OTTO'S unique 3-position P2
pushbutton offers two levels (steps)
of momentary switch action plus "rest"
(or "off") for applications requiring
three modes of operation.
Each detent operates an independent
set of SPDT contacts rated to 5A @
28VDC or 125 VAC wrapped up in a
watertight and dusttight package.

The OTTO P2 series works like this:
Upon actuation, level one is reached
with a positive tactile feel transmitted back to the operator. The
operator has the option of either releasing the pushbutton, which
will return to the normal (off) position, or continuing to level two.
Upon release, the pushbutton returns to the normal position.
Designed for applications in the commercial market such as the
control of two-speed motors, the P2 also works well in numerous
military applications.
