These pressure switches are used for monitoring system pressure to sound an alarm, operate a warning light, or cut off the electrical supply to a pump or machine as soon as the pressure gets above or below the optimum level. The type 12 pressure switches are particularly suitable for use on compressed air systems, or to monitor water pressures or provide cut-out on pressure failure in lubrications. They can be used on all non-corrosive fluids except for those with high viscosity.
