Definitions

  • the invention relates to an electrical slide switch according to the preamble of patent claim 1.
  • Such a slide switch is known from DE-A-1 935225.
  • a contact bridge attached exclusively to the slide by means of spring tongues carries contacts on both sides and thus serves as a contact rocker.
  • This contact bridge has two "contact positions", which can be referred to as “end positions” due to the limitation by counter contacts.
  • swivel levers are arranged on both sides of the slide, which serve as a separating mechanism. If the slide is moved into an end position, stop surfaces on the slide come into contact with projections of the swivel levers, as a result of which they are pivoted in such a way that their noses projecting towards the contact bridge come into contact with the latter and thereby forcibly the switching contacts of the contact bridge from the separate the assigned contacts. It is therefore a switch that is switched on in the de-energized state and is to be opened under electrical load. The opening takes place through the actual active actuation, while the closing takes place in reverse of the above-mentioned process.
  • a similar slide switch is known from DE-A-2 228 096.
  • two contacts of a snap switch are movably mounted, with a rocker-type insulating slider being pivotably mounted on a curved slideway and slidable in itself.
  • a lever arm of the insulating slide ensures a forced separation of the contacts in a switch position.
  • FR-A-2 308 182 also shows an electrical snap switch in which the usual snap spring is connected to the contact rocker.
  • a lever mechanism is provided, one end of which actuates the free end of the snap spring and the other end of which, in the case of welded contacts, acts on the end of the contact rocker which is close to the contacts and thus causes a forced separation.
  • the forced separation is achieved in that an insulating material lever is mounted in a housing closing plate that can be separated from the housing and can be brought into contact with a pin protruding from the slide, so that the nose of the insulating material lever is essentially vertical protrudes into the swivel range of a contact rocker mounted in the housing, which moves the contact rocker from its associated contact.
  • the insulating material lever is resiliently biased in a direction in which it is out of engagement with the shift rocker. This makes it easier to operate the insulating material lever, since it only has to be done in one direction.
  • the spring action of the insulating material lever is achieved in a particularly simple manner in that the insulating material lever has a spring arm which is integrally connected to it and which is supported against a supporting surface of the housing closing plate.
  • a particularly simple mounting of the insulating material lever is obtained by holding it in a recess in the housing closing plate on a pivot bearing designed as a bolt, only the nose protruding from the recess.
  • a pivot bearing designed as a bolt it is expedient to design the end of the bolt as a caulking peg, as a result of which the insulating material lever can be attached to the housing closing plate simply, securely and permanently.
  • each contact rocker is assigned its own insulating material lever.
  • Fig. 1 shows an embodiment of a two-pole slide switch, in which the invention is used.
  • the housing is open here, whereby the separating mechanism cannot be seen.
  • a slide 2 In a housing 1, a slide 2 is guided in a straight line and protrudes with one end out of the housing.
  • Two contact rockers 3, 3 ' (see FIGS. 34 and 35) are arranged within the housing essentially transversely to its longitudinal extent, each of which is pivotably mounted in a support eye 4, 4' (see FIGS. 36 and 37).
  • the support eyelets 4 and 4 ' are laterally attached to the housing 1 in corresponding recesses.
  • the contact rockers 3 and 3 ' are pressed into their swivel limit positions via spiral springs 5 and 5'.
  • the coil springs are supported at one end on a projection 150 (FIG. 34) of the contact rocker and at their other end on a projection 15 or 15 'on the slide.
  • the switch is open, i.e. Contact surfaces 20 and 20 'of the rocker arms 3 and 3' are removed from contact surfaces 21 and 21 'of associated contact eyelets 6 and 6'.
  • These contact eyelets 6 and 6 ' are also fastened in suitable recesses on the housing 1 and are located on the side of the housing opposite the support eyelets 4. If the slide is moved to the left in FIG. 1, the springs 5 are thereby tensioned and at the same time are shifted to the left with their end facing away from the switching rockers. The end of the springs facing the contact rockers initially remains stationary. As soon as the projections 15 and thus the ends of the springs facing away from the contact rockers have been moved beyond a certain point, the springs push the contact rockers in FIG. 1 to the right, so that the contact rockers with their contact surface in the direction of the contact eyelets 6 or 6 ' "Snap". In this case, the contact surfaces 20 and 20 'come into contact with the contact surfaces 21 and 21'.
  • the slide is then held in the switched-on position of the switch via a latching mechanism 10 (FIG. 2).
  • a latching mechanism 10 FIG. 2
  • the slide is first pushed a little further to the left in Fig. 1, whereby the locking mechanism disengages again, whereupon the slide under the action of the spring 7, which is supported on the one hand on the housing 1 and on the other hand on the slide 1 on the right, whereby the switching process takes place in an analogous manner.
  • Lateral fastening arms 18 are provided on the housing, each of which has a screw opening 19.
  • the housing has upward outstanding locking catches 14, which are used to fasten a housing closing plate 8 (FIG. 2).
  • a support 16 projecting from the bottom of the housing, from which a pin 17 protrudes, by means of which the housing closing plate can be centered and fastened.
  • the separating mechanism contains, as an essential element, an “insulating lever” 9, which is pivotably mounted on a bolt 13 of the housing closing plate 8.
  • a nose 12 of the insulating material lever 9 projects into the pivoting range of the switch swing in 3.
  • the pin 11 projecting upward from the slide 2 abuts against a stop surface of the insulating material lever and pivots it, as a result of which the lug 12 comes into contact with the switching rocker 3 and pushes it out of its closed position.
  • Fig. 2 the switch is shown in the open position, in which the rocker arm 3 is located away from the nose 12.
  • the insulating lever 9 is accommodated in a recess 25 of the housing closing plate 8, only the nose 12 protruding beyond the silhouette of the housing closing plate 8.

Furthermore, the pins 11 and 11 'can be seen in their two limit positions, the position of the pins in the switched-on position being characterized in that their reference numerals are placed in brackets. From this it can then be seen that the pins 11 and 11 ', in their one limit position, press against a nose of the insulating material lever and pivot it against the force of the spring arm 22 and 22', the insulating material lever then assuming the position shown in dashed lines and in front all the nose 12 or 12 'is also pivoted.
  • FIG. 4 shows a schematic sectional view, in which - in contrast to FIG. 2 - one insulating lever 9 is shown in full, while the other insulating lever 9 'is partially broken open in order to identify the position of the pin 11' more precisely.
  • Fig. 5 shows a schematic plan view of the switch with the position of the insulating lever 9 or 9 '.
  • the contact rocker 3 is already opened by the spring 5, i.e. removed from the contact eyelet 6 while the contact rocker 3 'is still in contact with the contact eyelet 6'.
  • the nose 12 'of the insulating material lever 9' would have already pushed the contact rocker 3 'away.
  • 5 is essentially used to show the extent to which the nose of the insulating material lever moves the contact rocker.

When the slide is slightly moved back, the leg 182 then abuts the wall 102, where it is guided up to the nose 105. In this position, the slide and thus the switch is in its one stationary position, specifically in the illustrated embodiment with the arrangement of the contacts according to FIG. 1 in its switched-on position. When the switch is actuated again, the leg slides along the nose 105 to the wall 111 and is guided there to the wall 112. The slide is then again in its foremost limit position. When released, the leg is then guided between the walls 113 and 104 or 114 and 103 and then slides along the wall 115 to the transverse wall 117, where the switch is in its other limit position, which in the exemplary embodiment shown is its switched-off position.

Specifically, the legs 181 and 182 point essentially at right angles from the middle leg 180, whereby they are each bent on two different sides and are therefore antiparallel to one another.
