Definitions
- the invention relates to a switch insert for rotary switch according to the preamble of Patent claim 1.
- Such a switch insert is disclosed for example in DE 28 24 584 A1 and There already has a contact plate with Schleifersegmenten and connector leads for power supply and wiring and a switch grinder on the rotary switch can be adjusted. Overall, however, results for this construction a relatively high height, the use of this rotary switch, for example in vehicle uprights, does not allow.
- this switch is not suitable for today's requirements, i. higher Current loads that can occur when switching on and off blower motors, Window heating etc.
- Fig. 1 shows a section through an operating element 1 for heating, air conditioning and / or ventilation systems of motor vehicles from which the arrangement of a switch insert 2 and a rotary switch 3 can be removed.
- the switch insert 2 consists of a contact plate 4 with Schleifersegmenten 5 and Plug connection conductors 6 for energizing and wiring and a switch grinder 7, which can be adjusted by the rotary switch 3.
- Schleifersegmente 5 within a plastic plate 8 so arranged are that they contacted from the other side by another switch grinder 9 can be, whose contacts 10 mirror images of the contacts 11 of the first Switch grinder 7 are arranged, wherein the further switch grinder 9 guide lugs 12, which by guide recesses 13 of the first switch grinder. 7 protrude and record in a retaining slot 14, a leaf spring 15, on the other hand under resilient tension on the contacts 11 facing away from the surface first switch grinder 7 is supported and thereby the contacts 10, 11 both switch grinder 7, 9 loaded against the grinder segments 5.
- the switch insert 2 is arranged on a bearing journal 16, which at the same time the rotary switch 3 stores, which with a driver lug 17 in a guide recess 18 of the Switch insert 2 protrudes and the switch grinder 7, 9 carries.
- the leaf spring 15th has two resilient latching arms 19 which cooperate with latching steps 20 of the journal 16 and the locking of the contacts 10, 11 of the switch grinder 7, 9 with respect to cause the Schleifersegmente 5.
- Fig. 2 shows the switch insert 2 as a single part with the contact plate 4, as a plastic plate 8 is executed, in which the grinder segments 5 against each other electrically isolated are embedded.
- the wiper segments 5 are connected to the plug connection conductors 6.
- Fig. 3 shows in exploded view the items plastic plate 8, the two switch grinder 7.9 and the leaf spring 15.
- the switch grinder 9 shows the management approaches 12 with the retaining slots 14 for the leaf spring 15th
- Switch grinder 7 shows the guide recesses 13, with the guide lugs 12th of the switch grinder 9-cooperate.
- Leaf spring 15 shows Auflageabbiegonne 21, facing away from the contacts 11 Surface of the Wegerschleiffers 7 come to rest and the contacts 10, 11 against the Load grinder segments 5.
- the latching arms 19 are by bent projections of the leaf spring 15 formed.
- one of the slider segments 5 as a zero position signaling contact 22 is executed, so that the zero position, for example, an electronic control unit or a security circuit can be identified.
