Every room in a house has one or more light switches that control the electrical outlets or lighting fixtures. All pendant lights, wall sconces, chandeliers, and recessed fixtures are usually turned on and off when we flip a light switch that we usually positioned near our doorway or bed. Without mounted light fixtures in our rooms, a light switch usually controls the electrical outlet where we plug our floor lamp. We do not give much thought about switches but knowing how light switches work and what type of different light switches are available is essential so that if we need to replace or repair any light switch, we would have an idea which one suits our needs the best.
We can increase the efficiency of light bulbs with the use of different switches. Some of the switches that improve the efficiency of light bulbs and ease users are light switch dimmer, light switch timer, light switch wifi, and light switch Bluetooth. Let’s look at what these switches are and how do they benefit us in detail.
- SINGLE-POLE ON/OFF LIGHT SWITCH
- LIGHT SWITCHES DIMMER
- LIGHT SWITCH TIMERS
- LIGHT SWITCH WI-FI
- LIGHT SWITCH BLUETOOTH
What is Single-Pole On/Off light switch?
A single-pole switch turns the light on and off from only one wall location. That is why these light switches are also called single location switches. Single-pole switches consist of ON/OFF markings that are printed on the toggle lever of the switch. No other switch has such markings.
In single-pole ON/OFF light switch, there is a spring-loaded metal gate that is inside the switch that closes and opens the electrical circuit leads toward the light fixture. When toggling the lever to ON position, the gate closes and completes the circuit; the power is then flowing through the switch and reached to the light fixture. When you toggle the level to OFF position, the gateway opens and interrupts the power flow toward the light fixture.
Inner gateway has a different design. Older types of inner gateways are purely mechanical having a metal arm that gets controlled by springs. As the spring loses its resiliency, these types get wear out. To conduct electricity, new kinds of switches use a vial of mercury inside. The new type of switches does not have snap characteristics when the lever gets flipped. They are also more durable than the mechanical type of switches. They are marketed as quiet switches and are more expensive than the mechanical ones, but they wear out rarely which is a plus point in their durability.
What are Dimmers?
In homes, adjustment of light is a constant struggle. It is often difficult to adjust the right amount of light in a room or a house overall. Often people want to include the option of low and full lighting which adds up the cost. Dimmers are the best solution in such situations. A light switches dimmer restrict the flow of current to a bulb with the use of CL or TRIAC technology. In light switches, dimmers are such devices that get connected to the light fixture and lower the brightness of the light.
We can reduce the intensity of light by changing the applied voltage waveform to the lamp. Dimmers come in different size ranges, i.e., from small units for domestic light switches to high power units for architectural lighting or theatrical lighting installations. For domestic users, we can control dimmers directly and also we can control them with a remote. However, digital control systems like DALI or DMX controls modern and professional dimmers.
Benefits of Dimmers
- Energy savings: Traditional light switches give you only two options either 0% electricity or 100% electricity. This way the usage of electricity increases so as your electric bills. By using dimmer, you can reduce the usage of energy, and hence electric bills get reduced.

So, whether it is a movie night or bright day, dimmer switches let you set the tone of your room according to your requirements.
What are light switch timers?
Another way to manage home lightings is light switch timers. Timers allow the bulb to operate for a specific amount of time. There are two versions of light switch timers in the market. The first one is manual-setting light switch timer and second is factory-preset light switch timers. Manual-setting light switch timer allows you to on-off period as many times as you required to set within 24 hours. Whereas in the factory-preset light switch timer, each time you turn on the switch, you get to choose the period for your OFF command.
