Definitions

  • the invention relates to an electrical slide switch having at least one contact rocker which can be pivoted by means of a slide and a spring mechanism and which is in contact with a contact at least in its pivoting end position.
  • Such switches with snap mechanism are generally known and are preferably used for switching on and off such electrical devices in which high current peaks occur when switching on, e.g. with color television sets.
  • the spring mechanism ensures that the contact rocker moves quickly as soon as the slide has passed a "dead center".
  • the object of the invention is to improve the electrical slide switch of the type mentioned in such a way that the normal switching function is maintained even with welded contacts.
  • This object is achieved according to the invention by a separating mechanism which forcibly (mechanically) separates the contact rocker from its associated contact when the switch is opened.
  • a weld between the contact rocker and its associated contact is therefore torn open, so that the spring mechanism is then able to move the switching rocker into the open position of the switch.
  • a certain amount of damage to the surface of the contacts touching one another can be tolerated without the function of the switch being noticeably influenced in subsequent switching operations.
  • the separating mechanism is designed as a pivotable insulating material lever which can be pivoted via the slide, the contact rocker being pivoted so that it moves in the direction of a separation of the contact rocker and its associated contact when the slide moves in the direction of opening the switch works.
  • the arrangement of the isolating lever and the contact rocker is preferably selected such that the isolating lever only acts on the contact rocker shortly before the slide reaches the end position.
  • 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 insulating lever is mounted on a housing closing plate, a nose projecting into the pivoting area of the contact rocker can be brought into contact with the contact rocker and a pin protruding from the slide pushes against a stop surface of the insulating lever when the slide moves and panned this.
  • the distance between the stop surface and the nose of the slide thus ensures very simply that the insulating lever only acts on the contact rocker shortly before the slide reaches the end position.
  • the spring action of the insulating material lever is achieved in a particularly simple manner in that the insulating material lever has an integrally connected spring arm 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 of 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 pin, as a result of which the insulating material lever can be easily, securely and permanently attached to the housing closing plate.
  • 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 essentially transversely to its longitudinal extent within the housing, each of which is pivotably mounted in a support eyelet 4,4 1 (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 here with one end on a projection 150 (FIG. 34) of the contact rocker and with its other end on a projection 15 or. 15 'supported on the slide.
  • the switch is open, ie contact surfaces 20 and 20 'of the rocker arms 3 and 3' are removed from contact surfaces 21 and 21 'of associated contact eyes 6 and 6'.
  • These contact eyelets 6 and 6 ' are also fastened in suitable recesses on the housing 1 and lie 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 moved 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 and 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 outstanding locking catches 14, which are used to fasten a housing locking 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.
  • FIG. 2 In the sectional view of FIG. 2 additional details of the housing closing plate 8 as well as the separating mechanism and the snap mechanism can be seen.
  • the separating mechanism contains, as an essential element, an "insulating material 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 switching rocker 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 or 11 'in their one limit position press against a nose of the insulating lever and pivot it against the force of the spring arm 22 or 22', the insulating lever then assuming the position shown in broken lines and in front all the nose 12 or 12 'is also pivoted.
