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. •
