Definitions

  • Switch system in particular for device switches, with at least one movable contact piece which can be moved from a switch-off position into a switch-on position by means of a switch actuator, and with a housing which has at least one receptacle for a counter-contact piece which can be contacted by the movable contact piece in its switch-on position.
  • Such a switch system is known from DE-AS 10 97 002.
  • This document essentially relates to a push button switch with a cuboid housing open on one long side, the bottom of which is opposite the open long side and has its guide or holding means for the slide and its locking in the lower position, wherein when stringing together several housings to form a switch group, the bottom of one housing covers the opening of the other housing and the switch groups penetrate threaded bolts through holes in the guide cams of the housing is held together, with pins on the housings interacting with cutouts in order to fix the position of the housings and the two outer fastening brackets to one another.
  • an electromagnetic relay with a contact set arranged in a closed contact chamber of an insulating housing, a spring-loaded bridge contact carrier anchored with its fastening end at the bottom of the contact chamber extending essentially over the entire height of the chamber and with it at its free end applied bridge contact cooperates with two mating contact elements inserted into slots in the side wall, whereby it can be actuated by a contact slide guided in an opening in a housing partition, the fastening end of the bridge contact carrier being anchored in a foot piece made of insulating material and enclosed on all sides by the latter, which is can be inserted from the outside into a bottom opening of the contact chamber and at the same time encloses this bottom opening.
  • the movable contact piece is designed as a bridge, the two end sections of which, when the switch is closed, contact one of the mating contact pieces, which are fixed captively in a suitable manner in the switch housing.
  • These mating contact pieces are usually provided with a screw connection, plug connection or solder connection.
  • the switch housing In the Mounting the device or the like, in which the switch system is installed, the switch housing must be connected to the device, for example by means of screws.
  • the connection between the connecting lines and the connections of the mating contact pieces must be established.
  • the invention has for its object to provide a switch system, in particular a device switch system, which is cheaper than the known, comparable switch systems, at least in connection with the associated device or the like, that is also taking into account the assembly effort.
  • a switch system with the features of claim 1.
  • switch systems are not or are not completely equipped with the required mating contact pieces, at least the assembly costs for the missing mating contact pieces are eliminated.
  • switch systems whose movable contact piece is designed as a bridge, both fixed contact pieces or only one of the two may be missing.
  • the switch system according to the invention is therefore only functional when the missing fixed contact piece or the missing fixed contact pieces have been inserted into the associated receptacle, which is preferably done by inserting each missing fixed contact piece into its receptacle when the switch system is installed in the device or the like .
  • the receptacle in a preferred embodiment therefore has an insertion opening penetrating the wall of the switch housing. This insertion opening is preferably designed as a guide channel for the contact body, in order to ensure that it comes into the correct position in the switch when plugged in.
  • the part of the receptacle located within the housing has a support surface facing the movable contact piece for the contact body to be inserted, which at least partially forms the counter-contact piece.
  • the switch housing is provided with one part of a plug connection, this plug connection being designed in such a way that its plug-in direction corresponds to the direction in which the mating contact piece has to be inserted into the switch housing. Only a single plug-in process is then required in order to arrange the switch in the device or the like in the correct position and to insert the mating contact piece or the mating contact pieces into the switch. It is particularly advantageous to arrange the part of the plug connection provided on the wall of the housing coaxially with the insertion opening for the mating contact piece.
  • At least one latching connection consisting of a resilient pawl and a catch is provided, which engages at the end of the plugging process.
  • the switch system according to the invention can not only be completed by means of mating contact pieces which are fixedly arranged on the device. If necessary, you can also subsequently insert counter-contact pieces that are provided with a plug connection, a screw connection or the like.
  • the mating contact piece is provided with at least one longitudinal slot which extends as far as the end to be located in the interior of the housing.
  • a wire can be clamped in such a longitudinal slot, which simplifies the connection of this wire, which belongs, for example, to a lighting device, which further reduces the costs.
  • Contacting a wire in such a longitudinal slot is particularly problem-free if the wire lies in a channel crossing the longitudinal slot and is fixed in it in such a way that it is aligned with the longitudinal slot and can be supported on the channel wall.
  • the two parts which make up the switch housing are connected to one another by means of integrally formed pins which engage in corresponding openings when the housing parts are joined and, like these, have a shape which leads to a latching.
  • the device switch or the switch system shown in FIGS. 1 to 4 has an essentially block-shaped switch housing which is composed of an upper housing part 1 and a lower housing part 2.
  • a peg-shaped switch actuator 4 which is molded onto a carrier 5 for two contact bridges 6, which form the two movable contact pieces of the two-pole switch which are located parallel to one another.
  • Carrier 5 and on the other hand is supported on the bottom 8 of the lower housing part 2.
  • the carrier 5 has two diametrically arranged supports 10, which project transversely to its direction of movement, for the two contact bridges 6, each of which is pressed against its support 10 by a helical compression spring 11.
  • the helical compression springs 11, on the other hand, are supported on two arms 12 which are also formed in one piece with the support 5 and which, at a distance above the supports 10, protrude transversely to the direction of movement of the support 5 from its central part, which, as shown in FIG. 4, has two guide ribs 13 is provided, which extend in the direction of movement of the carrier 5 and are each guided by a groove-like guide 14 of the lower housing part 2.
  • At least one of the two arms 12 carries in the region of its free end a leg spring 15, the legs of which extend from the arm 12 against the base 8 against a sliding surface of a portion of material 16 of the lower housing part 2 projecting from the base 8.
  • the two sliding surfaces are provided with lugs 17 projecting against one another, which are engaged behind by the two ends of the leg spring 15 when the carrier 5 is in the closed position of the switch. This non-positive latching produces a snap effect and reduces the force that must be exerted on the switch actuator 4 after the switch is closed in order to keep it in the closed position.
  • a fixed contact piece 19 with a screw connection is assigned to one end of the two contact bridges 6, which are slit conically in the longitudinal direction in their two end sections and therefore have two contact pills 18 on the underside in each end section.
  • These two fixed contact pieces 19 are held by the upper housing part 1 in their receptacle provided in the lower housing part 2. They each have a longitudinal bore 20 extending transversely to the direction of movement of the carrier 5 for receiving the conductor to be connected and a transverse bore 21 accessible from outside the housing and containing a clamping screw (not shown).
  • these two fixed contact pieces 19 could also be provided with a plug connection or a solder connection.
  • the switch housing On the side opposite the two fixed contact pieces 19, the switch housing has two insertion openings 22 with a rectangular cross section, the longitudinal axes of which are parallel to one another and to the axes of the longitudinal bores 20.
  • the insertion openings 22 are delimited in their lower part by the lower housing part 2 and in their upper part by the upper housing part 1, as a result of which they can be produced without problems.
  • truncated cone-shaped projections 23 are formed concentrically with both insertion openings 22 on the outside of the housing wall having these insertion openings 22, each of which forms part of a plug connection and also extends the channel formed by the insertion openings 22.
  • the cross section of the insertion openings 22 is adapted to the cross section of tab-shaped contact pieces 24 which are inserted into the interior of the housing through the insertion openings 22 only when the switch is installed in the associated device.
  • the lower housing part 2 forms a support surface 25 for the material section 16 Contact piece 24.
  • FIG. 1 shows that the insertion opening 22 and the support surface 25 are arranged such that the contact surface facing the contact bridge 6 lies in the same plane as the contact surface of the fixed contact piece 19 fixed in the switch housing.
  • the two contact pieces 24 are formed by the end sections of a flat plug, which protrude beyond the area 26 of the associated device intended for the contact of the switch housing.
  • a truncated cone-shaped depression 27 is provided in the surface 26 concentrically with the two tabs, the shape of which corresponds to that of the projections 23.
  • the two plug-in contact pieces 24 are provided with a central, conical longitudinal slot 30 which extends to the free end of the contact piece 24.
  • the two tongues lying next to one another are contacted by one of the two contact pills 18 of the associated end section of the contact bridge 6. Since, as shown in FIG. 1, the end sections of the contact bridge 6 adjoining a central section are bent toward the contact surfaces of the contact pieces 24, the contact pills 18 are displaced on the contact pieces 24 when the contact bridge 6 is pushed through into its extended position. This creates a self-cleaning effect on the contact surfaces.
  • Each of the two longitudinal slots 30 is crossed at right angles by a channel 31 provided in the lower housing part 2 and continuing into the upper housing part 1, in which a connecting wire 32 of a component 33 to be electrically conductively connected to the contact piece 24 is located, in which it is in the exemplary embodiment is a capacitor.
  • the diameter of the connecting wire 32 is somewhat larger than the width of the longitudinal slot 30. Good contact is therefore achieved when the contact piece 24 is inserted through the insertion opening 22 and the connecting wire 32 enters the conical longitudinal slot 30 and expands it somewhat.
  • the lower housing part 2 For receiving the component 33, the lower housing part 2 is provided with a chamber 34 which is open at the bottom and on the side walls of which hooks 35 are formed, which, as shown in FIG. 2, hold the component 33 in the chamber 34. Therefore, the assembly of the component 33 is extremely simple and inexpensive.
