Definitions

  • the invention relates to a changeover device according to the preamble of claim I.
  • switches that are suitable for various uses. However, it may then be necessary to limit a switch that can be used in many ways to only one of its possible uses, that is to say to set the switch to its respective use.
  • the invention has for its object to provide an economically feasible changeover device which is simple in construction, space-saving and easy to operate.
  • the latch which can be operated from outside the switch housing, enables the changeover to be carried out simply and quickly.
  • the bolt can be rotated about an axis that is vertical to the housing wall also permits simple operation, but at the same time prevents the bolt from being inadvertently changed, particularly when the bolt arrangement is preferably recessed.
  • the locking points provided on the housing wall and the locking points of the spring clip of the bolt can be advantageously carried out using tools. They can be automatically engaged with each other during assembly, so to speak. Their number is limited at most by the dimensioning, so that more than two positions can be locked.
  • Housing wall with opening and latch can be made in one piece from plastic in conventional plastic precision, which is very economical.
  • the bolt preferably has a continuous hub, on the outer side of which the spring clip is molded, while the guide ring parts are molded on the central part of the hub.
  • two spring clips which lie opposite one another in a common plane and are each partially separated from the hub by an arc-shaped window, form a locking ring which has the largest diameter of the bolt.
  • This locking ring is preferably embedded in a ring-like largest opening part of the housing wall opening and lies over an annular locking base.
  • the locking base delimits the largest opening point radially inwards and carries the associated locking points, which are preferably depressions.
  • the locking points of the locking ring which are preferably projections, lie opposite these locking recesses.
  • the bayonet claws preferably project axially and radially outwards from the latching base toward the axis of rotation in the curved windows of the latching ring and radially overlap the guide ring parts of the bolt.
  • the guide ring parts form a guide ring, which has a smaller diameter than the locking ring, and rests on a guide base, which delimits a central opening part of the wall opening axially inwards.
  • limits are also provided on the detent base, the latter being the detent points of the spring clips as end stops when the bolt is turned serve. These end stops can be chamfered on one side and steep on the other side, so that they can be run over when the bolt is screwed into the opening, but their steep flank opposes the bolt being unscrewed.
  • This embodiment is particularly advantageously designed such that an annular groove closed by the end stops is provided on the latching base, which annular groove is extended in places by the latching points, the spring clips then having projecting latching cams.
  • the wall opening preferably has a smallest opening in which the innermost hub part designed as a centering part sits. This not only results in a good centering of the bolt, but also a good closure of the opening.
  • this innermost and smallest diameter opening part should be as round as possible so that it can optimally fulfill its centering and closing function, but in order to make the bayonet claws easier, it may be necessary to provide recesses for the tool therein, which in turn are closed by the guide ring parts can.
  • An adjustment extension e.g. an eccentric pin and the like can be provided, which protrudes into the switch housing and can be brought about by turning the bolt. He can e.g. enable or cancel a trip position, but also perform other functions.
  • the changeover device can also be designed in a simple manner for straight-line movement.
  • the bolt is designed as a slide with a spring clip running parallel to the direction of movement and the housing wall with bayonet claws running parallel to the direction of movement.
  • the adjustment extension 44 formed eccentrically on the centering part 43 performs an eccentric movement in the interior of the switch during all rotary movements of the bolt 4, which movement can be used for the changeover.
