Is it difficult to differentiate a SPST switch from a SPDT switch?
No it is not hard to tell them apart. A Single Pole Single Throw switch will go directly from the on position to the off position breaking the circuit. This is the type of switch that is used in homes for lighting control. A Single Pole Double Throw switch will usually have a stop indent which is the off position mid way through the throw. This is the switch that is used for a transfer switch when using a stand by generator in the system. The full up (on) position is usually connected to utility power. The full down (on) position is usually connected to the stand by generator.
What does the abbreviation DPDT stands for what type of switch?
A DPDT switch is a Double Pole Double Throw switch
What is the difference between single pole double throw switch and single pole single throw switch?
US Single-pole switchIn the US, the standard "single-pole" light switch is single-pole single-throw, with only 2 terminals. In the ON position it connects the two terminals, and in the OFF position it doesn't. The standard US "3-way" light switch (used for switching a light from two different switches) is single-pole double-throw. It has 3 terminals (hence the term "3-way"), and it connects one of those terminals to either of the other two, depending on the switch position. There's no OFF position, so the switch has only two positions.
Can a 4-way switch be used like a single pole switch. if so how is it wired?
Are you sure. They no longer produce a single pole switch in the color needed and we thought that a 4 - way could be sub'd. There is no reason that it would not work, electrically. The problem may be that it doesn't meet electrical code. If you use two terminals on the same side of the switch as you would with single pole, it should work.
What does com mean on a light switch?
In a situation where there is only one switch controlling the light or lights you normally use a spst (single pole single throw) switch that has only two connection terminals. This type of switch either connects or disconnects the two wires that are connected to the switch's terminals depending upon the position if the switch lever. The com terminal on a light switch means that it is a three way or the kind of switch used where there are two or more switches that controll the same light or lights. The three way switch is a spdt ( single pole double throw) . If you look closely you will find this designation somewhere on the switch. On the spdt switch you have three terminals, a common and two branches. In one postiion the common connects to one branch and in the second position the common connects to the other branch. If you are trying to install this switch in a situation where there is more than one switch controlling the light you must have the ability to correctly identify the common wire; if you can't do that you need help from someone who can do that correctly.

What is a single pole single throw?
It is a type of switch or relay where there is just one set of contacts. The contacts can be open or closed. There are two terminals. A standard light switch like you would find in your home is a good example of a switch with a SPST contact.
Is there a residential switch 15A rating that will allow one source to be switched to either of two loads?
Yes, a three way lighting switch will do that job. There is no off position if you use this type of switch, it will be either one load or the other on all of the time. To over come this condition you can install a single pole switch ahead of the single pole double throw (three way switch, two way switch in the UK). There is a small toggle switch that has an on - off - on positions but it is not a residential switch.

What is a 3 gang 3 way switch?
3 gang switch and you can call it 2-way switch..is a type of swithces we are using mostly in the stairs lighting ,that mean you have switch up to the stair and one down to the stair and you can switch the light on from one and switch it off from the other switch and via verse. <<>> There is no such thing as a three gang three way switch,. The nearest thing is a three gang double throw switch. It is used to supply a three phase load from two individual three phase supply sources. This is the type of manual switch that can be used for emergency power switch over from utility to generator. Three way switching uses a single pole double throw switch at each end of the circuit and a cross over switch in the center position. The center switch in a three way lighting configuration is a cross over switch and a double pole double throw switch in that position will not work.
Why does your Yamaha pw50 die when switched to the run position?
The reason your PW50 is cutting out when switched from the start position to the run position is because the contact points on the switch it self are worn down! The quick fix for this problem is to carefully remove the small plastic sliding switch block being careful not to loose the ball or spring! You will have to remove the copper contact plate with a fine flat or flat precision type screw driver and carefully tap on the 3 points on the reverse side of the contact plate again using a precision type screw driver and a small hammer.... It would be a good idea to clean the contact points on the wired contact block with some contact cleaner! Put the switch back together unplug the ignition switch (wire harness) and single black ground wire and test the switch with a multimeter just to make sure that the points are making proper contact! This is how I fix the ignition switches on the Yamaha's and other Japanese bikes with similar ignition switches!
What is meant by SPDT?
In electronics, an SPDT is a type of switch. It stands for "Single Pole, Double Throw." In America, it's known as a three-way switch.
Where is S.P.D.T. used?
In electronics, SPDT refers to a particular type of switch; a "Single Pole Double Throw" style. Other flavors I think you may recognize now are SPST, DPDT, and TPDT. It breaks down like this; the "Pole" count (single, double, triple, etc.) refers to the number of switch contact sets that are connected to the switch lever. The "Throw" count refers to the number of positions the switch lever is designed to be set to. Light switches in your house are SPST switches.
What does double pole mean on a cooker control unit?
"Double-pole" refers to the type of switch used to disconnect the cooker from the incoming household electricity supply. Only by using a double-pole switch can the cooker's connections to both the live (or "hot") and neutral supply wires be switched on and off simultaneously.
What kind of switch connects conductors A B and C with the 3 positions AC ABC and BC?
This would be a single-pole, double throw, shorting-type switch.
