But do you know when the electric switch was invented or who invented it? To find out the answers to these questions and more, read the following FAQs:
When was the electric switch invented?
The first quick-break technology electric switch was invented in 1884. Before the invention of the quick-break technology electric switch, a switch’s contacts developed electrical arcing, posing safety issues. The "quick break" technology ensured that there was not enough time for an arc to form. This increased the life of the switch and made it safer.

The technology behind the electric switches remains the same even today. Across the world still domestic and industrial electrical switches are based on the same technology.
What is the difference between modular and non-modular switches?
The conventional switches had exposed metal screws, which posed a safety risk. The modular switches do not have any metallic parts on the switchboard.
Are modular switches good?
Made of polycarbonate, modular switches are fire resistant and have a more extended life expectancy than plastic and porcelain switches.
How does a dimmer switch work?
Dimmer switches let you adjust the brightness of the room, thus giving better control over the look and feel of the room. Dimmer switches should always be used with dimmable lights.

- Rotary dimmers: They can be manually turned into dim lights. The dial can be rotated to increase or decrease brightness.
What is an outdoor electrical switch?
Outdoor electrical switches are designed to withstand exposure to wind and water. Always look for a weatherproof rating when buying outdoor switches.
