Description
Visual Setting Switches are particularly useful in situations where the frequent alteration of the pressure setting is
required. The Dial enables you to visually see the current set point of the switch along with enabling easy
adjustment.

Maximum Pressure
To ensure long service and life select the pressure range as follows:
Dynamic pressure applications Pmax = 75% of Range
Static pressure applications Pmax = 100% of Range
Maximum Pressure that can be applied is 125% of pressure range
Installation
The Switches can be mounted directly on the connecting thread. Sealing grooves are machined into the end
face of the parallel threads for the use with sealing washers. A mounting bracket is available if required.
Vacuum Setting
At ambient pressure the switches will be in the operated condition, consequently the wiring should be
reversed i.e NO becomes NC.
Connecting Threads
All connecting threads used in industry are available including British, American and Metric. Please state
required connection thread when ordering.
Flanged fittings are available and all types of Hygienic Fittings can be supplied assembled directly onto the
Pressure Switch. If flush diaphragms are required please consult our Technical Sales Department.
