2 Lights 1 Switch Wiring
Learn how to wire 2 lights with 1 switch using a parallel circuit. This guide includes diagrams, FAQs, formulas, and real data to simplify your electrical project.

control two bulbs one switch
In order to connect two lights to one switch, a parallel circuit is to be used where both switches are connected to a live carrier feeding the two bulbs. This provides an equal amount of brightness, and also, you can switch both lights off and on at the same time. It is easy, secure, and efficient and can be used in home installations of lighting. The guide gives diagrams and formulas, data tables, and frequently asked questions that will enable you to begin your work with the minimal number of tools and have all your answers.
Wiring Logic:
- Total Load (W) = Bulb1 Power (W) + Bulb2 Power (W)
- Total Current (A) = Total Load (W) ÷ Voltage (V)
one switch for two lights
Lights on a single switch is a common and pretty straightforward procedure ordinarily utilized within homes and business wiring. Here, both the lights are connected in parallel, and both of them can be switched on/off with a single switch. This kind of circuit will ensure every light point gets the full voltage and brightness, thus it is economical and very useful in places such as passageways and washrooms or where people have more than one point where lights can be used. Wiring style is the way in which one completes the phase (live) cable by using the switch and the way in which he branches the return wires to the lights into different wires. When this is done, the right cables have to be used, and the right junction boxes have to be used, and it has to be properly insulated so that there is safety that is created. This connection is perfect when it comes to do-it-yourself enthusiasts and electricians who deal with simple lighting systems only.
bulb connection with single switch
| Bulb 1 (W) | Bulb 2 (W) | Voltage (V) | Total Load (W) | Total Current (A) |
|---|---|---|---|---|
| 60 | 60 | 230 | 120 | 0.52 |
| 40 | 100 | 230 | 140 | 0.61 |
| 100 | 100 | 220 | 200 | 0.91 |
| 75 | 75 | 240 | 150 | 0.63 |
