Enabling Switches
HE5B ø16mm Redundant Contact Pushbutton Enabling Switch
Key features:
• Ergonomically-designed OFF-ON-OFF 3-position operation
OverviewXW Series E-StopsInterlock SwitchesEnabling SwitchesSafety Control RelaysLight CurtainsAS-Interface Safety at Work
• Easy recognition of position 1 2 transition, made possible by snap action switch
• Sufcient load difference is provided for shifting from position 2 3
• Light force needed to maintain position 2, so that operators can easily use the enabling
switch
• The switch does not turn ON when being released from position 3 (OFF when pressed)
to position 1 (OFF when released) (IEC60204-1, 9.2.5.8)
• Two contacts are provided for safety
• IP65 (using the waterproof rubber cover)
• Mounts in a 16mm (5/8”) round hole
