Pressure Switches
We have developed a new system to order your pressure switches. The new system is designed to reduce the confusion between different pressure ranges and different “P” ranges (eg. PDA, PEHA etc.).
Now all pressure switches begin with the letters PS, followed by codes for pressure, connection, switch, electronic connection, body, diaphragm and any other special requests.
If we don’t stock it, we will source it!
We now have 3 main ranges of pressure switches. They are high quality and designed for a range of pneumatic and hydraulic applications.
We carry a wide range of switches to cover most applications. See below for an updated list of our inventoried switches. If your required switch is not listed, please don’t hesitate to contact us as we can source it.
Low Range Pressure Switches
With ranges varying between 0.04-10 bar. The majority of these switches have a maximum overpressure of 24 bar, however we do stock some heavy duty low range pressure switches for large spikes in system pressure.
See here for a list of our current inventoried pressure switches.
If your required switch is not listed here, please let us know and we can source it for you or find an alternative.
NPT conversions available.
Please contact us for data sheets on individual switches.
Medium Range Pressure Switches
With ranges varying between 1-120 bar. These pressure switches have a high maximum overpressure to withstand high pressure systems.
See here for a list of our inventoried pressure switches.
If your required switch is not listed here, please let us know and we can source it for you or find an alternative.
NPT conversions available.
Please contact us for data sheets on individual switches.
High Range Pressure Switches
With ranges varying between 17-400 bar. These pressure switches have a high maximum overpressure to withstand high pressure systems.
See here for a list of our inventoried pressure switches.
If your required switch is not listed here, please let us know and we can source it for you or find an alternative.

PJDA Differential Pressure Switch
Field Adjustable
Inline Mounting
Compact Size
Dual Diaphragms
Differential from 10 – 50 psi (.7 to 3 Bar)
System Pressures to 500 psi (35 Bar)
The PJDA differential pressure switch represents a breakthrough in compact, low system pressure differential switches. The sensing diaphragms only operates when the difference between the High and Low rises or falls to the adjusted conditions.
The set point can either be factory set or field adjustable through the low pressure port. The adjustable range is dependent upon the spring rate which is factory installed.
Standard features of the differential switch include a 5 amp snap action micro-switch and SPDT circuit (3 wire). The electrical connection is DIN 43650A either with a cable connection or 1/2in. conduit.
Optional ports and diaphragm materials are available on request.
G75-DP-1 Digital Pressure Gauge Switch
Differential Pressure (DIF) and Set Pressure (SET)
2 ft/60 cm cable plus 4 wires
2″ (inch) 52mm diameter
Internal memory to retain “Set-up data” at power down
4 Modes: Auto, Manual, PSI/BAR Selection, Zero Set
5 Modes: Auto, Manual, Set Pressure or set time for automatic filter backflush
Differential Switch Type 604
The type 604 pressure switch is used as a Δp flow switch in
ventilation ducts for the control of filters and fans, and in
primary and secondary control systems for the control of air
dampers.
The 604 pressure monitoring switches are also ideally suited
to protect heating coils from overheating and for monitoring
industrial air cooling circuits.
