Switch

An interruptory (derivative of rupture) is a device or Organe, Physique or Virtuel, making it possible to stop or authorize the passage of a Flux. One should not confuse the switch which makes it possible to extinguish or light an apparatus, and the switch which make it possible to choose between several active states of an apparatus.

By extension, any system intended to stop something can be called interruptory .

Electricity

In electricity , an interruptory is a Organe or equipment of order which makes it possible to open and to complete supplying an electrical appliance with the values of the nominal intensities. It doubles sometimes Variateur making it possible to modulate the current.


Reverser

It has three electric terminals:
  • a common entered
  • Left n°1
  • Left n°2
It is a switch with an additional state:
  • Closed , it establishes a circuit
  • Ouvert
  • Fermé , it establishes another circuit
Often the stable position, the two open circuits, does not exist. It can be used instead of a switch, it is enough not to cable the second circuit.

Pushbutton

It has two electric terminals:
  • Entered
  • Left
It is a switch with only one stable condition:
  • Open
  • Closed
Only one of the two states is stable, either the state closed (push rod with opening), or the open state (push rod with closing).

Differential switch

It is smaller than a differential circuit breaker, with equal nominal intensity, but its breaking capacity is limited to the nominal intensity, whereas a Disjoncteur (whatever the standard) must be able to cut the running of Court-circuit, that is to say current much the more important. It is thus used only to isolate the circuit when the running is different between two wire from the circuit, case of a defect of insulation (escape of current towards the ground).

To ensure the protection of the people in mode TT a Threshold of release of 30  my is recommended.

Various mechanisms of switch and switch

Lever

The human interface of an interruptory can be a lever. The control stick exceeds on the front face of a support which can be a Instrument panel, on which is very often fixed the switch by a system of nut.




Pushbutton

The switches with pushbutton are actuated by a very simple gesture, quality which justifies their choice when the switch must be handled very quickly, or under conditions requiring a minimum of attention for handling: automobile control , emergency Stop, Keyboard of computer, etc On the other hand their position (actuated or not), is not easily identifiable by the operator, one often associates a indicator to them, integrated or off-set, indicating the state of the circuit.




Slide

A slide switch has the advantage of being able to offer more than three stable positions, with in premium a visual reference mark of its position. On the other hand, it is sometimes badly easy to handle, it generally requires a good attention and a certain tact to be actuated. Moreover, they often show a rather low reliability in the Temps. This type of switch was usually used in the apparatuses of Sonorisation Domestique S, where it from now on is replaced by static electronic switches in Integrated circuit, much more reliable and definitely less expensive.



Rotary

The rotary switches, very often called Commutateur S rotary are ordered by an axis on which is fixed a Bouton which is used at the same time as hub cap. This type of switch can comprise even more stable positions than an interruptory with slide and, can offer many separate circuits. On certain models these two Paramètre S can even be modified before the installation.


Rocking-lever

The switch with rocking-lever are most current. They have an operation similar to the lever, the button rocking-lever being only one lever flat. They are limited in three states, very often only two are used (walk/stop), moreover their position is not always easy to visualize quickly, however certain models, such as for example out of equipment of car, are particularly studied ergonomics question. This type of switch is generally most reliable, because the mechanics of the rocking-lever is particularly adapted to electric commutation: by associating the work of the operator with the action of a very simple system of spring, it ensures of the frank and reliable transitions electric and mechanical.

Magnetic

A Interrupteur Blade Flexible ( THEY or interruptory reed ) is a switch which establishes or cuts an electric connection according to the presence or not of a Magnetic field. It is very often used as a sensor end of the road for the Vérin S, or out of generator of impulses of counting: a permanent magnet fixed on the moving part modifies the state of the switch while passing in front of, thus transmitting information to the control device or the meter.

Mercury

A Interrupteur with mercury establishes or cuts connection according to its slope. The revolved makes it possible to move mercury in the liquid state inside a bulb of Verre provided with two electrode S. This type of switch is used less today because of the Toxicité of the mercury.


Sensitive

A sensitive interruptory also called interruptory tactile , detects the variation of capacity caused by the approach of the finger of the user.


Pressure

An interruptory of pressure uses a pressure pick-up to detect the pressure exerted by the finger of the user.


Electronics

Various technologies allow the manufacture of electronic switches.
