Which switch can control two circuits?
Double pole light switches
Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.
2 Answers. The answer is yes you can have 2 separate circuits in the same box (they can have a splice also but not needed in your case). The only concern would be the total box fill. Based on the NEC the wire fill would be calculated at 2.0 for each conductor for 14 gauge wire and 2.25 for 12 gauge wire.
What type of switches control lights from 2 locations?
A three-way switch is a type of light switch that allows you to control a light or other electrical fixture from two different locations in a room. Three-way switches are always used in pairs and include special wiring connections.
How do switches control circuits?
An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices: either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load.
How do I connect two circuits to one switch?
If you’ve mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail.
Can 2 circuits share the same neutral?
It is NOT permitted to share a neutral in any other situation. If you were to share a neutral with two breakers on the same leg of a panel, both circuits could draw the breaker limit (lets say 15A) making the shared neutral as much as 30A return current!
Yes, multiple circuits may exist in a junction box.
How do I wire two lights to different switches?
Run 12-gauge electrical cable between each switch and the light it controls. Pull one end of each cable through the back of one of the light fixture electrical boxes. Strip both ends of each cable with a knife, separate the wires and remove 1/2 inch of insulation from the end of each.

Is there a way to wire switches in series?
If there are more switches connected in series with electrical appliance i.e. light point, all of them must be at ON position to operate the load. If one of the single switch is open, the circuit won’t work then. How To Wire Switches In Series? The circuit will only complete if both of the switches are at ON position.
Where is the changeover switch on a motor control circuit?
On the left side of the diagram is a hand-operated changeover switch, which switches into circuit either the upper local or lower remote push-button switches. This type of circuit requires an extra contactor contact and only a simple changeover switch. Many motor control circuits use an automatic start control.
How are two SPST switches used in series?
the point of two spst switches in series is that first one acts as a “master switch” so you can cut the power without turning off the breaker. You are then free to use the second switch for normal operation. In series the lamp shall be made ON only if all the switches are ON position…
Why are there only two wires in a control circuit?
Because there is no other stop–start control and only two wires need to be run to the actuating device, is it usually referred to as ‘two-wire control’. Figure 4 is a simple two-wire control circuit. In this case the controlling device is a pressure switch, which is represented by the lower case p in the square.
