IDEC HE3B Data Sheet
Enabling Switches
HE3B ø16mm Redundant Contact Switch
Key features:
• 3-position functionality (OFF – ON – OFF) as required for manual robotic control
• Provides a high level of safety based on human behavioral studies that determine
personnel may squeeze OR let go when presented with a panic situation
• Contacts will not re-close when released from Off
• Multiple contacts for enhanced reliability
• Snap acting contacts from position 1 to 2
• Available with or without rubber cover
