A unique, innovative and stylish addition to the 0600 Series. A robust cross polymer enclosure coupled with our most popular buttons. Legend discs are machined from an externally rated bi-colour engraving laminate and then engraved to reveal the base colour, disc legends define the application (custom legends are available). IP66 ingress protection (with the exception of 0661-GB keyswitch - IP65) with pre-moulded knockouts for either cable or conduit glands makes the range suitable for exterior use amongst many other applications.
