HE1G-L Grip Style Three-position Enabling Switches
The distinctive tactile feedback makes it easy to know the current position of the switch.
Light operating force ideal for long-hour operation
• Ergonomically-designed OFF-ON-OFF operation.
• The switch does not turn ON when being released from position 3
(OFF when pressed) to position 1 (OFF when released) (IEC 60204-
1, 9.2.5.8).
• Two contacts areprovided so that even if one contac fails due to
welding or short-circuit, the other contact can disable machine
operation.
• Monitor switch is direct opening action.
• The distinctive tactile feedback when shifting to position 2 (enabling
position) makes it easier to know where the enabling switch is
currently positioned—position 1 (OFF), 2 (ON), or 3 (OFF).
• Lighter operating force on position 2 assures more comfortable,
stress-free operation when operating long hours.
• Emergency stop switch and momentary pushbutton versions are
available.
• Screw terminal and internal connector models can be selected.
• IP66 degree of protection (HE1G-L21SM)
