LIMIT
SWITCHES
These subminiature sealed switches are contained in a rugged
aluminum housing with choice of lever, roller or plunger. Featuring
the B5 series basic switch, the P6-3 series is able to switch up to
10 amps. The high contact pressure and superior wiping action of
the OTTO design also makes the P6-3 series an excellent choice
when switching logic level loads.
Sealing against water and other liquids is per MIL-PRF-8805. Wire
leaded models feature potted leads. The solder terminals are
epoxy sealed.
