Definitions
- the invention relates to an electrical contact switch, in particular microswitches for motor vehicles, with a connecting contacts and receiving a contact element Housing on which an actuator with a Switch plunger is mounted, which acts on the contact element, the at least one supported on a connection contact Support leg and at least one of the actuating element returning, as well as approximately perpendicular to it contacts has pressurizing contact leg.
- the contact element is one point Connection contact pivots, results between the other Terminal contact and the contact element a touch contact, the slightly dirty. Therefore, it is required a very to provide high quality contact material pairing. It is very costly, because on the one hand as contact material usually Silver is used and on the other hand at least per contact part an additional step to apply the contact is required.
- contact material usually Silver is used and on the other hand at least per contact part an additional step to apply the contact is required.
- the contact element on the one hand with the Contact towards the terminal contact and the other the bearing is positioned. Until the final assembly then the case must be handled very carefully, because otherwise the contact element from its correct position slips, which would result in an assembly error. The careful trading is very time consuming. By the nature of the Contact assignment can only be closed by one current path be, which means only a limited use of the contact switch is possible.
- DE 31 10 971 C2 discloses an electrical one Contact switch, in which the contact element is also a Is stamped part.
- the contact leg slides on the housing or on the connection contacts along and causes self-cleaning the contact connection.
- the resilient orientation of the contact element runs to the walls of the housing, i.e. only in one Direction.
- an additional spring element is therefore required. So that the contact element has a sufficiently soft spring force owns, the legs must be long. These legs extend itself in the direction of actuation, causing the contact switch builds big. Furthermore, the contact switch can only switch a circuit, resulting in limited use leads.
- the invention has for its object an electrical To create contact switches of the type mentioned by an inexpensive, versatile and small design high quality is guaranteed.
- the Contact element a double-acting, one-piece from one electrically conductive round wire existing torsion spring is the center of the support leg from two adjacent bent wire pieces, to which each a half connected via a helix present in the bending radius, the in an upward and outward contact leg transforms.
- one is attached to each piece of wire on the support leg one and a half helix to the spring action of the torsion spring to improve.
- each contact leg has at its free end an inward bend.
- the bending causes a clean and hook-free gliding on the walls of the housing, at the contacts and at the transitions between the contacts and the housing.
- the contact leg bent in a V-shape, and the support leg supports itself on a floor inside the housing at least partially from the connection contact, and the Contact leg protrudes in the direction of an opposite of the floor Housing opening, the contact leg one to about vertical bias.
- This allows the split with the contact leg to achieve effects become. For one, this is the restoring force for that Actuator facing the bottom of the case is and in the operation of the actuator enlarged. This causes when the actuator is pressed also a higher contact pressure of the support leg on the existing contact in the bottom of the housing, whereby the electrical connection is improved.
- a contact force of the contact leg on the connection contacts achieved what by the vertical bias of the Contact leg is ensured.
- the support leg and are preferred the contact leg of the contact element over a ratio connected to each other to form a large bending radius.
- the housing from the bottom with subsequent, perpendicular to it Walls, and the contacts in the floor and at least recessed into a wall, at least in the Walls of the connection contacts are embedded at the same level.
- the housing can then be easily manufactured as a molded part, the recesses during the production of the molded part for the contacts in the same operation can be.
- the same level with the surface of the walls Ensure connection contacts embedded in the housing a transition not felt by the shift feeling.

- the actuating element a pressure tappet, which is attached to the housing in a Lid is inserted in a lid hole, wherein the pressure ram comes into contact with the inside wall of the lid, Switch plunger wider in cross section than the cover bore having.
- the im Cross section rectangular switch plunger on its the contact element facing switch cap rounded, the switch cap to the walls of the housing on which the switching plunger is moved past is slightly inclined, whereby between the switch cap and the corresponding wall of the housing Angle that is less than 90 °.
- the contact leg of the contact element following a certain path on one in the wall of the Housing recessed contact to lie. There must always, even after wear of one of the contact elements, there is sufficient contact pressure. For this Basically, the contact leg is created via the slope of the switch cap pushed slightly outwards.
- the operating force applied to the actuator should be as low as possible. Because by this operating force but also influence the contact force between the Support leg of the contact element and in the bottom of the housing recessed connector contact is preferred the contact element with its support leg on the im Welded on the bottom of the housing existing contact. It is also achieved in that the contact element after the Inserting and welding in the housing is tight and not more falls out.
- the housing can thus be on the line from the machine be equipped and in the further production process as Flow in bulk material.
- connection contacts in one wall several in the swivel range of the Contact element consecutive connection contacts are.

- the contact element 5 is made of an electrically conductive round wire manufactured. About one in relation to the material thickness of the contact element 5 is very large bending radius 43 Support leg 11 connected to the contact leg 12. The Material with a bending radius of 43 runs in the form of a spiral 14, with one contact leg from each of the two ends of the helix 14 12 goes tangentially. In the middle of the helix 14 the support leg 11 is worked out. To do this runs Wire piece 15 also tangentially out of the coil 14 and that is offset by approximately 180 degrees to the contact leg 12. The length of the wire piece 15 is almost up to one the opposite wall 3.4 molded seat ramp 16 there bent over 180 degrees and plunges tangentially back into the helix 14 a.
- Support leg 11 and the contact leg 12 lie approx. 1 1 ⁇ 2 helix 14.
- the seat ramp formed on the wall 3.4 16 already ensures when inserting the contact element 5 the approximate positioning in the housing 1.
- Each contact leg 12 carries on his free end of a bend directed into the interior of the housing 1 17.
- Radius in front of the walls 3.1 or 3.2 whereby a clean, hook-free sliding of the contact leg 12 on the respective wall 3.1 or 3.2, or on the connection contacts 4w or the transitions in between goes.
