Titan part 9850938 is a boot switch / circuit breaker assembly used on compatible SprayTech airless sprayers. This component combines the ON/OFF switch with a protective circuit breaker that trips when current exceeds safe limits, preventing damage to the motor and electrical system. Replacing a faulty boot switch restores reliable starting and overload protection.

The Titan 9850938 Boot Switch / Circuit Breaker is a combined power switch and overload protection device used on SprayTech Airless EPX2305 and EPX2205 sprayers. The rubber boot protects the switch from moisture and debris, while the internal circuit breaker trips automatically when amperage exceeds safe levels, preventing motor or wiring damage.
Over time, the switch contacts can wear, the breaker can become weak or fail to trip, or the rubber boot may crack. Symptoms include the sprayer not turning on, tripping immediately or frequently under normal load, or intermittent power loss. Replacing the assembly restores reliable starting and proper electrical protection.

Electrical issues may involve more than the switch/breaker. Inspect these components when troubleshooting.
Damaged or shorted cord can cause breaker trips – inspect for cuts or melted insulation.
A failing motor or shorted control board may repeatedly trip the breaker – test before replacing switch.
Loose or corroded terminals can cause intermittent power and mimic switch failure.
