DESCRIPTION

The HE2B-M211PY is a multi-contact 3-position enabling switch designed for installation in large teach pendants, featuring ergonomic OFF-ON-OFF operation with snap-action transition from position 1 to 2 and sufficient operating force differentiation for position 2 to 3 shifting. The switch incorporates 2 main contacts (NO1–C1, NO2–C2), 1 button return monitor switch contact (11–12), and 1 button depress monitor switch contact (31–32), with a waterproof rubber boot providing IP65 protection and direct opening action mechanism. Electrical ratings include a rated insulation voltage of 250V, rated thermal current of 3A, and contact ratings ranging from 0.1A to 2A depending on load type and voltage (30V, 125V, or 250V AC/DC). The switch operates reliably across -10°C to +60°C (with NBR/PVC polyblend rubber boot), withstands 1,200 operations per hour, and achieves 1,000,000 mechanical cycles (position 1?2?1) and 100,000 electrical cycles minimum. This design ensures safe machine operation in dual-switch pendant configurations by preventing unintended enabling when one switch is in the OFF position, making it ideal for industrial automation and robotics applications requiring redundant safety control.
