Lovato GX1683U is a 16 A single-pole four-position multi-step rotary cam switch with 1-2-3-4 switching, front mounting, black handle and a 48 × 48 mm front plate.
£39.60
The Lovato GX1683U is a compact multi-step rotary cam switch designed for reliable manual switching and selection of industrial electrical circuits. Part of the Lovato GX series with square-shaped contact blocks, this model provides a 1-2-3-4 multi-step switching sequence with a single-pole configuration and a conventional free-air thermal current rating of 16 A.
Designed for front mounting, the GX1683U features a black rotary handle and 48 × 48 mm front plate, making it suitable for installation on electrical panels, machine control stations and industrial equipment. The four selectable positions provide straightforward manual selection where a circuit must be switched progressively between multiple operating states.
The GX16 platform combines compact dimensions with robust electrical performance, including a rated insulation voltage of 690 V, rated impulse withstand voltage of 6 kV and an AC-1 / AC-21A operational current rating of 16 A. Front protection to IP65 makes the switch suitable for industrial control-panel applications where resistance to dust and water ingress at the operator interface is required.
Rotary cam switches provide a robust mechanical method of selecting between predefined electrical circuit configurations. Internal cam mechanisms operate the switch contacts as the handle is moved between positions, making these devices suitable for repeated manual switching of main and auxiliary circuits in machinery, control panels and industrial installations.
The Lovato GX1683U uses switching diagram 83 to provide a 1-2-3-4 multi-step sequence on a single pole. Its compact GX construction, 16 A rating and front-mounted 48 × 48 mm operator make it a practical solution for applications requiring clear four-position manual circuit selection.
