Side Post Battery Disconnect Switch 12V, Quick Disconnect Battery Cut Off Switch Battery Shut Off Kill Switch for Car (with Long Bolt, 2 Pack)

This switch is for one terminal and one terminal only: the negative side post, with a 3/8 inch hole, on a 12 V system. The supplier rates it at 125 A, which is the current it is meant to sit in the path of while the vehicle is parked and you want the drain stopped.

Negative post only, and the search summary leaves that out

The description is explicit and narrow: battery negative post, 3/8 inch hole only. That restriction decides whether the part is any use to you, because a vehicle carries one negative terminal and this switch will not serve the positive side. The search summary sitting above these words calls it simply a side-post disconnect, with no exclusion attached. We publish the limit as the supplier wrote it, and it is what to hold up against your own battery before anything else.

What 125 A and two positions actually cover

Two electrical figures are given here and both are worth having: the system is DC 12 V, the current rating is 125 A, and the action is a plain On/Off across two positions. What is not given is any test method behind that 125 A, nor a surge or cranking figure, so the number is the supplier's own and is tied to no published standard. If you mean to leave a starter circuit running through it, that difference is worth putting to the seller first.

Key features

• Knob turned by hand: the supplier describes cutting power by twisting the knob loose, and names no tool for doing it.
• Two switch positions: On and Off, as the description has it.
• 125 A rated current: the supplier's figure for what the body of the switch is built to carry.
• Long bolt on the unit: the description specifies a long bolt for reaching the side-post terminal.
• GM side-post pattern: named for GM side post batteries, and for any other battery carrying a 3/8 inch side post terminal.
• Resists rust and corrosion: the supplier's claim for the finish, offered without a salt-spray figure or a material name.
• Isolation for a parked vehicle: sold to stop the draw while a car or a boat sits unused.

Where this listing runs thin

• Negative post only. The search summary above drops that limit, so a buyer after a positive-side isolator has landed on the wrong part.
• The description gives no material for the switch and no colour. Resistance to rust and corrosion is asserted while the metal itself goes unnamed.
• The bolt is called long by the title. No length for it is printed in the description, so reach cannot be checked until it is in your hand.
• Behind that 125 A figure there is no test standard, no surge figure, and no working temperature range.
• The search summary calls this tool-free. Switching it off is a hand action by the supplier's account, but fitting it involves a bolt, and that summary does not separate the two jobs.
• How many switches are supplied is not written into the description; the title says two. Nor is there a fitting sequence, only the single action of twisting the knob to cut power.

If your battery wears side posts and you want the negative leg broken by hand while the vehicle sits, this is the shape of switch that does it; for top posts, or for isolating the positive side, it is the wrong choice.
