Definitions

  • the invention is based on a switch with a box-shaped housing body that can be installed in a switch cabinet, on the front of which a switch lever and an additional device are arranged, which can be guided to the outside through a door of the switch cabinet.
  • a switch is installed in a control cabinet, at least two openings are usually provided in a wall of the control cabinet, preferably in the form of a door, one of which carries out the switching lever required to actuate the switch contacts and another of which carries out the additional device, such as a display device , serves.
  • the switch can then be operated and monitored without the need to open the cabinet door.
  • Additional devices are generally dimensioned differently and also often have differently designed fastening devices. This often complicates their assembly in the switch and the openings in the control cabinet door also differ in terms of their shape and dimensions.
  • the invention is based on the object of specifying a switch of the type mentioned, which can be equipped with any additional device in a simple and rapid manner, without the switch cabinet receiving the switch carrying out the additional device serving specially dimensioned opening required.
  • the switch according to the invention is characterized in that a defined contact surface is defined on its front side, which is advantageously delimited by the sides of a rectangle.
  • a defined contact surface is defined on its front side, which is advantageously delimited by the sides of a rectangle.
  • fastening means are provided with at least one insertion opening led into the housing body of the switch from the edge of the support surface of the switch and with an insertion protruding outwards into and from the edge of the support surface of each of the additional devices Insertion opening to form a hinge insertable fastening lug.
  • FIG. 1 shows an embodiment of a switch 1 according to the invention, which is mounted inside a switch cabinet, the front of which is closed by a door 2.
  • the control cabinet door 2 has an opening 3 through which an additional device 4 designed as a cover protrudes together with a vertically pivotable switching lever 5 for actuating a contact device of the switch 1.
  • FIG. 2 shows the schematically illustrated housing body of the switch 1 after the cover 4 has been removed.
  • the switching lever 5 protruding from the front of the switch 1 is guided through a support surface 6 of the switch 1.
  • the support surface 6 is delimited by the sides a and b of a rectangle.
  • threaded bores 7 and 8 or 9 and 10 are provided on two parallel sides which limit the contact surface 6 of the switch.
  • slot-shaped openings 11 and 12 are provided, which allow the insertion of fastening lugs 13 and 14 of the additional device 4 designed as a cover and thus a positive connection of the additional device and enable switch 1.
  • the fastening lugs 13 and 14 protrude clearly on one side of the cover 4.
  • the cover 4 can be pivoted in the manner of a hinge onto the contact surface 6 of the switch.
  • the threaded holes 7 and 8 provided in the support surface 6 are aligned with through holes 15 and 16 of the cover 4.
  • two screws 17 and 18 which can be guided through the through holes 15 and 16 and can be fixed in the threaded holes 7 and 8, the cover 4 can now be attached.
  • FIG. 2 also shows an additional device 19 with a space 38 which is dimensioned large enough to be able to receive and actuate the shift lever 5 which can be pivoted from bottom to top and vice versa.
  • the shift lever 5 can be blocked with the help of a lever that can be inserted through openings (not shown) in the side walls of the additional device 19 transversely to the pivoting range of the shift lever 5 and locked in the blocking position with the aid of lockable padlocks.
  • This additional device 19 with its special structure can also be fastened using fastening lugs 20 and 21 and with the aid of screws which are screwed into the threaded bores 7 and 8 of the housing body of the switch 1.
  • An additional device 22 can also be seen in FIG. 2, which has an actuating member 23 designed as a rotatable lever with a switch button, which makes it possible to act on the switch lever 5 of the switch 1 with the aid of a rotary movement.
  • the housing body of the additional device 22, which is heavily stressed during the actuation of the lever, is fixed by means of four screws 24 inserted into the threaded bores 7, 8, 9 and 10. This ensures a particularly firm support of the additional device 22 on the surface 6 of the switch 1.
  • the reference numeral 25 denotes an additional device which can be fastened on the support surface 6 by means of screws 26.
  • the additional device 25 includes a gear driven by a motor and acting on the shift lever 5.
  • the reference numeral 27 designates an additional device designed as a cover with a horizontally extending thickening 28. This thickening forms a particularly stable passage for the shift lever 5 which is guided through an opening 29 in the cover 27 out of the housing body of the switch.
  • FIG. 3 shows an embodiment of the switch 1, in which an additional device 30 designed as a cover protrudes from the control cabinet door 2.
  • the cover 30 has an opening, not designated, through which the switch lever 5 of the switch is guided.
  • Attached to the cover 30 is an additional device designed as a current measuring device with a digital display device 31 which continuously reproduces the value of the current flowing through a phase conductor of the switching device 1.
  • the display device 31 is preferably able to display at least three digits. As can be seen from FIG. 4, the display device 31 can also represent the measuring unit - evident A for the current as a measured variable.
  • the current measuring device is connected via pluggable wires 32 to an additional device of the switching device 1 designed as a protective unit 33.
  • the protective unit 33 has an auxiliary circuit which is not shown in FIG. 4 and which is supplied with current via a connecting part which is likewise not shown in FIG.
  • a part of the wires 32 is galvanically connected, for example by plugging, to current-carrying wires of the connecting part and serves to supply power to an auxiliary circuit of the current measuring device.
  • Another part of the wires 32 is via a plug connection connected to a data bus of the protection unit 33 shown in FIG.
  • This data bus which is denoted by reference numeral 34 in FIG. 5, carries information relating to the current flowing in the switching device 1. This information can be both in analog form and in digitally coded form.
  • the data bus 34 is connected to a logic circuit 35, which is arranged on the cover 30 and is capable of encoding and processing the information present in the bus 34 in such a way that it is suitable for display on the display device 31.
  • the logic circuit 35 acts on the display device 31 via a driver circuit 36.
  • the current measuring device shown is completely installed in the cover 30 and can be supplied with feed current and measurement signals as described. The current can also be read when the switching device 1 is installed in the control cabinet and the door 2 is closed without additional openings having to be made.
