Crouse-Hinds AFU:4346A Spring, For Use With AFU254/AFUX 600 VAC Explosionproof Mine Signal Switch

AFU mine signal switches from Eaton's Crouse-Hinds Division are used for signaling circuits or for manual remote control of magnetic motor starters in non-hazardous areas of mines or process industry facilities where a rugged enclosure is needed for protection from falling ore and other material or dripping water. AFU switches are mounted on walls or in shaft ways and actuated by pulling the line or cable attached to the loop at the bottom of the unit.
