We manufacture what we sell.
R & D Electronics is a South African manufacturer of domestic and commercial light dimmers, built at our own factory in Montague Gardens, Cape Town, and distributed nationwide.
Because we design and assemble the boards ourselves, spares stay available, custom loads are possible, and technical questions get answered by the people who build the products.
