Description

Schalter mit Widerstand oder Drosselspule.
Die Erfindung betrifft die Vereinigung eines Ausschalters mit einem gewöhnlich überbrückten Widerstand oder Drosselspule. Derartige Schalter sollen hauptsächlich in Stromkreisen für Hausnummern- oder Strassentafel- oder Straenbeleuchtungen mit Verdunklungseinrichtungen, entsprechend den Luftschutzvorschriften, verwendet werden.
Die Verwendung von mit Widerständen oder Drosselspulen vereinigten Schaltern, bei welchen der Widerstand oder die Drosselspule für gewöhnlich kurzgeschlossen ist, so dass die im Stromkreise liegende Glühlampe oder Glühlampen mit voller Leuchtkraft in Betrieb genommen werden können, ist bekannt. Bei den bekannten Ausführungen ist ein Schalter für die Ein-und Ausschaltung des Stromkreises vorgesehen, während zur Kurzschliessung des Widerstandes oder der Drosselspule ein besonderer Schalter dient. Bei der bekannten Einrichtung ist eine unrichtige Betätigung der beiden Schalter nicht ausgeschlossen. Diesem Übelstand, der besonders bei Luftschutzeinrichtungen vermieden werden muss, hilft die Erfindung ab.
Diese besteht darin, dass bei einem mit einem Widerstand 4 oder einer Drosselspule zu einem
EMI1.1
kurzgeschlossen ist, so dass die gewöhnlich bei voller Spannung ein-und ausschdtbare Lichtquelle 6 durch Entfernung des Steckers 5 bei verminderter Spannung bzw. Lichtstärhe ein-oder ausgeschaltet werden kann. Bei Eintritt eines Fliegeralarmes ist infolge dieser vom Schalter unabhängigen Aufhebung des Widerstandkurzschlusses behufs Verdunklung jeder Irrtum vermieden. Der jeweils bestehende Betriebszustand kann, wie an sich bekannt, durch Aufschriften oder Glimmlichtlampen erkenntlich gemacht werden.

Switch with resistor or choke coil.
The invention relates to the combination of a circuit breaker with a usually bridged resistor or inductor. Such switches are mainly intended to be used in circuits for house numbers or street signs or street lighting with darkening devices, in accordance with air protection regulations.
The use of switches combined with resistors or choke coils, in which the resistor or choke coil is usually short-circuited, so that the incandescent lamp or incandescent lamps in the circuit can be operated with full luminosity is known. In the known designs, a switch is provided for switching the circuit on and off, while a special switch is used to short-circuit the resistor or the choke coil. In the known device, incorrect actuation of the two switches is not excluded. The invention remedies this drawback, which must be avoided particularly in the case of air raid protection devices.
This consists in the fact that in one with a resistor 4 or a choke coil to one
EMI1.1
is short-circuited, so that the light source 6, which can usually be switched on and off at full voltage, can be switched on or off by removing the plug 5 at a reduced voltage or light intensity. If an air-raid alarm occurs, any error is avoided as a result of the switch-independent cancellation of the resistance short-circuit for the purpose of darkening. As is known per se, the current operating status can be made recognizable by means of inscriptions or glow lamps.
