Part number 0295490 is a Microswitch specifically engineered for use across an extensive range of professional sprayer systems including SprayTech GPX 85, Airless EPX2255, EPX2155, EP2205, EP2105, and Advantage EPX2255/EPX2155; RentSpray 400; PowrLiner 1800M/2800M and 2850 GB_D_F; and Advantage GPX 85, 500, and 400 models. This precision snap-action switch is a critical component in the electrical control system, responding to mechanical position or pressure changes to open or close circuits. Common applications include pressure switch activation, trigger interlock systems, and safety cutoff mechanisms. When actuated by a plunger, lever, or pressure diaphragm, the microswitch changes state with a characteristic clicking sound, controlling power to the motor, pump, or other electrical components.
The microswitch is manufactured to exact specifications for actuation force, travel distance, and electrical ratings to ensure reliable operation in demanding job site environments. It is typically mounted within the control panel or pressure switch assembly and is subjected to continuous mechanical cycling, vibration, and potential exposure to moisture and dust. The switch's snap-action design provides positive make-and-break contact, minimizing arcing and ensuring consistent performance over thousands of cycles. Proper switch function is essential for automatic pressure control, motor starting and stopping, and safe equipment operation.
Microswitches are subjected to mechanical fatigue, contact wear, and environmental stress. Failure modes include failure to actuate, intermittent contact, welded contacts causing continuous operation, and physical breakage of the actuator. A failed microswitch can cause the motor not to run, run continuously without stopping, or operate erratically. Replacement with genuine 0295490 microswitch restores proper electrical control and ensures reliable operation across this extensive family of professional spray equipment.
| Pressure Control | Responds to pressure changes to start/stop motor |
|---|---|
| Safety Interlock | Prevents operation when safety conditions are not met |
| Position Sensing | Detects mechanical position for control system input |
| Motor Won't Run | No motor operation when pressure demands |
|---|---|
| Continuous Operation | Motor runs constantly and won't shut off |
| No Audible Click | Switch fails to click when actuated |
| Intermittent Operation | Erratic motor behavior due to switch contact issues |
Part number 0295490 is specifically designed for a comprehensive range of professional sprayer systems including SprayTech GPX 85, Airless EPX2255, EPX2155, EP2205, EP2105, and Advantage EPX2255/EPX2155; RentSpray 400; PowrLiner 1800M/2800M and 2850 GB_D_F; and Advantage GPX 85, 500, and 400 models.

The microswitch is part of the electrical control system. When servicing this component, these related parts are often inspected or replaced at the same time.
Often contains or is actuated by the microswitch. Inspect diaphragm and connections.
Electrical connections to the switch. Inspect for damage, corrosion, or loose terminals.
Often controlled by microswitch to handle higher motor currents. Test for proper operation.
