IP68 Rotary Switches, Otto R2 Series


Used in the heavy equipment, marine, process control and instrumentation markets, the Otto R2 rotary switch is an excellent
replacement for rocker switches, offering improved visual indication, additional lighting options and different styling on front panels. The R2 is a sealed, lighted rotary switch which snaps into a 1.475” x 0.875" industry standard rocker switch panel cut-out.
The R2 rotary switch provides up to three positions in various combinations of momentary and maintained action. It is
capable of handling loads from logic level up to 20 amps resistive. Sealing is to IP68S via a shaft O-ring seal in front and a potted base in the back.
The R2 offers lighting options including up to three independent LED light positions which illuminate a lens on the rotary knob.
