OTTO P2 3-Position Momentary Action, One or Two Step Commerical Pushbutton

Electromechanical Pushbutton Switch with Three-mode Design.

OTTO’S unique 3-position P2 pushbutton offers two levels (steps) of momentary switch action plus “off” for applications requiring three modes of operation. Each detent operates an independent set of SPDT contacts rated to 5A @ 28Vdc or 125Vac wrapped up in a watertight and dust tight 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 the commercial market, the P2 also works well in numerous military applications.
