The answer to 'price of dimmer switch' is that the cost of a dimmer switch can vary widely depending on factors like the type of switch, brand, features, and where you purchase it. Typical ranges for basic dimmer switches are generally between $10 to $50, but more advanced or specialty models can cost $100 or more. The installation cost can also add $50 to $150 if you hire an electrician to do the work.
The main factors that influence the price of a dimmer switch include the type (rotary, slider, smart/connected), wattage capacity, style/finish, and brand name. Dimmer switches for LED lights may cost more than those for incandescent bulbs. Hiring a professional electrician to install the dimmer will also increase the overall cost compared to a DIY project.
