J40 Series Overview
Skeleton Pressure and Vacuum Switches
The J40 can be utilized in OEM applications where compact size and performance are required. The sealed bellows sensor provides
a “leak-free” sensor for applications where elastomers are unacceptable. Proven reliability involving sterilizers, plasma-cutting, anesthesia equipment, and even protective switching devices for power equipment, have made the J40 a versatile OEM pressure switch.
