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.
