V / ipp switch

The invention relates to a pulse switch, in particular fir Motor vehicles from a pressure plate held in a housing with a pressure bar acting on a contactor as well as one, am G-ehäuseboden arranged mating contact.

In motor vehicle construction, so-called "Te ^ poTjat" devices have recently been found, ie G-esch.vindigkeitsbbegrenzungseinlagen _λ γ, oi with the help of which the motor speed is limited to a preset maximum speed corresponding V / ert. These investments are pulse-connected devices, ie uil · institutions which also means a üurzen ochaltiicpulses in 3etrieb and through - switching pulse are again taken out of service - acting in the opposite direction. They are operated with the help of a pulse or signal switch that is briefly depressed

and immediately return to their central dead position after actuation.

Here it is generally felt to be disadvantageous that for Switching the system two separate switches are required and that the driver when lowering the switch is not immediately receives a perceptible indication of the impulse, i.e. about it, that the speed limitation device is in or out of function.

The aim of the present invention is accordingly to provide a switch for this purpose, separated with the aid of two switching pulses may be palpated whilst ensuring a separation of functions, that is secure exclusion of accidental simultaneous connection of both punctures and the halt indication triggers upon actuation of a perceptible S _c. The invention consists in leaving the contactor with a flat edder plate provided with a central bore for the passage of a fastening screw and indentations embossed on both sides, which is arranged on both sides by means of a contact point between the indentation and the contact point. Support web is prestressed under bending.

If encoder embossed M _u ldenvertiefungen in conjunction with the support between the trough depressions and the pressure and contact points a sudden jumping of the contactor enters a bending position, thereby on the one hand ensures that the switch reaches the contact position, and on the other hand caused a clearly perceptible shift crack . After the] triggering of the click when the pressure is applied and when the switch springs back after the application of pressure, it is thus ensured and the driver can see that the device has been switched on. Furthermore, due to the web support of the contactor and the resulting tension conditions in the spring tongues of the contactor, an unintentional simultaneous switching of both switching functions is already largely eliminated. It can be completely prevented in that the pressure plate is rotatably mounted in an axis running perpendicular to the contacts.

The invention is illustrated by way of example in the 3 drawings.

In the drawing, the switch housing is denoted by 1, into which a switch base 2 is clipped by means of locking cams 3. 4 with the contactor is referred to, which - see Fig. 3 of a flat one with an aittigen bore 5 and on both sides embossed Iluldenveriefungen 6 provided double spring plates is formed. The contactor 4 is - FIG. 1 - by means of a screw 7 against the switch base 2 via two on the switch base arranged support webs d screwed, which the contactor on a located between the hollow 6 and the contact points 9 Support position so that the contactors are individually biased towards the outside. In the drawing are still with 10 the - electrically separated - counter contact points, with 11 the conductor plug-in terminals for the voltage connections and with 12 of the Referred to as ground connection.

The switch bottom is covered by the pressure plate 13, which is each provided with a pressure web 14 in the area of the contact points 9 and cit which the pressure plate resiliently on the spring pliers of the Kontaktjebecs; supports.
