to disconnect the circuit when faults occurs
AnswerA 'disconnector switch' is another term for an 'isolating switch' or 'isolator'. It is a manually-operated switch used to provide a visible break between a de-energised part of a circuit and the energised part of a circuit so that work can be carried out safely on the de-energised part. A disconnector switch is not intended to break a load current, and most certainly not designed to break a fault current -that is the function of a circuit breaker.

What is lighting impulse test on disconnector?
Lightning Impulse withstand test is a destructive test carried out on high voltage switchgear. It is classed as a destructive test as each shot damages the insulation and lays carbon tracks. The Energy Networks Association Technical Specification (ENA-TS) 41-36 states the BIL (basic Impulse level) Required for the Voltage rating of the piece of switchgear rated up to 36kV. For example an 11kV switchgear will have a BIL of 95kV. Switchgear which include a Vacuum circuit breaker must have a second means of isolation, ie a disconnector. This disconnector can be a two position (mains on, off) or three position (mains on, off, or earth on) disconnector operated off load which is in series with the Circuit breaker. To pass the test 15 shots at +95kV and 15 shots at -95kV are fired at all positions of the disconnector and only 2 out of the 15 (and not the last 5) shots can flash over to earth. For example if the disconnector was in the off position one side will be connected to the impulse generator and the other side will be earthed. Positive and Negative shots will be fired and the impulse can not flash through the air gap to the earthed side of the disconnector. This proves the isolation gap inside the disconnector has a BIL rating of 95kV. Therefore if the incoming side of a switchboard is live and the outgoing side is isolated for maintenance. There can be a transient impulse on the live side of the circuit and it will not flash across the isolating gap and endanger anyone working on the dead side of the circuit
What is the line diagram symbol for a mercury tilt switch?
The diagram symbol for any tilt switch is the ball tilt switch symbol.Then in the table of contents the switch is described,whether it be a ball switch,mercury switch,etc...
Which switch opens the circuit on a tv?
The power on switch
What is regular grammar of a switch in C programming language?
Perhaps you meant 'switch statement' instead of 'a switch'?Something like this: -> -> switch () -> { } -> (empty) | -> []; -> | -> case: | default: -> | break;
What happens if the switch is open?
If the switch is open, current does not flow.
What is electricity isolators?
An electricity isolator, or a disconnector, is used to ensure that an electrical circuit is void of electricity during maintenance.

What does a disconnector do when a 1991 type pistol is fired?
It disconnects the trigger from the sear. Visualize the pistol firing- you pull the trigger, sear moves, allowing hammer to fall, gun fires, slide recoils, ejects empty, slides forward, chambering fresh round- but you still have the trigger pulled. Without the disconnector, the hammer would have followed the slide forward, either being out of cocked position for the next shot, or causing full auto fire. However, the disconnector acts faster than your reflexes, and unhooks the trigger from the sear, until you release the trigger, and pull it again.
What is the name of the safety feature that is designed to ensure that when the trigger is held rearward after a round is fired the semiautomatic it will catch the hammer hook?

Sear and disconnector reassembly in colt series 70 gold cup?
The manual only shows the parts and advises one to take it to an authorized repair service or I guess a gunsmith would know how to reassembly the parts.
What is isolator with earth switch?
A disconnector or isolator switch is used to make sure that an electrical circuit can be completely de-energised for service or maintenance. Such switches are often found in electrical distribution and industrial applications where machinery must have its source of driving power removed for adjustment or repair. High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers and transformers, and transmission lines, for maintenance. Often the isolation switch is not intended for normal control of the circuit and is used only for isolation; in such a case, it functions as a second, usually physically distant master switch (wired in series with the primary one) that can independently disable the circuit even if the master switch used in everyday operation is turned on.Isolator switches have provisions for a padlock so that inadvertent operation is not possible (see: Lockout-Tagout). In high voltage or complex systems, these padlocks may be part of a trapped-key interlock system to ensure proper sequence of operation. In some designs the isolator switch has the additional ability to earth the isolated circuit thereby providing additional safety. Such an arrangement would apply to circuits which inter-connect power distribution systems where both end of the circuit need to be isolated.The major difference between an isolator and a circuit breaker is that an isolator is an off-load device intended to be opened only after current has been interrupted by some other control device. Safety regulations of the utility must prevent any attempt to open the disconnector while it supplies a circuit.Standards in some countries for safety may require either local motor isolators or lockable overloads (which can be padlocked).
