Traditionally, two switches can be connected together with a crossover cable.
A crossover cable should be used whenever two of the same network devices need to be connected together. e.g. Connecting a router to another router, a switch to another switch or a PC to another PC.
Using a crossover cable is not always necessary however. Most new network devices include a feature named Auto-MDIX (Medium Dependant Interface Crossover). Auto-MDIX detects what type of cable is connected and automatically changes its own configuration to enable data transmission to the other device. i.e. It does not matter if you use a straight through cable or crossover cable on Auto-MDIX enabled devices. Both will work.
Yes you can connect two or more switches together
You need a crossover cable in order to accurately connect them though.
Two switches in series would be an analogue representation of a solid-state AND logic gate.
Two equipments of the same type - two computers, two routers, two switches - should be connected with a crossover cable.
If, by "HUSwith" you mean "hubs with", and by "hub" you really mean "hub" and not "switch" then you'll have either three collision domains (if the three hubs are not connected to each other) or a single collision domain (if the three hubs are connected to each other). Replace the hubs with switches and you'll have 30 collision domains, if the switches are not connected, or 32 or 33 if they are (depending on how the inter-switch connections are made: two switches connected to a common third vs. each switch connected to both the other two).
surface type switches is a switches in the wall while flush type switches is connected in the outlet of appliances. this is the best answer for that!
It provides switching for a single wire. It has one input and one output. When the switch is open (Off) the input is not connected to the output. When it is closed (On) the input is connected to the output.
Two different networks are connected by a router. Switches are used to connect network devices within networks.
Not all switch have there own power source, some of the switches are connected with two or more power sources so it is best to have additional switches to avoid a blowout.
I have trouble understanding your question. But I think you are saying that you have two switches that control one light and want to know why it is not working. More than likely is that you have two way switches instead of 3 way switches installed. 3 three switches cost a little more and are a little more difficult to install but if you recently replaced these switches you may have replaced them with the wrong type.
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
No. For any 3 way switch installation you need 2 "travelers" between switches and these conductors cannot be used for any other purpose. The 3rd wire is used for a neutral or switch leg, depending on the needs of the circuit, but is not connected to both switches. The neutral is not connected to either switch.
When there's two switches connected to the same lamp it's usually because the lamp was meant to be able to be turned on and off from two different places. Useful in corridors and stairs and places like that. Or it can be that it originally was a fixture with more than one bulb in it. Two switches meant you could get different amounts of light out of the same fixture.
It is becoz phase shud be control by switches, and also pahse contain voltages of any ranges.
