New interpretation of a rocker switch Based on the JUNG switch of the early years, the LS 1912 rocker switch turns the switching mechanics into a new experience. The switch mechanism is designed so that the cover closes flush with the frame. Only the rocker lever rises out of the unit as style element. JUNG transfers the many years of experience in metalworking into an elegant selection of materials – from aluminium, via stainless steel and brass to chrome.
