HE3B ø16mm Rectangular Three-position Enabling Switches
Rectangular operator part with ø16 mm mounting for easy installation.
2-contact 3-position enabling switches ideal for installing in small teach pendants.
• Ergonomically-designed OFF-ON-OFF operation.
• Easy recognition of position 1 to 2 transition is made possible by
a snap action switch.
• Sufficient difference in operating force is provided for shifting
from position 2 to position 3.
• Low pressure is required to maintain in position 2 allowing for
longtime operation.
• Reliable operation is assured even when the edge of the opera-
tor button is pressed.
• The switch does not turn ON while being released from position
3 (OFF) to position 1 (OFF) (IEC60204-1, 9.2.5.8).
• Two contacts are provided in a 3-position enabling switch so
that even one contact fails due to welding or short-circuit, the
other contact can disable machine operation.
• The waterproof rubber boot provides IP65 protection.
