HySecurity MX4112, SWITCH,PRESSURE,2250-2500 PSI
HySecurity MX4112 is a hydraulic pressure switch for select HySecurity HydraWedge SM50 and HydraSupply XL hydraulic applications. Nice HySecurity HydraWedge SM50 parts documentation lists MX4112 as "Switch, Pressure 2200-2500 PSI" in the accumulator and reservoir hydraulic section.
Current listings describe MX4112 as a pressure switch for a pump with accumulator. The user-provided description references "2250-2500 PSI," while several HySecurity-related listings show "2200-2500 PSI." Because pressure switch fitment depends on the hydraulic circuit, set pressure range, accumulator setup, wiring, port style, and parts diagram, MX4112 should be selected only after confirming the original switch and current HySecurity documentation.
What This Pressure Switch Does
The pressure switch monitors hydraulic pressure in the approved pump-with-accumulator circuit. In a compatible HydraWedge SM50 or HydraSupply XL hydraulic system, the switch helps the control system respond to hydraulic pressure reaching the specified operating range.
A failed, leaking, misadjusted, clogged, incorrectly wired, or wrong-pressure switch can cause pump control problems, no-run conditions, pressure faults, pump cycling issues, weak hydraulic response, or inconsistent wedge/gate operation. Similar symptoms can also be caused by low hydraulic fluid, contaminated fluid, a weak accumulator, failed pump pack, relief valve issue, check valve leakage, stuck solenoid valve, flow valve problem, hydraulic cylinder bypass, hose leaks, damaged fittings, controller input fault, or wiring damage.
Compatible With
Use HySecurity MX4112 only where the operator parts diagram, original pressure switch, or HySecurity documentation confirms this part number.
- Select HySecurity HydraWedge SM50 applications where MX4112 is listed as the 2200-2500 PSI pressure switch.
- HydraWedge SM50 pump-with-accumulator hydraulic circuits where the parts diagram lists MX4112.
- Select HySecurity HydraSupply XL applications where current parts listings or parts diagrams confirm MX4112.
- Repairs where the original pressure switch is marked, listed, or cross-referenced as HySecurity MX4112.
- Applications where the pressure range, hydraulic port, fitting style, wiring, controller input, pump pack, accumulator, and hydraulic circuit match the HySecurity parts diagram.
Important Compatibility Warning
Do not order MX4112 based only on the words "pressure switch." HySecurity hydraulic systems use several pressure-related parts, including pressure switches, pressure gauges, relief valves, flow valves, check valves, solenoid valves, pump packs, accumulators, hand pumps, cylinders, and manifolds.
The pressure range matters. MX4112 is commonly listed as 2200-2500 PSI, while some descriptions may show 2250-2500 PSI. Confirm the switch marking and current parts diagram before ordering. A wrong-pressure switch can affect pump cycling, accumulator behavior, pressure control, hydraulic performance, or controller response.

Technician Note
Before replacing MX4112, inspect the pump pack, accumulator charge/condition, pressure gauge reading, relief valve, flow valve, solenoid valves, hydraulic hoses, fittings, fluid level, fluid condition, wiring, connector, and controller input. A pressure-related fault is not always caused by the pressure switch itself.
If the pressure switch is replaced without correcting a weak accumulator, stuck valve, bad relief valve, cylinder bypass, leaking hose, low fluid, contaminated fluid, or damaged wiring, the same hydraulic issue may remain. Confirm that the hydraulic system can build and hold pressure properly before condemning the switch.
Before Ordering, Confirm
- The required part number is MX4112.
- The operator is a HySecurity HydraWedge SM50, HydraSupply XL, or other approved hydraulic application where the parts diagram lists MX4112.
- The repair requires the pressure switch, not the pressure gauge, pump pack, hand pump, accumulator, relief valve, flow valve, solenoid valve, or controller board.
- The correct pressure range is confirmed by the original switch marking and current parts diagram.
- The hydraulic port, fitting style, wiring, connector style, controller input, and mounting arrangement match the original installation.
- The pump pack, accumulator, relief valve, flow valve, solenoid valves, hydraulic cylinder, hoses, fittings, and fluid have been checked for related problems.
- The package includes the expected pressure switch and any required fitting, adapter, connector, wiring, or mounting hardware, or those items are ordered separately if needed.
- The hydraulic system has not been modified with non-standard switches, fittings, valves, accumulator hardware, or wiring.
Installation and Service Notes
- Disconnect and secure operator power before servicing pressure switch wiring or hydraulic components.
- Secure the wedge, gate, or moving assembly before opening hydraulic lines or removing pressure components.
- Relieve hydraulic pressure according to the manufacturer's service procedure before removing the pressure switch.
- Keep hydraulic ports, fittings, hose ends, and switch ports clean during service.
- Do not substitute a different pressure range or output style without parts-diagram confirmation.
- Do not bypass the pressure switch or controller input to force the system to run.
- After installation, check for leaks, proper pressure build, proper pump cycling, controller response, accumulator behavior, and smooth wedge or gate movement.
- Verify all required safety devices, access control safety inputs, stop circuits, proximity switches, and controller protections before returning the operator to service.
Professional Advisory
Hydraulic pressure switch replacement should be handled by a qualified gate technician when the repair involves hydraulic pressure, accumulator circuits, pump cycling, high-pressure fittings, controller inputs, hydraulic valves, hose routing, fluid contamination, or unknown prior modifications. Do not bypass hydraulic protections, pressure switches, relief valves, controller protections, proximity switches, limit controls, stop circuits, entrapment protection devices, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
Product Questions & Answers
What is HySecurity MX4112?
HySecurity MX4112 is a hydraulic pressure switch commonly listed as 2200-2500 PSI for select HydraWedge SM50 and HydraSupply XL applications.
What operator uses MX4112?
Nice HySecurity parts documentation lists MX4112 for HydraWedge SM50 hydraulic applications. Current listings also associate MX4112 with HydraSupply XL where the parts diagram confirms fitment.
Is MX4112 the same as the MX3954 pressure gauge?
No. MX4112 is a pressure switch. MX3954 is a 5000 PSI pressure gauge and should not be treated as the same part.
Why do some descriptions show 2200-2500 PSI and others show 2250-2500 PSI?
HySecurity documentation and several listings commonly show 2200-2500 PSI, while some item descriptions may show 2250-2500 PSI. Confirm the original switch marking and current parts diagram before ordering.
Can a bad pressure switch affect pump cycling?
Yes. A failed, miswired, clogged, or incorrect pressure switch can affect pump cycling or controller pressure response. Accumulator condition, relief valve setting, pump output, hydraulic leaks, and wiring should also be checked.
Can I use a generic pressure switch instead of MX4112?
No, not unless the pressure range, port style, fitting, electrical rating, wiring, controller input, and HySecurity parts diagram confirm compatibility.
Should a technician replace this pressure switch?
Yes. A qualified gate technician is recommended because this repair can involve hydraulic pressure, accumulator circuits, high-pressure fittings, controller inputs, and safety-critical hydraulic operator movement.
