ASW-A1201 275A ON-OFF Battery Switch

DAIERTEK ASW-A1201 is a rotary battery disconnect switch specified for 275 A working current and 1,250 A cranking current at 12 V DC, with a 12-48 V DC operating range. The body measures 68 x 68 x 75 mm, with 2 x 5/16 in terminal studs and ON-OFF operation. The two-terminal arrangement connects a single battery feed to its outgoing circuit; OFF isolates that circuit. A removable red knob and rear terminal cover provide access for operation and cable installation. Four mounting screws are supplied. Current ratings are reduced by 50% at 24 V DC. The product is supplied for automotive aftermarket distributors and vehicle equipment assembly programs.
