HE1B-M1

HE1B Enabling Switch 3-position enabling switch to avoid hazards. Ideal for installing in teach pendants and other enabling devices. • Ergonomically-designed OFF-ON-OFF. • Direct opening action mechanism for shifting from position 2 (ON) to position 3 (OFF) (EN 60947-5-1/IEC 60947-5-1, Annex K). • The switch does not turn ON while being released from position 3 (OFF when pressed) to position 1 (OFF when released) (IEC60204-1, 9.2.5.8). • Reliable performance in compact and lightweight package.
