Model 6PSVac
The Model Series 6PS Vacuum Switch is constructed using a rugged cast aluminum housing that incorporates Solon's standard "frictionless" switching mechanism actuated by a diaphragm. The housing can be specified 6PSW, watertight; or 6PSX, explosion proof. The housing is large enough to accommodate up to four full size S.P.D.T. electric switches. These electric switches are available in a variety of configurations including adjustable switch differential (dead band), D.P.D.T., High-Low operation, and manual reset. In addition many switching configurations can be supplied with electric switches that have:
- Low switch differentials (dead band).
- High direct current ratings.
- Gold contacts.
- Hermetically sealed contacts.
The standard vacuum-sensing element uses a strong Buna N elastomer diaphragm. Other diaphragm materials are available.
