Definitions

  • the invention relates to an electrical switch in which a common contact body and a first and a second select contact body are provided in a housing.
  • a movable contactor which can be moved from outside the housing against spring force, establishes the electrically conductive connection between the common contact body and either the first or the second selection contact body.
  • a switch of this kind is for example from the DE 44 20 665 B4 known.
  • the contact surfaces of the first and second selective contact body are embedded in a wall of the switch housing.
  • the contactor is a slider which is provided with an actuator protruding from the housing.
  • a contact plate is embedded, which has a protruding contact finger.
  • the contactor is pressed into its one end position.
  • the helical spring produces the electrically conductive connection between the contact finger and the common contact body embedded in the housing.
  • the contact finger located on the contactor bears against the contact surface of the first selection contact body.
  • the contactor moves against the restoring force of the coil spring in its second end position, in which the contact finger bears against the contact surface of the second selection contact body.
  • Switches of this type are implemented in the miniature or subminiature range and serve to switching tasks in which a normally closed electrical contact is temporarily interrupted by mechanical action on the actuator, the conductive connection is made on a normally closed second contact.
  • Switches of this type are particularly suitable for position detection tasks in automatic manufacturing operations.
  • typical application areas can also be locking systems in the bodywork and interior areas of a motor vehicle as well as various position queries in household appliances or other mechanisms.
  • the contact finger of the contactor sliding from the contact of the first contact surface on the contact of the second contact surface, it is achieved that the switching behavior can be selectively influenced.
  • the influencing factors are mainly the sliding path of the contact finger, the size of the contact surfaces and their distance from each other. These influencing variables can be optimally matched to one another. Thus, for example, it is possible to maintain a strict separation between the two switching positions, or to allow an intermediate position in which both contact surfaces are in conductive contact with the contact finger. Further, in a switch of this type, the switching operation is reliably performed at a desired timing regardless of whether the operation is fast or slow from the outside.
  • a common contact body is selectively connected by a contactor with a first or a second election contact body.
  • the contactor is here an elastically deformable leaf spring, which receives a bias in the longitudinal direction by a tongue formed from her and thereby strives to assume a warped form.
  • the blade-shaped contactor engages with the entire width of its free end in the space of correspondingly shaped areas of the selector contact body. The surfaces of these areas are parallel to the surface of the sheet-shaped contactor.
  • the electrically conductive connection between the contactor and each one of the two selective contact body can be made.
  • the surface of the sheet-shaped contactor and the surfaces of said areas on the selector contactors are parallel to each other.
  • the switching state is changed by an actuator acting on the opposite free end of the sheet-shaped contactor.
  • the actuator is under the action of a compression spring, whereby it exerts a pulling action on the opposite end of the shift range of the leaf spring. Due to the pulling action of the sheet-shaped contactor receives a stretched shape.
  • the switch according to the EP 1 533 823 A1 is thus a so-called snap-action switch, which has other switching properties than the first-mentioned switch according to the DE 44 20 665 B4 , Above all, with the switch according to the EP 1 533 823 A1 an exact setting of the switching function is not possible, as has been described at the beginning.
  • the invention is therefore an object of the invention to provide an electrical switch in which the switching behavior during the switching regardless of the type of operation can be accurately adjusted, which also allows an intermediate position with contact to both Wahlrobe stresses and yet with a simple structure, easier production and easy assembly allows reliable operation over long periods of time.
  • an elastically deformable contactor is provided in the basic form of a leaf spring.
  • the deformation state of this contactor is changed by the action of an actuator.
  • the contactor is provided with contact fingers which protrude from the plane of the leaf spring and can slide over contact surfaces formed on the first and second selection contact bodies.
  • the sliding sweep of the contact surfaces by the contact fingers on the type of sliding contacts causes a self-cleaning of the contact surfaces. This is important if the switch must be operated under adverse environmental conditions and, for example, oxide layers, silicate layers or other undesirable deposits on the contact surfaces can occur. Disturbing foreign layers can often be eliminated mechanically. Also foreign particles or abrasion particles of plastic parts can be removed by the sliding contacts from the common contact surface of contact fingers and contact surfaces.
  • a separate return spring for the actuator is not required in principle.
  • the formed from the basic shape of a leaf spring elastically deformable contactor is inexpensive to produce as a simple stamping with bends and yet a multi-functional part, the function of a movable switching member, an electrically conductive contact and a return spring united in it.
  • Claim 2 expresses above all the functional distribution of the contactor to which a clamping area, a central deformation region and an adjoining stiffened actuating region is successively provided, from which the contact fingers go out.
  • the contactor can have either a stepped shape, a U-shape or an angular shape.
  • a step shape is meant that the clamping area and the actuating area - similar to a Z-shape - lie in two different planes and are interconnected by the deformation area extending therebetween, approximately perpendicular thereto.
  • U-shape clamping area and operating area are also in different levels, but are facing each other, wherein the legs of the U forms the deformation region.
  • the apex area of the angle replaces the leg in the U-shape.
  • the expressed in claim 2 design is the function of the contactor as a multifunction part conducive.
  • the embodiment according to claim 2 has the further advantage that the extent of the clamping region, the deformation region and the actuating region can be distributed differently over the length of the contactor. Thereby, a different gear ratio between the movement of the actuator and the switching paths of the contact fingers can be selected and set in the design of the switch. This means a further possibility of variation for the switching behavior.
  • the actuator and the contactor with the contact plate connected to a fixed common linear motion. The movement of the actuator and the contact finger is thus fixed to the ratio of 1 to 1.
  • the residual stress or bias of the contactor is sufficient to cause the required return to the preferred switching position.
  • the residual stress or bias of the contactor is sufficient to cause the required return to the preferred switching position.
  • Claim 4 shows the possibilities for stiffening the operating area, while claim 5 has a particularly advantageous way to approach the contact fingers on the operating area to the object.
  • the claims 6 and 7 include an advantageous embodiment of the contactor and the selector contact body, as they come in particular in a contactor with step shape in question.
  • the claims 8 and 9 show advantageous design options based on the design of the contactor in U-shape.
  • the claims 10 and 11 have a modified embodiment of the subject, which proceeds from the formation of the contactor in angled shape.
  • the contact fingers bent from the contactor move with their broad side on the contact surfaces of the two selector contact body. Even if the serving as sliding ends of the contact fingers are executed in the usual manner angled or warped, results in a narrow contact surface, which moves with its broad side over the contact surfaces of the selector contact body.
  • This is a clear difference from the prior art according to the DE 44 20 665 B4 and supports a safe switching behavior as well as the self-cleaning of the switch.
  • the prior art carries the specified in the claims Paired arrangement of the contact fingers due to their redundancy considerably for switching reliability.
