In other words its like two simple switches controlled by a single actuator. Below is an example of a circuit which utilizes a double pole double throw switch.
Basic Electricity Tutorial Switches
Double pole switch diagram. Double pole double throw toggle has 2 input terminals and 4 output terminals. Circuit a is connected to a lamp and an led. Do not connect this switch directly to a ring circuit. A wiring diagram is a streamlined conventional photographic representation of an electrical circuit. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 4 modes. Double switches sometimes called double pole allow you to separately control the power being sent to multiple places from the same switch.
Collection of leviton double pole switch wiring diagram. Here pole indicates individual input circuit and throw indicates the output circuit. When the dpdt switch is switched the other way flipped downward the led and the speaker are both on while the lamp and buzzer are off. When the switch is flipped the other way the led is on and the lamp is off. Fig 12 dpdt terminal diagram. The wiring diagram to the right will show how to wire and power this 12v 20amp on off on 3 way carling contura rocker switch.
The difference between a single and double pole switch is that the latter controls two circuits at the same time. For example you might want to turn on a bathroom light separately from the ceiling fan. D ouble pole switches are usually rated at 30 amps so any appliance or equipment requiring a greater power consumption have to be connected to a disconnect. A double switch allows you to operate two lights or appliances from the same location. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires.
You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes. When the dpdt switch is switched one way flipped upward in the diagram the lamp and buzzer are both on while the led and speaker are off. It has four terminals. Two for incoming hots and two for outgoing hots. It reveals the elements of the circuit as streamlined shapes and also the power and also signal connections between the gadgets. Make sure that the load cable is connected to the appliance to be switched and that this switch is earthed.
Look at picture 11 and 12 it consists of two common input terminals c e and both mechanically tied together to operate in the same way. Connect the cables as shown in the diagram. When is the switch is one way the lamp is on and the led is off. A double pole switch such as the one in fig1 is just slightly bigger than a regular switch but constructed as two single switches harnessed side by side and activated by one common toggle. This is a double pole double throw dpdt momentary illuminated momentary rocker switch it has one ind lamp at the top. For 20 32 40 45 50 amp double pole switches.
The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts.
