Otto 2 Position SPST Rotary Switch, 20A, Tab Terminals, Thermoplastic Housing, IP68S Rated R2AA111NNNNN

Otto R2AA111NNNNN 2 Position SPST Rotary Switch is a highly durable electrical component designed for industrial, marine, heavy equipment, and process control applications. This switch offers a robust 20A contact current rating with both momentary and maintained switch operations across two distinct positions. The device features a SPST (single pole single throw) contact configuration and is built with a thermoplastic housing that offers electrical insulation and mechanical strength.

The rotary switch is sealed to IP68S standards to provide excellent protection against dust and water ingress, incorporating a shaft O-ring seal in the front and a potted base at the rear for enhanced durability even in harsh environments. Its mechanical life rating of 100,000 operations ensures reliable long-term use in demanding industrial settings.

Designed to replace rocker switches, the Otto R2 series rotary switch offers better visual indication with up to three independent LED lighting options illuminating the rotary knob lens, enhancing operator feedback and safety. It fits industry standard panel cut-outs (1.475” x 0.875”) and connects via 0.250" fast on tab terminals for convenient mounting and wiring.

The switch maintains excellent operational stability within a temperature range from -40°C to +85°C, making it suitable for outdoor and industrial environments. The black soft-touch selector knob provides comfortable manual control and precise position selection.

Typical industrial use cases include instrumentation panels, marine control systems, process control equipment, and heavy machinery operation where reliable switching and IP68S sealing are essential for performance and safety.
