Description

Die Erfindung betrifft einen Drehanlaßschalter, welcher in an sich bekannter Weise mit einer Rückzugfeder versehen ist, mittels welcher bei Loslassen des Schaltgriffes das Schaltorgan .in seine Ruhestellung zurückgedreht wird. Erfindungsgemäß sind dein drehbaren Schaltorgan mindestens zwei Rast-Stellungen- zugeordnet, und zwar eine für die Anlaßstufe und eine für die Betriebsstufe, derart, daß die d er Anlaßstufe entsprechernde Raststellung beim Loslassen des Handgriffes durch die Rückzugfeder überwunden wird, während das drehbare Schaltteil in der Betriebsstellung festgehalten wird. Es wird auf diese Weise einmal verhindert, d@aß die Anlaßstellung unerwünscht lange beibehalten wird, wodurch eine unzulässig lange Überstromaufnahme verursacht werden würde. Andererseits kann man mit der zweiten Raststellung eine Spannungsrückgangsspule oder über eine Verklinkung eine Nullspannungsspule verbinden, so daß bei bestimmten unerwünschten Betriebsverhältnissen die Anlage selbsttätig ausgeschaltet wird.The invention relates to a rotary starter switch, which in itself is provided in a known manner with a return spring, by means of which when released of the switching handle, the switching element is rotated back into its rest position. According to the invention are assigned to your rotatable switching element at least two locking positions, and although one for the starting stage and one for the operating stage, in such a way that the d he Starting stage corresponding locking position when releasing the handle by the Return spring is overcome while the rotatable switching part is in the operating position is being held. In this way it is prevented once that the starting position was used is retained for an undesirably long time, resulting in an inadmissibly long overcurrent consumption would be caused. On the other hand, you can use the second locking position Connect a voltage drop coil or a zero voltage coil via a latch, so that in certain undesirable operating conditions, the system automatically is turned off.

Das Wesen der Erfindung sei im folgenden an Hand eines Ausführungsbeispieles in der Zeichnung erläutert.The essence of the invention is given below on the basis of an exemplary embodiment explained in the drawing.

Die drehbare Schaltscheibe i ist mit ein=er Rückzugfederung 2, die an dem Festpunkt 3 befestigt ist, versehen, so daß der Schalter bestrebt ist, nach Rechtsdrehung um den Drehmittelpunkt ¢ entgegen dem Uhrzeigersinn in :seine Ruhelage wieder zurückzuschnellen. Erfindungsgemäß sind zwei Rasten vorgesehen, und zwar möge die Rast 5 der Anlaßstufe entsprechen, in welcher lediglich ein leicht federnder Finger 6 einrastet, der durch die Rückzugf eder ohne weiteres wieder ausgeworfen wird. Die Rast 7 entspricht dann der Betriebsstellung, in welcher sie durch das Sperrorgan 8 am Hebel 9 durch die Kraft der Zugfeder io festgehalten wird. Durch Linksdrehung der Schaltscheibe mit der Hand kann die Federkraft von io überwunden werden, so daß eine Ausschaltung von Hand jederzeit möglich ist.The rotatable switching disk i is with a = he retraction suspension 2, the is attached to the fixed point 3, provided, so that the switch seeks to Clockwise rotation around the center of rotation ¢ counterclockwise in: its rest position to snap back again. According to the invention, two notches are provided, namely may the latch 5 correspond to the tempering stage, in which only a slightly resilient Finger 6 engages, which is easily ejected again by the retraction spring will. The detent 7 then corresponds to the operating position in which it is through the Locking member 8 is held on lever 9 by the force of the tension spring io. By Turning the switching disc counterclockwise by hand can overcome the spring force of io so that it can be switched off manually at any time.

Der Hebel 9 kann nun andererseits unter der Wirkung einer Spannungsrückgangsspule i i stehen. Wird der am unteren Hebelteil j befestigte Kernteil von der Spule nicht mehr angezogen gehalten, so reicht die Kraft der entsprechend schwach bemessenen Feder io nicht mehr aus, das Sperrglied 8 gegen die Wirkung der Feder 2 in die Rast 7 gedrückt zu halten, und die Schaltscheibe i schnappt in ihre Ruhestellung zurück.The lever 9 can now, on the other hand, under the action of a voltage drop coil i i stand. Does not become the core part attached to the lower lever part j of the spool kept more tightened, the strength of the correspondingly weak ones is sufficient Spring OK is no longer off, the locking member 8 against the action of the spring 2 in the detent Hold down 7, and the switching disk i snaps back into its rest position.
