- Degree of freedom of the pawl 5, as understood by a mechanical locking device As understood by a mechanical locking device.
- the mobility of the pawl 5 is to be limited in the degree of freedom, in particular completely blocked, in which the pawl 5 must be moved in order to obtain a triggering of the switching mechanism 2.

- the basic degrees of freedom of the pawl 5 remain preserved, but it will be a movement of the pawl 5, in particular a movement of the pawl 5, which could lead to a triggering of the switching mechanism 2, attenuated.
- vaping denotes in a concrete context that the pawl 5, at least during a correspondingly caused movement of the same, a force is applied, which reduces the amplitude of the movement of the pawl 5. In particular, such that as a result of such movements decay in time. It has been found that the pawl 5 is placed at said transition in significant vibration.
- vibrations are caused - as has been shown - in particular by the moving masses of the switching mechanism 2 and the at least one first switching contact 3, as well as their deceleration, which takes place, for example, by fixed stops in the region of the switching mechanism 2.
- the pulses generated thereby lead to a good part to said vibrations of the switching mechanism. 2

It should be noted that it is a spring 8 to the real mechanical component is spring 8, and not an idealized spring. A real spring 8 is therefore not only an energy storage, but always a damper, which leads to a subsidence of the movement under the action of the spring 8.
- the design as a spring 8 allows a very simple production and low tolerances over long manufacturing processes.
- the spring 8 is formed as a leaf spring 9, as is also provided in the embodiment according to FIGS. 2 to 9.

- the spring 8 can also be provided to form the spring 8 of a polymer material.
- the spring 8 has a flat spring characteristic. It can thereby be achieved that the force exerted by the spring 8 on the pawl is substantially constant over wide areas. It is preferably provided that the force which is applied by the spring 8 on the pawl 5 is small in order not to damage the pawl 5.
- the securing device 7 is designed as a polymer element, in particular as a polymer foam element.
- the securing device 7 can be provided to secure the securing device 7 to the pawl 5, whereby the possibility is given to use the corresponding securing device 7 for influencing the center of gravity and / or the moment of inertia of the pawl 5 and thus also for influencing the tripping behavior.
- the securing device 7 is designed such that it is objected to in the first position by the shift lever 4. As a result, the triggering operation is not influenced by the securing device 7.
- the securing device 7 is attached to the shift lever 4. This can be a simple retrofit of an existing and mature construction will be possible. As a result, in particular, the pawl 5 can be taken over unchanged in terms of their construction. An advantageous in practice and suitable latch construction may turn out to be a lengthy evolutionary process, so that when further use of the pawl 5 considerable development effort can be saved.
- the securing device 7 is designed such that it is objected to in the first position of the pawl 5.
- Securing device 7 is not affected. As a result, we do not affect the entire triggering system and behavior of an existing and adapted construction of a corresponding switching device 1, so no new decrease desselbigen is required. As a result, without any changes or influences on the tripping behavior of a switching device 1, its false-tripping rate can be considerably reduced.
- Fig. 8 shows a shift lever 4 of the particularly preferred latching mechanism 2, to which a securing device 7 designed as a leaf spring 9 is attached.
- the corresponding leaf spring 9 in this case has a connection region 45, to which it is connected to the shift lever 4, and a contact region 46, which is provided for contact with the pawl 5.
- Fig. 9 shows a corresponding leaf spring 9 in a separate representation.
- the securing device 7 as a leaf spring 9 is further provided in particular that in the second position, only the contact region 46 of the leaf spring 9 is in contact with the pawl 5.
- the contact portion 46 contacts a contact pin 47 of the pawl 5, which contact pin 47 is disposed in the region of the stop edge 41 of the pawl 5.
- Fig. 6 shows approximately the corresponding state.
- the further region of the pawl 5 can be kept free of stress, or occur through the securing means 7 no additional stresses in the pawl 5, which would additionally burden them.
- the subject invention therefore relates in summary to a switching device 1 having at least a first movable switching contact 3 and a switching mechanism 2, which has a pivotally mounted shift lever 4, a pawl 5 and a Verklinkungsstelle 6, and which is at least indirectly connected to the first switching contact 3 to the To control movement, wherein the switch contacts 3 are separated in a first position of the shift lever 4 and the pawl 5 is disengaged from the Verklinkungsstelle 6, in a second position of the shift lever 4, the switch contacts 3 are separated and the pawl 5 at least indirectly at the Verklinkungsstelle 5 is latched, and in a third position of the shift lever 4, the switch contacts 3 are closed and the latch 5 is latched at the Verklinkungsstelle 6 at least indirectly, wherein the switching device 1 has at least one securing device 7 for securing the at least indirect latching of the pawl 5 with the
