HE1B Basic Three-position Enabling Switches
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.
