No good way to answer this. A 3-way light switch has one wire coming to it, two wires run to the second switch and one back out of the second switch to the light. At any point, any one of the terminals may be "hot". The only one always hot is the first single terminal that is the power source.
What else can I help you with?
How can you tell if the switch that you have is a 3 way or not?
You can tell if a switch is a 3-way switch by looking at how many terminals it has. A 3-way switch will have three terminals, including a common terminal and two traveler terminals. It is designed to control a light fixture from two separate locations.
How many terminals does a two way lighting switch have?
A two-way lighting switch typically has 4 terminals: two terminals for the switched circuit and two terminals for the incoming power supply.

How many terminals does a one way lighting switch have?
Two, and possibly a ground. The ground will be clearly marked with a green colored screw.
How do you hook up an overhead light in the kitchen to a two way switch?
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.

How many terminal does an intermediate way lighting switch have?
An intermediate or 4 way light switch has 4 terminals + 1 ground terminal.

What does a 4 way switch do?
For starters, a four way switch must be connected to either a four way switch or a three way switch on either side. Said differently, here are some common combinations: 3way---------4way-----------3way 3way---------4way-----------4way------------3way 3way---------4way-----------4way------------4way----------------3way etc. If you are using a four way switch anywhere in a circuit both ends must have three way switches. You can use as few as one four way between the three ways, or as many as you would like. First of all, connect your white (neutral) wire straight through every box, from the power source to the light fixture being controlled. That neutral has nothing to do with the switches. On your three way switches you will see two bright screws and one dark. (Excluding the green grounding screw). One three way switch will have its dark screw connected to the power source. Two wires will run from the bright screws to the next box (the 4 way switch box). Those two wires will connect to the two bright screws on one side of the four way. The four way also has dark screws, but two of them. Connect two wires to these two dark screws, and run them to the next switch box. If the next switch box is another 4 way, repeat this again and again until you get to the last switch (a three way). Wire the last three way as follows: the two wires coming from the previous 4 way go to the bright screws. The hot wire feeding the light fixture will be the one to connect to the single dark terminal of the last 3 way switch. That's it! As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How many states does a switch have?
A switch has two states, on and off.
How many terminals do a light bulb have?
A standard light bulb typically has two terminals: the base terminal and the tip terminal. The base terminal connects to the power source, while the tip terminal is used for grounding. In some specialized bulbs, such as those with multiple filaments or features, there may be additional terminals.
How many terminals does Heathrow currently have?
Heathrow has two terminals
How many conditions or states can a light switch be in?
Most light switches can be in two states, on or off.
How many line conductors are installed between the switch and light fixture?
One. A typical "two way" ON-OFF light switch is a Single Pole Single Throw (SPST) switch with two terminals. It is wired in series with the fixture: that is, the power circuit is routed from the breaker to one side of the switch. The other side of the switch is connected to the "phase" or "power" terminal of the fixture. In a 115VAC single phase circuit, the other terminal of the fixture is connected to neutral. A "three way" switch circuit consists of two switches in different locations, each of which is a Single Pole Double Throw (SPDT) switch with three terminals. A typical use would have one switch at the top and the other at the bottom of a set of stairs. For the sake of clarity, we can label the "common" terminal on a SPDT switch the "C" terminal. This terminal is internally connected to one of the other two terminals, call them "A" and "B", depending of the position of the switch. A three way switch is connected with the circuit breaker connected to the "C" terminal on either switch. Conductors connect the "A" terminal on one switch the the "A" terminal on the other switch and the "B" terminal on one switch the the "B" terminal on the other switch. The remaining "C" terminal is connected to the "phase" or "power" terminal of the fixture. The other terminal of the fixture is connected to neutral. Note that, in either case, there is no neutral wire connected to the switch. Ground conductors do connect to the chassis of the switch box and the fixture, but they do not carry current and do not affect the operation of the circuit.
