3 position funtionality (OFF – ON –OFF) as required for manual robotic control
Ideally suited for use as enabling (aka “deadman”) switch on teach pendants
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
Snap acting contacts from Off‡On (1‡ 2)
Positive action contacts from On‡Off (2‡ 3) ensure no contact welding (per
EN60947-5-1 / IEC60947-5-1)
Contacts will not re-close when released from Off‡On (3‡1) (per IEC60204-1;
9.2.5.8)
Multiple contacts for enhanced reliability
Monitoring contacts in addition to main load contacts
Available with or without rubber cover (cover provides IP65 watertight seal)
