6 is a safety rating for indoor and outdoor electrical enclosures – also known as submersible enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt) or water (sprays and occasional submersion at a limited depth), and against exterior ice formation.
12 is a safety rating for indoor electrical enclosures that specifies a degree of protection against incidental contact and the entry of solid objects (falling dirt, circulating dust/lint) or water (dripping, light splashing).
13 is a safety rating for indoor electrical enclosures – often called oil-proof or oil-tight – that specifies a degree of protection against incidental contact and against the entry of solid objects (falling dirt, circulating dust), water (drips, light splashes), and oil or noncorrosive coolants (sprays, splashes, seepage).

Illuminated Mushroom-Head Push Buttons

These illuminated, hazardous-location push-button operators light up to indicate they are on or activated. They are more noticeable in crowded or dark control panels and enclosures. These push buttons have large, mushroom-shaped heads that are intuitive and easy to actuate if wearing gloves, making them ideal for use as emergency stop (e-stop) buttons.
