Battery Disconnect Switch, DC 12-48 V Battery Power Isolator Cut Off Master Switch Kit for Vehicles Motorcycles and More (100A, 1 Pack)

This isolator mounts through a 22 mm hole in whatever panel you drill, which means you choose where the cut-off lives — beside the driver's seat, at the helm, on the mower's flank — and a switch you positioned yourself is one your hand learns to find without looking. The housing measures 1.7 by 1.45 by 2.57 inches (roughly 43 by 37 by 65 mm) and the switch gives two positions, on and off.

Two voltage stories, and which one we print

The store title says 12-48 V. The supplier's body text says something different: compatibility with DC 6 - 60 V systems, and a rating of up to 100 A that applies at DC 12 V specifically. Those body figures are what we publish, qualifier intact; the title's narrower window is a conflict the source never resolves, so it stays flagged rather than repeated.

What arrives besides the switch

Each switch ships with two copper wire lugs, sized by the supplier for 11-5 AWG cable — its ordering of the range, kept as printed — and two terminal covers to go over the studs once cabled. The contacts and terminal stud are copper, the housing ABS plastic, and the purpose the supplier declares is the usual storage case: no draw while the machine sits, safe disconnection when you work.

Key features

• Mounts where you decide: a drilled panel up to 0.787 in (20 mm) thick takes the switch.
• Lugs and covers included: two of each, so heavy cable can land on the studs and be shrouded the same day.
• Copper contact and stud: both named copper by the supplier, inside the ABS body.
• Wide machine list: nine applications named, from cars and motorcycles through electric bicycles and lawn mowers to boats and solar cells.
• Storage-first purpose: the battery stops feeding anything the moment the switch opens.

Specifications

• Body, LxWxH: 1.7 x 1.45 x 2.57 in (approx. 43 x 37 x 65 mm)
• Panel cut-out: 0.866 in (22 mm) — conversion checks exactly
• Panel thickness, up to: 0.787 in (20 mm)
• Housing shell: ABS plastic
• Contact metal: copper
• Current rating: up to 100 A at DC 12 V
• System window: DC 6 - 60 V
• Kit extras: 2 copper lugs (11-5 AWG), 2 terminal covers

Numbers in tension

• Two voltage windows compete across this listing — 12-48 V in the title, 6 - 60 V in the description. We print the description's and decline to arbitrate between them.
• The 100 A rating is qualified: at DC 12 V. Any unqualified "handles 100A" you meet elsewhere on this listing overstates the source.
• The stud is printed as "M6 x 2". A 2 mm pitch is not a standard M6 thread; it may instead mean two M6 studs, but the source never settles it, so the line stands as printed and unguessed.
• No installation or safety text accompanies a switch rated to pass 100 A; have the wiring judged by someone qualified.
• Weight is unstated, and the metric housing figures above are our arithmetic, not the supplier's.

This one asks for a drilled panel rather than a clamp on the post, and repays the effort with a mounting spot of your choosing and two copper lugs already in the box.
