Built with tin‑plated copper terminals and a PA66 housing, it provides corrosion resistance and high current capacity while allowing a removable knob to lock out unauthorized use. Install hardware and a simple guide are included so you can wire it on the negative or positive side depending on your setup.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this switch protect my battery when a vehicle is parked?\u003c\/h3\u003e\n\u003cp\u003eFlipping the MOTOFLEX disconnect physically breaks the circuit between the battery and vehicle accessories, halting all parasitic current draw.

It suits anyone who wants to stop battery drain during storage, add a theft deterrent, or install a heavy‑duty mechanical isolation switch where ruggedness and corrosion resistance matter. Note: this is a manual power cutoff; devices that keep memory when power is removed (such as radios) will lose settings when the switch is opened.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this switch be used on both positive and negative battery cables?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it can be installed on either the negative or positive side; negative is recommended when possible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will electronics lose memory when I turn the switch off?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, devices that require constant power to retain settings will lose memory when the battery is disconnected.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MOTOFLEX","offers":[{"title":"Default Title","offer_id":48087463067806,"sku":"B0F7G6LD4W","price":40.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/motoflex-front-mounted-switch.jpg?v=1785924403","url":"https:\/\/northtrailauto.ca\/products\/motoflex-battery-disconnect-switch-12v-48v-300a-side-post-red-removable-knob-corrosion-resistant","provider":"North Trail Auto","version":"1.0","type":"link"}
