Contender® Series factory sealed tumbler switches prevent ignition of hazardous atmospheres by containing any arcing within a factory sealed enclosure. They are fitted to work in settings that currently use competitor’s back bodies and covers, allowing you to benefit from Appleton features and reliability without upgrading the entire electrical infrastructure. Handles can be padlocked in either the on or off position.
