Guest Diesel Power Battery Heavy-Duty Switches

Guest 2300A, 2303A, and 2304A heavy duty diesel battery switches are for use where high amperage is required, such as diesel engine starting applications. Alternator field circuit disconnect (AFD) interrupts the alternator field when switch is turned to "off" position, preventing electric surges in the armature circuit that may burn out alternator diodes. Heavy-duty copper contacts help to ensure positive circuit control, and the rugged polycarbonate case with built-in skirt protects the electrical connections. Panel or flush mount. All diesel switches measure 5-1/2" square and 3-1/2" high.

Cable lug size: 5/8"
