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

In the Fig. 1 and 2 are components of a wireless adapter shown in two "exploded views". The plastic housing (adapter housing) of the wireless adapter consists of a bottom plate 1 and a cover 6, wherein these two housing parts are preferably connected to each other by means of a latching connection. For this purpose, a plurality of formed on the bottom plate 1 locking pin 2 can be seen, which engage in corresponding recesses (not shown) directed to the housing interior portions of the side surfaces of the lid 6.

In the adapter housing is a circuit board 12, wherein a locking of the circuit board 12 within the housing by a plurality of integrally formed on the bottom plate 1 holding pin 5, which engage in corresponding holes 15 of the circuit board 12. The printed circuit board 12 has a bore 13 which serves for the rotatable mounting of a cam disk 20. The cam disk 20 has for this purpose bottom sliding sections 23 (guide pin), which slide along the lateral boundary surfaces of the bore 13. The cam plate 20 is provided with a central recess 21 corresponding to the square profile of a handle actuating bolt (see paragraph 28 in FIG Fig. 3 ) Mistake. The (otherwise homogeneous) cam 20 has a lateral cam surface 22 which has at least one indentation or elevation, so as to act on an actuating pin 19 at least one attached to the circuit board 12 microswitch 18 (possibly additional 32).

Preferably, the cam surface 22 is formed symmetrically, as in Fig. 4 is shown, where Fig. 4 by way of example a view of a possible formation of the cam surface 22 of the cam disc 20 with a recess 31 in the (middle) portion of the cam surface 22 shows.

Detects the actuating pin 19 of a microswitch 18, the recess 31 (see position A in Figure 4 ), the window or door handle is in the "closed" position. Detects the actuating pin 19 of the microswitch 18 no indentation (see position B in Fig. 4 ), the window or door handle is in the "open" position. In the Fig. 4 shown symmetrical design of the cam surface has the advantage that the wireless adapter is universally usable for windows and doors with right stop or left stop. Of course, alternatively, a symmetrical configuration of the cam surface 22 with a (middle) elevation instead of a (middle) indentation realized.

By a corresponding design of the recesses or elevations on the cam surface can also several (especially two) actuating pins 19 of several (especially two) micro-switches 18, 32 (see Fig. 5-7 ) are actuated, so that several different states (in particular three), z. Normally, the window or door handle is rotated 90 ° from a central position downwards between the positions "open" and "closed" and a rotation of the window or door handle. or door handle 90 ° from a middle position upwards between the positions "open" and "tilted".

An attached to the circuit board 12 transmitter 24 including radio transmitter module converts depending on the position of the cam 20 and thus the window or door handle (see paragraph 27 in Fig. 3 ) of the at least one microswitch 18 (possibly 32) generated electrical signals in radio signals, which radiated via an antenna mounted on the circuit board 25 to an external, serving to evaluate the window or door handle position radio receiver of a central station (for example, a wireless alarm system) to wirelessly signal that the sash or door leaf is currently open or closed (or tilted). To one Position change (movement of the handle from open to closed and vice versa) also display directly on the wireless adapter, a light-emitting diode may be mounted on the circuit board 12, wherein the cover 6 of the adapter housing is provided with an opening to the current position on the basis of the color LED (eg LED lights up red: door or window open / LED lights up green: door or window closed).

For powering the electrical / electronic components of the wireless adapter (see paragraph 26 in Fig. 3 ) is preferably used in a battery receiving tray 9 insertable battery 11 (or accumulator), wherein the battery receiving compartment 9 by means of a battery cover 10 is closed. The battery can be changed from the outside in a very simple way. In order to achieve a battery receiving compartment 9 of suitable size, the circuit board 12 is provided with a recess 14. For contacting the battery poles, two battery contact lugs 16, 17 are mounted on both sides of the recess 14 on the circuit board 12. In order to indicate a required battery replacement (or a required charging of a battery), a light emitting diode may be mounted on the circuit board 12, wherein the lid 6 of the adapter housing is provided with an opening to the current light status (LED flashes: Change battery / LED off: Battery capacity is still sufficient) to recognize this LED.

Of course, for the passage of the handle actuating bolt (see paragraph 28 in Fig. 3 ) Both the cover 6 and the bottom plate 1 with holes 7 and 3, respectively. To attach the radio adapter to a door leaf or window frame, both the lid 6 and the bottom plate 1 are provided with holes 8 and 4, respectively, through which handle fixing screws can be guided.

In Fig. 3 is a mounted wireless adapter shown. As can be seen, the handle actuating pin 28 engages in a closure mechanism 30 of a door leaf 29. A rotation of the window or door handle 27 is detected by the mounted between the handle 27 and door 29 radio adapter 26 and reported by radio signal.
