Product Introduction
Air Compressor Pressure Switch Bracket Assembly - Dual Gauge Manifold with Automatic Cut-In/Cut-Out Control and Outlet Valves
Automatic Start/Stop Pressure Switch · Dual Pressure Gauges · Two Brass Outlet Ports with Red Lever Ball Valves · 8 Bar / 120 PSI Working Pressure - Universal Replacement Assembly for Reciprocating Workshop Compressors
Air compressor bracket tape switch
The pressure switch assembly is the operational nerve centre of a reciprocating air compressor - monitoring receiver tank pressure in real time and automatically signalling the motor to start when pressure drops below the cut-in set point, and to stop at the cut-out pressure. A failed or miscalibrated switch produces the most disruptive compressor failures: a switch that cannot cut out leaves the motor running continuously against a safety valve; a switch that cannot cut in leaves pneumatic tools without air mid-operation.
This bracket assembly integrates the automatic pressure switch, dual pressure gauges, two brass outlet ports with red lever ball valves, and a safety unloader valve on a single black manifold bracket that threads directly onto the receiver tank outlet. The black ABS switch body features a red manual override lever for manual start/emergency stop, with cut-in/cut-out set points adjustable through the switch top without removing the assembly. Two black-bezel gauges with white dials display tank pressure and outlet pressure simultaneously. The two brass outlets accept standard quick-connect couplings and are individually isolatable with red lever ball valves - one closed for single-tool operation, or both closed during maintenance.
Technical Profiles & Materials
Black ABS Automatic Pressure Switch Body with Adjustable Cut-In and Cut-Out Set Points The switch is a spring-loaded diaphragm mechanism that senses tank pressure through the manifold inlet and opens or closes the motor supply circuit contacts at the configured thresholds. The black ABS housing encloses the switch contacts, sensing diaphragm, and dual adjustment spring columns - the larger column controls cut-out pressure, the smaller adjusts the cut-in/cut-out differential - both accessible through the top with a flathead screwdriver for field calibration without removing the assembly. The red manual override lever allows emergency stop, safe maintenance isolation, or manual start when the tank pressure sits between set points.
Dual Black-Bezel Pressure Gauges for Simultaneous Tank and Outlet Pressure Monitoring Two round gauges with black bezels and white dials are mounted to provide simultaneous visual confirmation of receiver tank pressure and regulated downstream outlet pressure - information a single-gauge assembly cannot deliver without interrupting tool operation to redirect the connection. The tank gauge reads directly from the manifold inlet, confirming correct switch cut-in/cut-out behaviour and tank charge retention between pump cycles. The outlet gauge reads downstream of the pressure regulator, showing the actual working pressure delivered to tools - which may differ from tank pressure depending on regulator setting and flow demand. The dual-gauge configuration eliminates guesswork when diagnosing pressure regulation faults or adjusting working pressure for different tool requirements.
Brass Dual Outlet Fittings with Red Lever Ball Valves and Manifold Body The two brass male outlet fittings are machined from solid brass for corrosion resistance in the oily, humid compressed air environment and threaded to accept standard quick-connect sockets without adaptors. Each outlet is individually controlled by a red lever ball valve - a quarter-turn valve whose lever position provides unambiguous open/closed visual confirmation that cannot be misread in dim workshop conditions. The black manifold body connects switch inlet, gauge ports, regulator, and both outlet valves in a single leak-tested assembly, eliminating the multiple threaded joints between individually sourced components that are each a potential leak point in a high-cycle-count compressor installation.

Products Application
Pressure Switch Assembly Replacement on Existing Workshop Compressors
Workshop technicians replace the complete pressure switch bracket assembly when a failed switch prevents the compressor from automatically cycling - presenting as continuous motor run-on past target tank pressure, failure to restart after a pressure drop, or erratic cut-in/cut-out behaviour producing inconsistent working pressure at the tool outlets. The replacement assembly threads directly onto the receiver tank outlet port, the motor supply cable is reconnected to the switch terminals per the wiring configuration on the switch body, and cut-in/cut-out set points are adjusted through the switch top before a commissioning pressure cycle confirms correct automatic start/stop behaviour. Replacing the bracket assembly as a complete integrated unit avoids the separate sourcing .
Cut-In / Cut-Out Pressure Calibration and Switch Inspection on the Workshop Workbench
Before installation, the technician inspects switch contact condition, verifies diaphragm housing integrity, and checks the gauge needle zero position on both dials - a gauge reading above zero with no pressure applied has a damaged Bourdon tube that will give misleading tank pressure readings during operation. Cut-in and cut-out set points are pre-adjusted with a flathead screwdriver on the spring columns through the switch body top before mounting, reducing the pressure test cycles required to confirm correct calibration on the live compressor. Both red lever ball valves are cycled through their full open-and-close travel to confirm smooth quarter-turn operation and seated shut-off before the assembly is threaded onto the tank outlet - a stiff or leaking valve is identified before pressurisation, not after.
Dual-Outlet Independent Tool Supply in Multi-Operator Workshop Compressed Air Systems
With the assembly installed and pressurised, the two independently valved brass outlet ports allow a single compressor to supply two separate air tool operators simultaneously - each operator controlling their own outlet valve to connect, isolate, or disconnect their tool without interrupting the other outlet's flow. The dual-gauge configuration is particularly valuable in multi-operator workshop settings where tool inlet pressure requirements differ between operators - one outlet supplying a high-flow pneumatic grinder while the other feeds a lower-pressure spray gun - allowing simultaneous monitoring of both outlets to confirm that neither downstream pressure deviates outside the tool's rated operating range.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
