  • Installation switching devices in this context are in particular circuit breaker or spring current circuit breaker having at least a single or double contact point and the housing has approximately a T-shape.
  • auxiliary switches are used, which normally have the same outer contour as the service switching device itself and the side are attached to one of the broad side surfaces.
  • the switching position of the movable contact piece or optionally the contact bridge is transmitted to the auxiliary switch, whereby the switching position is displayed.
  • auxiliary switch is attached to the rear narrow side surface.
  • the auxiliary switch is a microswitch and the housing has a projection which can be inserted into a terminal opening.
  • a provided with an inclined slide valve is the plunger of the microswitch with the movable contact piece or the movable contact lever in conjunction.
  • terminals that are actuated from the front for connecting signal lines.
  • the object of the invention is to provide a service switching device with an auxiliary switch of the type mentioned, in which the assembly is simplified and beyond an excessive manual force when tightening the clamping screws of the auxiliary switch has no Auswirdungen on the auxiliary switch.
  • the service switching device has on the rear narrow side subsequent broadsides each one parallel to the narrow side groove or strip and the auxiliary switch housing parallel to the broad sides towards the narrow side projecting wall sections are formed, which are adapted to the grooves or strips, so that the auxiliary switch housing perpendicular to Fixing level on the narrow side can be mounted by inserting from the front to the mounting plane towards the service switching device, wherein the integrally formed on the Wandungsabroughen projections or strips in the grooves or strips on the broad sides.
  • the auxiliary switch does not exceed a certain end position when inserting the opposite ends of the mounting plane of the service switching device ends of the wall sections are connected to each other by means of a transverse wall.
  • locking means are formed on the narrow side surface and on the narrow side surface adjacent wall of the auxiliary switch housing, which serve to lock the auxiliary switch housing in its end position.
  • a nose can be integrally formed on the auxiliary switch housing, which engages in a recess on the service switching device.
  • the auxiliary switch housing is constructed in two parts, with a lower housing part and an upper housing part, which acts as a kind of cover.
  • the lower housing part has the wall sections, the transverse wall and the nose, whereas the upper housing part has the access openings to the clamping screws.
  • An installation switching device 40 for example, a circuit breaker is constructed in Sockeweise with a T-shape, wherein the free end surface of the transverse web 41 forms the mounting plane 42.
  • the free end of the longitudinal web 43 is referred to as the front front side 44, to which connect front narrow side walls 45, which pass into the rear front surfaces 46; in the drawing, only the left front narrow side wall and the left rear front wall 46 is drawn; These rear front walls 46 are followed by rear narrow side walls 47, wherein an auxiliary switch 48 is connected to the rear narrow side wall 47 on the left in the drawing.
  • the service switching device 40 has a contact point 28 with a movable contact lever 29, to which a transmission element 21 is attached.
  • a slider 16 cooperates, as shown in more detail below, wherein the slider 16 faces with its one end 20 of the contact lever 29 and touches it.
  • the auxiliary switch 48 has a housing lower part 1 and a housing upper part 2.
  • a microswitch 3 and 4 terminals are added, which are connected via lines 5 to the terminals of the microswitch 3; one of the terminals is connected to one terminal of the microswitch 3 and the other terminal is connected to the other terminal of the microswitch 3.
  • the terminals 4 have clamping screws 4 a, through two openings 7, see Fig. 5 and 6 , Are accessible, so that the terminals 4 are actuated by means of a tool.
  • a slider 9 with a so-called ramp 10, which cooperates with the plunger 8 of the microswitch 3.
  • the microswitch 3 and the sliding element 9 which has an L-shape, of which one leg 9a has the ramp 10 and the other perpendicular leg 9 b forms a stop for a compression spring 11, the other end against the microswitch 3 is applied, there is the compression spring 11; It thus sits between the microswitch 3 and a side surface of the microswitch 3 and the leg 9 b.
  • the plunger 16 has an L-shape, see Fig. 2 with an elongated leg 16 a and a web 19; this web 19 abuts against the other leg 9 b of the slider 9.
  • the Fig. 3 shows a perspective view of the service switching device 40 and there on the rear narrow side wall 47. It can be seen that the service switching device has a housing with two shell halves 24 and 25; the one, in the drawing Fig. 3 Rear drawn switching half 24 has on the rear narrow side surface 14 has a slot 17 through which the longer arm 16 a of the slider 16 can be inserted therethrough.
  • the assembled state represents the Fig. 4 represents.
  • the lower housing part 1 has a rear rear wall 50, which is adapted to the rear narrow side wall 47 and in the mounted state also bears against this narrow side wall 47.
  • a rear rear wall 50 At the parallel to the broad sides 14 of the service switching device 40 extending side walls 51 and adjoining the rear wall 50 Ekken, these are the transition corners of the side walls 51 to the rear wall 50, are L-shaped, projecting in the direction of the narrow side wall 47 Wall sections 12, the free leg ends 53 and 54 assign each other.
  • the fastening plane of the switching device 40 opposite end of the wall sections 53 and 54 are connected by a transverse wall 13.
  • a detent 22 is connected, which cooperates with a recess 23 on the service switching device as a latching means.
  • the slide 16 is first pushed through the slot 17 into the interior of the switching device 40, then the auxiliary switch housing lower part 1 and upper part 2 is mounted on the circuit breaker 40, in which the facing each other legs 53 and 54 are inserted into the grooves 15, wherein the insertion direction extends from above perpendicular to the front surface or parallel to the rear side surface.
  • the rear wall 50 has one of the rounding 47 a corresponding hollow-shaped rounded portion 50 a, which limits the insertion of the auxiliary switch 1 together with the transverse wall 13.
  • the side walls or side walls 51 of the auxiliary switch have parallel thereto, downwards, ie in the mounting direction projecting walls which lie on both sides to an opening 26 through which a connecting conductor in a terminal in the switching device 40 can be performed.
  • the service switching device 40 has a receiving space 60 for a terminal; a lead is pushed between the extensions 26 and through the opening 26 to the terminal and clamped there.
  • the auxiliary switch housing has, as indicated above, a lower housing part and a lid, wherein the lid has a U-shape; one leg 61, which faces the front narrow side wall of the service switching device and projects perpendicular to the mounting plane in the direction of the mounting plane, engages in a recess 62 on the side walls 51 of the housing base; the other leg 63 projects into an undercut 64 on the lower housing part.
