A single pole switch is the ordinary switch that is used to turn the lights off and on in your home.
A double throw switch is also known as a 3-way switch in North America.
A double throw switch has a single pole connected to a common screw or terminal, often black. There are 2 additional screws or terminals, often brass colored. In one switch position this pole is connected to one of these screws or terminals and in the other position it connects to the other screw or terminal.
If you think of a Baseball diamond as an example for this switch, in one position the base line from home to first is hot. In the other position the base line from home to third is hot.

What is a two way lever switch?
In electrical terminology it is known as a single pole double throw switch.
What is dpst switch?
Double pole Single Throw switches are sometimes called DPST switches. Assuming the circuit is single phase two wire system, DPST - are used to isolate the ciruit. Isoloation occurs on both terminals hence it is called double pole. This isolation occurs at only one end in the circuit, hence it is called single throw.
How did a 'three-way switch' get its name?
"How does a single pole switch differ from a three way?" is a trick question often asked to catch-out new trainee electricians because the common but mis-named "three-way switch" is actually a single pole, double throw switch, i.e. it is only a 2-way switch, not a 3-way switch.A pair of "3-terminal, single pole, double throw" switches are often used to hook-up two separate light switches to control one light or one set of lights.A proper "3-way switch" would be capable of being switched to 3 different positions and could have one, two or more poles. Each pole could be either single- or double-throw.The same answer put in a different wayDespite the fact that the name "3-way switch" is often used to describe it, if it is of the type that has just one pole that can only be physically switched 2 ways, the name "3-way switch" is quite wrong for that particular switch. A "3-terminal, single pole, double throw" switch" is a more accurate description for it.Comment'Three-way switch' -American term. 'Two-way switch' -UK term for the same type of switch. Used to operate a lamp from two different locations.
What does common mean on a light switch?
On a single pole single throw there is no common terminal. On a single pole double throw it is the terminal that is common to both the top and bottom terminals. The "hot" wire is connected to the common terminal so that when the switch is in the up position that terminal becomes energized and there will be no no voltage on the bottom terminal. When the switch is in the down position the bottom terminal becomes energized and there will be no voltage on the top terminal. In relays thisis known as a C form configuration.
What is a one gang two way switch?
It switches two separate wires with one switch throw. <<>> It is two individual single pole single throw switches mounted side by side and are enclosed in a single enclosure. The single enclosure is called a two gang junction box.
How is an electrical double pole switch correctly wired?
For a single throw, double pole switch, each section is wired to the individual items to be controlled. For a double throw double pole (220) set up, both hot wires are run through the switch.
What does spdt switch stand for?
Single-pole, double-throw. The switch directs a single input to two possible outputs.
What is a two way lever switch?
In electrical terminology it is known as a single pole double throw switch.
What does the abbreviation DPDT stands for what type of switch?
DPDT stands for Double Pole Double Throw. It is a type of switch that has two separate circuits controlled by a single mechanism, allowing the switch to control two independent sets of contacts.
How do you wire a DPST switch?
A double pole single throw switch. used to switch two lines at the same time.
What is the difference between single pole double throw switch and single pole single throw switch?
A single pole double throw (SPDT) switch has three terminals: one input and two outputs. It can connect the input to either of the two outputs. A single pole single throw (SPST) switch has only two terminals: one input and one output. It simply opens or closes the circuit.
What is the difference between iron clad double pole switch and double pole single throw switch?
An iron clad double pole switch is a heavy-duty switch designed for outdoor or industrial use, featuring a sturdy protective casing. A double pole single throw switch is a type of switch that can control two separate circuits simultaneously, with each pole connecting or disconnecting a separate circuit. Therefore, the main difference is in their design and usage - one focuses on durability and the other on functionality.
What is the difference between a single pole switch and a double pole switch?
A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
What is a DPST switch?
DPST is short for double pole, single throw. Double pole means that the unit contains two identical switches, side by side, and operated by one single toggle or lever. This means that two separate input wires can be controlled by a flick of one toggle. Single throw means that each switch can make or break a circuit; it can connect the input wire to the output, or not. It can't connect to one or other of two output wires, switching between them. A DPDT switch is also used for a disconnecting a 240 volt supply from a 240 volt load. Some other types of switches are Single Pole Single Throw (ordinary light switch), Single Pole Double Throw, Double Pole Double Throw, Triple Pole Single Throw and Triple Pole Double Throw
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.
A SPST switch is an example of what circuit?
It stands for Single Pole Single Throw
Is it difficult to differentiate a SPST switch from a SPDT switch?
It is not difficult to differentiate between a SPST (Single Pole, Single Throw) and a SPDT (Single Pole, Double Throw) switch. A SPST switch has one input and one output, while a SPDT switch has one input and two possible outputs. This difference can typically be visually identified by looking at the number of terminals on the switch.
