ROTOTHERM
Pressure
Switches
A pressure switch actuates a corresponding micro switch contact as soon as a preset pressure is reached. Rototherm pressure switches are used in a variety of demanding industrial and technical processes, such as offshore platforms, nuclear applications, and chemical, pharmaceutical and gas transmission to name a few.
Pressures switches joined our portfolio following the acquisition of HNL Engineering in 2012, a company designing and manufacturing pressure switches and manifolds for over 60 years. The switches are built to last in the most demanding of environments.
