HE1B
- Three position functionality (OFF-ON-OFF).
- Ideally suited for use as enabling (aka "deadman") switch on teaching pendants.
- Positive action contacts "On" (position 2) to "Off" (position 3) ensure no contact welding (per EN 60947-5-1 / IEC60947-5-1).
- Contacts will not close when released from "Off" (pos. 3) to "Off" (pos. 1) (per IEC60204-1 ; 9.2.5.8).

HE2B
- Three position functionality (OFF-ON-OFF).
- Positive action contacts "On" (position 2) to "Off" (position 3) ensure no contact welding (per EN 60947-5-1 / IEC60947-5-1).
- Contacts will not close when released from "Off" (pos. 3) to "Off" (pos. 1) (per IEC60204-1 ; 9.2.5.8).
- Variety of contact configurations (up to two OFF-ON-OFF and two push monitor and two return monitor).
- Available with or without rubber cover (cover provides IP65 watertight seal).

HE3B
- Fits standard 16mm panel cut-out.
- Three position functionality (OFF-ON-OFF).
- Snap acting contacts from Off - On (position 1 to 2).
- Contacts will not close when released from "Off" (pos. 3) to "Off" (pos. 1) (per IEC60204-1 ; 9.2.5.8).
- Available with or without rubber cover (cover provides IP65 watertight seal).

HE5B
