  • Such a relay is known from EP 0 514 892 A2.
  • a recess provided in the housing, which is in the Edge area into two adjacent housing sides extends and with a test slide with essentially L-shaped cross section closed at rest becomes.
  • the test slide is partially slidable in grooves who stored a housing wall. By pressing the slide valve towards one or the other of the contiguous Sidewalls this is deformed inwards, with a protrusion on its inside on the anchor of the relay acts as a switching movement.
  • the one there Test slide therefore requires a very large housing recess, which are insufficiently covered by the test slide can be; moreover, it only allows a limited number Stroke.
  • the aim of the present invention is to provide a relay of the input to create the type mentioned with a manual actuator, which has a relatively small opening executed a relatively large actuation stroke by hand can be, by simple modification it additionally it is possible to switch positions inside the relay observe.
  • the Actuator is a swivel mist, one on the outside of the housing outer lever arm, one inside the housing located inner lever arm and a two lever arms connecting hinge section, which in the a recess forming a bearing slot is clamped and a pivoting movement of the actuator about the longitudinal axis of the bearing slot allowed.
  • the inventive design of the actuator as a swivel lever in a narrow bearing slot of the Relay housing is stored, it is ensured that only one relatively small housing opening in the form of this bearing slot is necessary, which is largely due to the swivel lever is locked; also a movement of the pivot lever the opening in the bearing slot does not enlarge. Furthermore can with the swivel lever through the selectable length of the inner Lever arms a more or less large stroke as required are generated, which in the prior art by deformation an actuator located in the plane of a housing wall is only possible to a limited extent or with other known relays only possible with a test button placed far out is.
  • the bearing slot is preferably between in the region of the edge the aforementioned first housing wall and one of them in a second, preferably at a right angle Housing wall formed, the at rest outer lever arm approximately parallel to the first housing wall and the inner lever arm approximately parallel to the second housing wall extend; the pivot axis of the pivot lever extends parallel to the edge of the housing during the movable relay part inside approximately parallel to the first housing wall is movable.
  • a part of the first adjacent to the bearing slot and / or the second housing wall is elastically deformable and a snap-in mounting of the hinge section, the has a reduced thickness compared to the two lever arms, allows in the storage slot.
  • the storage slot facing end edge of the (first) housing wall is there preferably rounded off in the form of a cylinder segment.
  • the hinge section too of the swivel lever in adaptation to the mentioned edge has the shape of a hollow cylinder segment.
  • the outside of the hinge section can also be a flattened, with the opposite end edge of the second housing wall a locking surface defining a locking position exhibit.
  • one of the housing walls and / or on the Swivel lever itself a stop to set a first Working position provided at a predetermined angular position be.
  • the stop is preferably designed such that he in a further movement of the pivot lever in a second Work position is overcome, for example canceled. So it is possible as a stop at least one transverse to the direction of movement of the pivot lever to provide protruding pins, the further movement of the pivot lever in the second working position is canceled. But it can also one or two parallel to the swivel axis on the side Swivel lever projecting stop pin are provided, when moving the swivel lever into the second Working position to be sheared off at an edge of the recess.
  • a movable relay part that can be operated by the swivel lever is preferably one with an anchor and with at least one a contact spring coupled inside the relay Slider provided.
  • This slide is preferably in the second working position can be locked with the inner lever arm, whereby a working position of the armature or the contact spring is locked.
  • the movable relay part i.e. preferably the slide, is movable in parallel along the first housing wall, can be provided by a transparent in the housing wall Window observed the switching position of this relay part become.
  • the movable relay part can have additional marking area in a particular Switch position positioned directly on the window is.
  • the relay shown in Figures 1 to 4 has a housing with a base 1 and a cap 2, in which, for example four changeover contact sets 3 and a magnet system 4 are arranged.
  • Each changeover contact set 3 has one Normally open contact 32 and a working contact 34, which with corresponding Fixed contact carriers are anchored in the base 1, also a contact spring 35 with a movable contact 36, which is also fastened in the base via a spring support 37 is.
  • the magnet system 4 of the relay consists essentially from a coil 41 with a coil body 42, one in substantially L-shaped core 43 and a substantially L-shaped Anchor 44.
  • the core 43 is with its long leg 43a through the coil, so that at its free end Anchor 44 with its short leg 44b is mounted such that it can be rolled off is.
  • the long leg 44a of the armature 44 in turn forms a working air gap with the short leg 43b of the core or with a pole portion 43c, which as an extension of short core leg 43b formed and parallel to the coil axis is turned.
  • the anchor is short with its Leg 44b guided in a pocket of the bobbin 42. He is held in its bearing by an anchor spring 45.
  • the armature movement is by a slide 5 on the contact springs 35 transmitted, each with a bent Operating tab 35a in an associated opening 52nd of the slider.
  • the slide 5 itself is with a mouth-shaped recess 51 on the free end of the anchor leg 44a plugged on so that it is connected to it in an articulated manner is and approximately parallel to in its longitudinal direction an upper housing wall 23 of the housing cap 2 is movable.
  • a pivot lever 6 is arranged in the cap 2 in a recess in the form of a bearing slot 21, which is in the area of the edge between the upper Housing wall 23 and a vertical side wall 24 is located a pivot lever 6 is arranged.
  • This pivot lever 6 forms an outer lever arm 62 and an inner lever arm 63, which are approximately perpendicular to each other and via an im Cross section changed hinge section 64 are connected.
  • this hinge section 64 the pivot lever 6 is around one parallel to the longitudinal direction of the bearing slot 21 Swivel axis movable by a segmented cylinder rounded end edge 25 of the upper housing wall 23 in the area of the bearing slot 21 is formed.
  • this cylindrical end edge 25 is also the inside of the bearing section 64 is formed as a hollow cylinder segment.
  • the housing cap 2 is made of flexible plastic and preferably in the region of the bearing slot 21 in Cross-section weakened. For example, next to the trailing edge 25 shows a cross-sectional weakening or notch 26. In this way, the inner lever arm 63 can be deformed the housing cap 2 snapped into the bearing slot become. After snapping in, the housing cap encloses the Bearing section 64 is tight and holds the pivot lever captively.
  • the outer pivot lever 62 is from the trough 27 pivoted out (with the force F) so that it holds the position 1 or 3.
  • the so achieved the first working position is defined by two stop pins 65, the laterally parallel to the swivel axis of the Stand pivot lever 6 and in this working position on one Bump edge 28. These stop pins are at rest 65 each in a lateral bulge 29 of the trough 27. If you want the relay system to be actuated lock, so the pivot lever according to Figure 4 in a second working position swiveled. For this purpose the Resistance of the stop pin 65 can be overcome.
  • the switching position of the relay is also in a cross section diminished, transparent window 22 of the cap 2 displayed.
  • the slide 5 has an end section with a display surface 53 in the working position the slider directly on the inside of the window 22 lies and is thus visible from the outside.
  • this can Display area 53 additionally striking, for example colored, be designed.
  • FIGs 5 to 7 are slight modifications of the pivot lever and its storage in the housing shown. So is in figure 5 shows a section of the housing cap 2 with the bearing slot 21 shown, the cap not only in the upper end wall 23 has the trough 27, but also in the side wall 24 a wall section 24a weakened in cross section.
  • swivel lever 6 has one outer lever arm 62 and an inner lever arm 63 and one approximately hollow cylindrical bearing section 64. In the central area this bearing section 64 are flattened locking surfaces here 66 provided after inserting the pivot lever 6 in the storage slot 21 different working positions together with the wall section 24a or the projection 24b can set.
  • a lock in the first working position takes place in this example by a stop pin 24c, on which the first lever arm 62 strikes. With further Swiveling the pivot lever 6 into the second working position the stop pin 24c is broken off. The protrusion 24b engages in a recess 67 of the pivot lever.
  • Another modification compared to FIG. 1 is two Window 22 provided laterally from the trough 27. See full ad are then corresponding to the slide in a manner not shown Display areas provided.
  • Figure 7 shows a similar design as in Figure 6.
  • Another modification here is only a stop pin 68 provided on the swivel lever in the first working position strikes at the upper edge of the wall section 24a and the with another pivoting into the second working position is canceled.
