Hermetically Sealed Switch
We recommend hermetically
sealed switch elements for im-
proved reliability. The hermetically
sealed Ashcroft
® switch provides
uncompromising contact protection
in harsh or corrosive environments.
It also satisfies requirements for
installation in Division II hazardous
areas.
Features:
• UL recognized component, guide
WSQ2, File E85076
• All-stainless steel welded construction RECOMMENDED PRACTICE:
All controls should be selected
considering the media and ambient
operating conditions. Improper
application can be detrimental to
the switch, cause failure and
possibly personal injury or property
damage.
The information in this catalog is
offered as a guide to assist in
making the proper selection of
Ashcroft controls.
Additional information is available
from Control Instrument Opera-
