Overview
The Fuji Electric AH25-J2B selector switch is a proven pilot control device engineered for industrial machinery and electrical panel installations. This 2-position keyed selector delivers maintained-contact switching at 600V and 10A capacity, making it suitable for operator-controlled circuit transitions in machine tools, automation systems, and process equipment.
Key Features
- 2-position maintained-contact design for reliable mode switching
- 600V/10A electrical rating for AC control circuits
- Keyed selector mechanism with detent positions
- ø25 series form factor for standard panel cutouts
- Non-illuminated, compact design
- Industrial-grade construction for harsh environments
Technical Specifications
The AH25-J2B operates as a mechanical selector switch with fixed contact configuration. Typical applications require secure panel mounting with appropriate through-hole or threaded adapter. Operating temperature range is standard industrial (-20°C to +70°C). Weight is approximately 0.25 lbs. The switch accepts standard keyed knob actuators and maintains electrical continuity across selected positions without spring return.
Typical Applications
- Machine tool mode selection (manual/automatic/test)
- Industrial control panel operation
- Equipment startup/shutdown sequencing
- Pump or motor circuit selection
- Production line mode switching
- Maintenance circuit isolation
