UP TO 3 POSITIONS WITH 3 OPTIONAL, INDEPENDENT LED LIGHT POSITIONS, 1.45 X .83 PANEL CUTOUT
Used in the heavy equipment, marine, process control and
instrumentation markets the R2 rotary switch is an excellent
replacement for rocker switches offering improved visual position
indication, additional lighting options and different styling
opportunities on front panels.The R2 series is a sealed,lighted rotary
switch which snaps into a 1.45 x .83" industry standard rocker switch
panel opening. The rotary knob snaps onto a shaft and can be
installed by the panel builder for those desiring that flexibility.The R2
rotary switch provides up to 3 positions in all combinations of
momentary and maintained action. It is capable of handling loads
from logic level to 20 amps (resistive). Sealing is to IP68 (1 meter
immersion) via a shaft o-ring seal in front and a potted base in the
back. Termination options include .250" fast on, solder lug or a snap
on modular connector.The R2 offers unique lighting options including
up to three independent LED light positions which illuminate a lens
on the rotary knob. This design provides more lighting options than
traditional rocker switches, handles the full range of electrical loads
and is robust enough to survive in the most demanding applications.
