Overview
The Honeywell BA-2RV2-A2 is a MICRO SWITCH BA Series premium large basic snap-action switch designed for precision on/off applications in industrial control systems. This SPDT (Single Pole Double Throw) micro switch features a stainless steel roller lever actuator and delivers accurate, reliable contact switching with enhanced mechanical durability. Built to exacting standards, it is widely used in limit switches, end-of-travel detection, presence/absence sensing, and manual operator interfaces.
Key Features
- SPDT contact configuration with two independent circuits
- Roller lever actuator (stainless steel) for smooth, repeatable actuation
- Snap-action mechanism ensures positive contact engagement
- Rated 20A at 250VAC and 480VAC maximum contact voltage
- Low operating force of 3.5 oz (0.97 N) for reduced actuator fatigue
- Screw terminal connections for secure, permanent wiring
- 20 million cycle life rating at 95% survival rate
- UL, CSA, CE, and ENEC certified for global standards compliance
- Rigid lever design with elongated mounting hole for tool-free positioning
