The K16-411 is a compact 16mm rotary selector switch designed for panel-mounted control applications where a reliable, maintained two-position selection is needed. Featuring a round head and smooth rotary action, it lets users toggle between two fixed states, ideal for mode selection, on/off control, or manual override functions in control panels, machinery, and DIY electronics enclosures.

Built with an SPDT (1NO 1NC) contact configuration, this switch offers straightforward wiring for both normally open and normally closed circuit paths from a single unit, making it versatile for a range of switching logic requirements. The maintained (latching) action means the switch stays in its selected position until manually turned, providing stable and predictable operation without the need for continuous holding.

Housed in a rugged construction rated IP65 for water and dust resistance, the K16-411 is well suited for both indoor panels and harsher environments where exposure to dust or moisture is a concern. Its 16mm panel cutout makes it a convenient drop-in replacement or addition to standard control panels, industrial equipment, and hobbyist project enclosures alike. This switch is a solid pick for makers, panel builders, and engineers looking for a compact, dependable rotary selector for everyday switching tasks.
