Forbes & Lomax’s Rotary Dimmers push to switch on and off and rotate to dim and brighten. The dimmers are based on the elegant nickel and brass switches of the 1930s. These simple, timeless dimmers are a refined detail in any interior.
Rotary Dimmers can be mixed with Toggle Switches and push buttons on the same plate. Contact us for custom configurations.
Established in 1987, Forbes & Lomax is a UK based company with a reputation for high quality design amongst architects and designers.
