IDEC HE5B Enabling Switches

IDEC HE5B Enabling Switches are 16mm diameter redundant contact pushbutton enabling switches that feature ergonomically-designed OFF-ON-OFF 3-position operation. The IDEC HE5B Enabling Switches provide easy recognition of position 1 → 2 transition, made possible by the snap-action switch. Sufficient load difference is provided for shifting from position 2 → 3. A light force is needed to maintain position 2 so operators can easily use the enabling switch. The switch also does not turn ON when released from position 3 (OFF when pressed) to position 1. The switches provide two contacts for safety and IP65 environmental protection when using the waterproof rubber cover.
