Description
The 3E0657B-YB-PA is just one of the variants in the range of high impact, externally rated surface mount buttons. The robust two part cross polymer housing incorporates an integral gasket that seals the unit to IP66, coupled with the original green dome, makes the unit an effective and reliable solution for external egress and other outdoor switching applications.
The housings are available in two colour combinations – grey lid with a black base and black base with a highly contrasting yellow lid. Both models are easily identifiable to the user. The base incorporates pre-moulded conduit knockouts (both M16 and M20), these aid installation by ensuring effective cable management.

The discs are gasketed using an open cellular foam, when the switch is tightened to the unit, the cells close to maintain the IP rating. Custom legend discs are available to special order to suit particular applications – please call to discuss your requirements.
