Description
Battery Charger Switch Kit – 6 Position Replacement Switch with Panel Nut Mount fits Various Battery Chargers
This rugged rotary switch is a favorite for replacing obsolete charge rate switches in various battery chargers. It can be used as a cost-effective retrofit to replace more expensive OEM switches in many brands. Designed to be easy to install through a 7/16″ stem-mounting hole and retained with a panel nut. The wire terminals use industry-standard solderless .250″ push-on connectors.
This switch has an OFF position and 5 power positions that are spaced in 60° increments across a 300° arc. When oriented with the OFF position at 12 o’clock, the 5 contact positions are at 2, 4, 6, 8 and 10 o’clock.
The switch may be rotated to accommodate chargers that have the OFF position labeled at other clock positions on the charger cabinet. For example, if OFF is located at 8 o’clock on the charger, this switch may be installed to align with OFF at 8 o’clock and the power positions would then be at 10, 12, 2, 4, and 6 o’clock.
NOTE: No specialty tools are required. Drilling of the cabinet may be necessary, using 1/4″ and 7/16″ drill bits. Drilling instructions and template are provided in the instructions. This switch is a good choice as a non-OEM replacement for obsolete switches in older battery chargers. Instructions are included to assist in determining proper wiring connections for these retrofit applications. The instructions require the use of a multimeter.
NOTE: Effective May 2026, this switch is shipping with a friction-fit push-on knob with a spring-steel insert. It has the same appearance as the set-screw knob, but it is easier to install and will not work loose over time. The part number for the new knob is .
