The exact price you'll pay for a switch in your area will depend on factors like the type of switch (smart, dimmer, etc.), the brand, the material (plastic, metal, etc.), and whether you need to hire an electrician for installation. It's best to get quotes from local electrical supply stores or licensed electricians to get a more accurate estimate for your specific needs and location.
