Definitions

  • a similar but separate construction is required, namely with a push button, a plunger and an auxiliary switch plunger, which again interacts with the armature and with the contact bridge as a break contact.
  • This design not only provides two push buttons with plungers and auxiliary switch plungers, both of which interact with the armature, but also two contact bridges, i.e. a total of four contact bridges, which force a total of eight connections for the wiring.
  • the construction effort and also the wiring effort are therefore quite considerable, apart from the fact that the auxiliary switches which are responsible for these functions are used, are practically lost for other switching purposes.
  • DE-C-592 266 discloses an electromagnetic contactor which can be operated by means of a switch-on push button.
  • This contactor has a curved spring clip which is connected at one end to a fixed contact rail and at the other end a movable contact piece is attached.
  • an auxiliary contact controlled by the contactor armature is provided for holding the contactor in the switched-on position.
  • the auxiliary contact is closed by a contact on the switch-on button.
  • the push button has a recess so that the auxiliary contact can be closed regardless of the switch's switch-off position.
  • the invention has for its object to provide a contactor which directly fulfills the functions of switching on, latching and switching off and in which the construction and space requirements are considerably reduced and simple wiring is possible.
  • the housing of the contactor consists of several housing parts 11, 12 and 13, which are made of tough plastic.
  • the housing part 11 is used with its bottom plate 11 a for attachment to an attachment level, for. B. on a control panel or in a control cabinet.
  • the side projections 11e with bores can be used for fastening, or a bolt 11h under pressure from a spring 11k (FIG. 12) can be provided, which engages together with a counter-stop in a profiled rail (not shown) of the control panel or the control cabinet.
  • the magnet system is housed, which consists of a coil 16 with connecting lines 17 and connectors 18, 19 and a magnetic core 34 and a movable armature 31.
  • the coil 16 and the magnetic core can be fastened using a Bracket 14 can only be done by simply inserting it with a clamping effect.
  • the housing part 12 contains a contact system.
  • four switching chambers 12d are provided in parallel next to each other within the predetermined width between the two side surfaces 12a.
  • One of these switching chambers preferably the switching chamber 12f shown in FIG. 11 near the front edge, is designed in accordance with the switching chamber 35 explained above.
  • the interrupters as such are essentially designed as U-shaped grooves with open end faces.
  • the U-shaped channels open towards the side away from the mounting level.
  • In the switching chambers 12d there are two contact rails 24 with fixed contact pieces 24a, which are held by inserting in guides 26, 27 of the housing part 12 and in an essentially rectangular frame 30 by contact connection screws 21.
  • the contact connection screws 21 simultaneously hold the electrical connection lines 28.
  • the housing part 12 In addition to the explained switching chambers 12d and 12f of the housing part 12, there is another channel-like within the predetermined width between the side walls 12a Room 12-e provided in which the two connection screws 22 for the coil of the magnet system are accommodated.
  • the housing part 13 can also be attached to the housing part 12 by sliding and clamping.
