Dwyer 195002F Pressure Switch

A pressure switch is a mechanical device used to control or monitor the pressure of a fluid (liquid or gas) within a system. It operates by sensing changes in pressure and, based on those changes, either opens or closes an electrical circuit to initiate a specific action.
