Hermetically Sealed Switch
We recommend hermetically sealed
switch elements for improved reliability.
The hermetically sealed switch provides
uncompromising contact protection in
harsh or corrosive environments. The
Ashcroft 400 Series is also approved for
installation in Division II hazardous
areas when supplied with hermetically
sealed contacts.
Features:
• UL-recognized component, guide
WSQ2, File E85076
• All-stainless steel welded construction
RECOMMENDED PRACTICE:
All controls should be selected consider-
ing 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.
