Abstract

An actuating apparatus having a signal transmitter and a mechanical operating element, wherein the mechanical operating element includes a first position that is stable over time and a second position that is stable over time, wherein the mechanical operating element, in the case of a movement from the first position that is stable over time into the second position that is stable over time, actuates the signal transmitter, and wherein the signal transmitter, upon actuation, causes a first signal change followed by a second signal change of an output signal, and an evaluation circuit detects an actuation of the mechanical operating element based on the first signal change and the second signal change.

First claim

1 . An actuating apparatus, comprising:
a signal transmitter that transmits an output signal; and a mechanical operating element, wherein the mechanical operating element comprises a first position that is stable over time and a second position that is stable over time, wherein the mechanical operating element actuates the signal transmitter in response to a movement from the first position to the second position, and wherein, in response to the actuation by the mechanical operating element, the signal transmitter performs a first signal change followed by a second signal change of the output signal, wherein the actuating apparatus further comprises:
an evaluation circuit that detects an actuation of the mechanical operating element based on the first signal change and the second signal change, wherein a temporal interval between the first signal change and the second signal change lies within a predetermined range, and
means for preventing actuation of the signal transmitter in response to the temporal interval being outside the predetermined range.

2 . The actuating apparatus of claim 1 , wherein the output signal is optical, electrical, magnetic or electromagnetic.

3 . The actuating apparatus of claim 1 , wherein the predetermined range lies within ±20% about the temporal interval.

4 . The actuating apparatus of claim 1 , wherein the mechanical operating element comprises an operating lever and that the prevention means comprise a mounting arrangement, a sleeve, a spring, a receiving arrangement , a roller wheel, a running track and an actuating cam, wherein the operating lever is mounted on the sleeve by the mounting arrangement, wherein the sleeve comprises the spring, wherein the spring is connected to the roller wheel by a receiving arrangement, wherein the roller wheel moves freely in the running track between the first position and the second position, wherein, during the transition from the first position to the second position, the roller wheel passes an actuating cam mounted on the running track.

5 . The actuating apparatus of claim 4 , further comprising an electrical jumper in a housing, wherein the electrical jumper in the housing comprises electrical contacts, and wherein the roller wheel is coupled to a release device by a mounting arrangement, wherein the release device is connected to the electrical jumper.

6 . The actuating apparatus of claim 5 , wherein, as the operating lever moves from the first position to the second position, the electrical jumper is closed at a peak point.

7 . The actuating apparatus of claim 1 , wherein the mechanical operating element comprises a toggle switch, wherein the toggle switch is connected to an actuating cam by a mounting arrangement, wherein the actuating cam actuates the signal transmitter.

8 . The actuating apparatus of claim 1 , wherein the mechanical operating element comprises a rotary switch.

9 . The actuating apparatus of claim 8 , wherein the rotary switch comprises a plurality of positions that are stable over time including the first and second positions.

10 . The actuating apparatus of claim 9 , wherein the rotary switch comprises a profiled carrier that includes a radial cam profile or an axial cam profile, wherein the radial cam profile or the axial cam profile comprises a plurality of actuating cams.

11 . The actuating apparatus of claim 10 , further comprising a rotary wheel that rotates around an axis to cause movement of the rotary switch.

12 . The actuating apparatus of claim 11 , wherein the rotary switch performs a rotary movement, wherein the actuating cam of the radial cam profile or the actuating cam of the axial cam profile to actuate the signal transmitter during rotary movement.

13 . The actuating apparatus of claim 1 , wherein the signal transmitter comprises a membrane key or a micro button or a pressure button.

14 . An actuating apparatus, comprising:
a signal transmitter that outputs an output signal; a mechanical operating element, wherein the mechanical operating element comprises a first position that is stable over time and a second position that is stable over time, wherein the mechanical operating element actuates the signal transmitter in response to movement from the first position to the second position, and wherein the signal transmitter outputs a first signal change followed by a second signal change of the output signal in response to the actuation by the mechanical operating element; an evaluation circuit that detects actuation performed by the mechanical operating element based on the first signal change and the second signal change in response to a temporal interval between the first signal change and the second signal change being within a predetermined range, and an actuation cam arrangement that prevents actuation of the signal transmitter in response to the temporal interview being outside the predetermined range.

15 . The actuating apparatus of claim 14 , wherein the actuation cam arrangement comprises a mounting arrangement, a sleeve, a spring, a receiving arrangement , a roller wheel, a running track and an actuating cam, wherein the operating lever is mounted on the sleeve by the mounting arrangement, wherein the sleeve comprises the spring, wherein the spring is connected to the roller wheel by a receiving arrangement, wherein the roller wheel moves freely in the running track between the first position and the second position, wherein, during the transition from the first position to the second position, the roller wheel passes an actuating cam mounted on the running track.

16 . The actuating apparatus of claim 15 , further comprising an electrical jumper in a housing, wherein the electrical jumper in the housing comprises electrical contacts, and wherein the roller wheel is coupled to a release device by a mounting arrangement, wherein the release device is connected to the electrical jumper.

17 . The actuating apparatus of claim 16 , wherein, as the operating lever moves from the first position to the second position, the electrical jumper is closed at a peak point.
