In switch language, open means to disconnect, or break the circuit. Some people call this "turned off". Closed, is to connect, or make the circuit. Some people call this turned on.
In the case of a normally open switch, the switch is open (off) unless something takes action on the switch. Pushes a button for example, or holds a magnet near the switch, or other active force. A normally closed switch is closed (on) unless some force causes the switch to be opened.
What else can I help you with?
When the switch is closed it means that?
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
Difference between level switch low low and level switch low?
the Low Low is for a Very Low level Alarm, or an emergency status. the Low is just a low level switch who activate any normal output
What is the difference between Layer 2 switch and modem?
The answer choices are not provided for this question. Also this question was miscategorized it should be a networking question not science.
What is the difference between a safety switch and a transfer switch?
Transfer switch means it can transfer the energy from one point to another point. safety switch has automatically control ex: in boilers there are some safety control devices if the preesure/temp exceeds the limit it will automatocally opens. sets the condition. safety switches also work like this.
What is the evidence that an electrical circuit is closed?
When that circuit has no breaks. It is an endless path of current flow.
What is a closed switch?
A normally closed switch is a switch that is normally closed. When you operate it, it opens.
Is the pressure switch high Normally open or normally close?
A pressure switch can be normally open or normally closed. It depends on how it was made. The NO/NC should be marked somewhere on the switch. A pressure switch can be normally open or normally closed. It depends on how it was made. The NO/NC should be marked somewhere on the switch.
Does radiator cooling fan switch normally open or closed in 96 Camry?
normally closed
How does an SPDT switch work?
An SPDT (Single Pole, Double Throw) switch has three terminals: common, normally open, and normally closed. When the switch is in one position, the common terminal is connected to the normally open terminal, and when it is in the other position, the common terminal is connected to the normally closed terminal. This allows the switch to change the connection between two circuits or components by flipping the switch.
What are normally closed Switch?
this means having a low resistance measurement ; average 0.5 ohms, across 2 contacts of a switch which is normally a low value or short circuit when the switch is physically closed.
What is the difference between a fail open valve and a fail closed valve?
Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.
Is the ac high pressure switch Normally open or normally close?
The AC high-pressure switch is typically a normally closed (NC) switch. This means that under normal operating conditions, the switch remains closed, allowing current to flow. If the pressure becomes too high, the switch opens, cutting off power to the compressor to prevent damage.
What does NC indicate when shown on a switch?
That means the switch is Normally Closed (NC). You press an NC switch to break the flow of current.
Why would fuel cutout light on dash light and cutout switch not tripped and car will not start?
is the cutoff switch a normally open or normally closed switch ? If it a normally closed switch as it should be then the switch will need to activate with the ignition in order to supply fuel. There could be a problem with the fuel cutoff relay or a fuse. Also if you are using a non factory key then this might also happen.
How can you make a light bulb go off when a door is opened?
Use a normally closed (NC) contact switch rather than a normally open (NO) momentary contact switch.
Difference between TPN switch and TP and N switch?
no difference whatsoever
What is the difference between open and close switch?
In an open circuit no cuttent can flow so the switch would have to be in the off position- the switch is open and not completing the circuit. A closed circuit is one where current can flow all the way through, the switch would have to on and therefore closed.
