additional detection of the position "tilted".

In the 1 and 2 components of a wireless adapter are shown in two "exploded views." The plastic housing (adapter housing) of the wireless adapter consists of a base plate 1 and a lid 6 , These two housing parts are preferably connected to each other by means of a latching connection. For this several are on the bottom plate 1 molded locking pin 2 to be seen, which in corresponding recesses (not shown) facing the housing interior portions of the side surfaces of the lid 6 intervention.

The adapter housing contains a printed circuit board 12 , wherein a locking of the circuit board 12 within the housing by several on the bottom plate 1 molded retaining pins 5 takes place, which in corresponding holes 15 the circuit board 12 intervention. The circuit board 12 has a hole 13 on which for the rotatable mounting of a cam disc 20 serves. The cam disk 20 has for this purpose bottom sliding sections 23 (Sliding peg), which along the lateral boundary surfaces of the bore 13 slide. The cam disk 20 is with a central recess 21 according to the square profile of a handle-actuating bolt (see paragraph 28 in 3 ) Mistake. The (otherwise homogeneous) cam disc 20 has a lateral cam surface 22 on, which has at least one indentation or elevation, to such an actuating pin 19 at least one on the circuit board 12 attached microswitch 18 (if necessary in addition 32 ).
