It can also serve as an emergency main disconnect during an electrical problem, giving the operator a clear way to shut off battery power at the source.\u003c\/p\u003e\u003cp\u003eThis switch is rated for 6-32 VDC marine electrical systems used with alternators and generators. Electrical ratings are 140 amps continuous, 200 amps for 5 minutes intermittent, and 250 amps for 30 seconds starting, with 3\/8\" terminal studs for battery cable connections.\u003c\/p\u003e\u003cp\u003eThe oval switch face measures 3\" x 2-1\/2\", and the removable black actuator key adds a simple layer of control when the boat is stored, docked, or left unattended.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eSingle battery disconnect function helps isolate battery power during storage, service work, or an onboard electrical issue.\u003c\/li\u003e\n\u003cli\u003eSuitable for 6-32 VDC marine electrical systems used with alternators and generators.\u003c\/li\u003e\n\u003cli\u003eRated at 140 amps continuous, 200 amps for 5 minutes intermittent, and 250 amps for 30 seconds starting.\u003c\/li\u003e\n\u003cli\u003eIgnition protected for use in appropriate marine electrical installations.\u003c\/li\u003e\n\u003cli\u003eRed polycarbonate polymer body, black polymer actuator key, and nickel-plated terminals support use in the marine environment.\u003c\/li\u003e\n\u003cli\u003eOval switch face fits a round mounting hole, which helps simplify panel layout on consoles, lockers, bulkheads, and interior gunwale areas.\u003c\/li\u003e\n\u003cli\u003eRemovable actuator key gives the operator a straightforward way to limit casual operation when the boat is not in use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis Perko single battery disconnect switch is offered in more than one mounting configuration so it can fit different helm, locker, console, or bulkhead layouts.\u003c\/p\u003e\u003cp\u003eThe electrical function and core switch design remain part of the same 9621 family. The main difference between these variants is the supplied mounting style and related hardware.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e9621DP: Switch with mounting rings and legs. This configuration supports panel or bulkhead-style installation where the switch needs mounting hardware for the selected surface.\u003c\/li\u003e\n\u003cli\u003e9621DPC: Switch only with cup. This configuration uses the cup mount arrangement, with a cover that hides and protects the switch face when installed.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eFor panel mounting, the listed installation hole size is 2-1\/8\". For cup mounting, the listed installation hole size is 3\", with a cup diameter of 3-1\/2\". The face dimensions are 3\" x 2-1\/2\", so the mounting area should be checked before cutting or replacing an existing switch.\u003c\/p\u003e\u003cp\u003eThe bulkhead mount arrangement allows direct cable access, which can be useful in lockers, storage bulkheads, under-seat locations, and other areas where cable routing matters as much as switch access.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis switch is a practical match for tenders, skiffs, flats boats, inflatables, and small boats with a single battery system. It works well in locations where the operator needs a visible battery shutoff near the console, inside a locker, on a storage bulkhead, or along an interior gunwale wall.\u003c\/p\u003e\u003cp\u003eBefore installation, confirm cable size, overcurrent protection, mounting clearance, and access to the actuator key against the vessel's electrical layout and applicable marine wiring practices.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Switch with Mounting Rings \u0026 Legs","offer_id":52581971329205,"sku":"QBP890691-V1","price":75.39,"currency_code":"USD","in_stock":false},{"title":"Switch Only with Cup","offer_id":52581971361973,"sku":"QBP890691-V2","price":84.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334829_qbp890691.webp?v=1780201913","url":"https:\/\/www.qualityboatparts.com\/products\/qbp890691","provider":"Quality Boat Parts","version":"1.0","type":"link"}
