The Stellar Industries 70491 Pressure Switch is a Nason CF-series high-pressure overload switch designed for compatible Stellar 4421 service cranes. Identified as CF-11C-2300R/WD, it has a factory-set rising actuation point of 2,300 PSI.
This switch monitors crane hydraulic pressure and provides an electrical signal when pressure reaches the preset overload threshold. Its sealed piston sensor and Deutsch electrical connector provide dependable operation in demanding mobile equipment environments.
What This Part Is Used For
The Stellar 70491 switch supports the overload-protection system on compatible Stellar 4421 cranes. When hydraulic pressure rises to 2,300 PSI, the switch changes electrical state so the crane’s control system can identify an overload condition and restrict designated functions.
Common Reasons For Replacement
Overload system activates at the wrong pressure
Crane displays a false overload condition
Overload protection fails to activate
Hydraulic functions remain restricted without an overload
Switch operates intermittently
Deutsch connector or wiring is damaged
Hydraulic fluid leaks around the pressure connection
Internal piston sensor is worn or contaminated
Switch damaged by excessive pressure or vibration
