Overview
The Honeywell BA-2RV-A4 SPDT micro switch is an industrial-grade snap-action switch designed for precision on/off control in automation, process control, and machinery applications. Part of Honeywell’s MICRO SWITCHâ„¢ BA series, this switch combines reliable electrical performance with mechanical simplicity, making it ideal for limit switches, safety circuits, and control logic applications where repeatability is critical.
Key Features
- Single-pole double-throw (SPDT) contact configuration for versatile switching logic
- Rigid straight lever actuator for consistent, repeatable operation across millions of cycles
- Snap-action mechanism with low operating force and sensitive differential travel
- Silver-plated contacts for reliable electrical performance
- Phenolic housing rated for general-purpose industrial environments
- Screw terminal connections for secure, tool-free wiring
- Elongated mounting holes for flexible, accurate installation
