A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires. In other words its like two simple switches controlled by a single actuator.
How To Wire A Double Pole Light Switch Quora
Double pole switch diagram. The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts. Double switches sometimes called double pole allow you to separately control the power being sent to multiple places from the same switch. It has four terminals. Fig 12 dpdt terminal diagram. A double switch allows you to operate two lights or appliances from the same location. Double pole double throw toggle has 2 input terminals and 4 output terminals.
The difference between a single and double pole switch is that the latter controls two circuits at the same time. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 4 modes. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. 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. For 20 32 40 45 50 amp double pole switches. Here pole indicates individual input circuit and throw indicates the output circuit.
It reveals the elements of the circuit as streamlined shapes and also the power and also signal connections between the gadgets. When is the switch is one way the lamp is on and the led is off. 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. Do not connect this switch directly to a ring circuit. This is a double pole double throw dpdt momentary illuminated momentary rocker switch it has one ind lamp at the top. Two for incoming hots and two for outgoing hots.
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. When the switch is flipped the other way the led is on and the lamp is off. Below is an example of a circuit which utilizes a double pole double throw switch. Collection of leviton double pole switch wiring diagram. 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. For example you might want to turn on a bathroom light separately from the ceiling fan.
Circuit a is connected to a lamp and an led. Make sure that the load cable is connected to the appliance to be switched and that this switch is earthed. 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 wiring diagram is a streamlined conventional photographic representation of an electrical circuit. 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.
You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes.
