The detector cells are totally sealed and are never in contact with the water, will not corrode, and are not affected by oil for foreign debris. Johnson Ultima Switch activates at a 2\" fluid level and deactivates at a 3\/4\" fluid level. An eight second delay prevents false starts.\u003c\/p\u003e \u003cp\u003eThe Ultima Switch is rated to handle bilge pumps up to 20A, at 12V or 24V.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eNo moving parts\u003c\/li\u003e \u003cli\u003eTotally sealed solid state electronics and field detectors\u003c\/li\u003e \u003cli\u003eNo mercury\u003c\/li\u003e \u003cli\u003eNo exposed sensors eliminate corrosion possibilities\u003c\/li\u003e \u003cli\u003eUnique 3-way switch disables piezo alarm while keeping warning LED lit\u003c\/li\u003e \u003cli\u003eEnvironmentally sensitive\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003ca href=\"https:\/\/www.wholesalemarine.com\/content\/PDFs\/Johnson-Ultima-Auto-Switch-Manual.pdf\" target=\"_blank\"\u003e\u003cspan style=\"color: #0000ff;\"\u003e\u003cstrong\u003e\u003cimg class=\"__mce_add_custom__\" title=\"pdficon.png\" src=\"https:\/\/cdn11.bigcommerce.com\/s-6rtev5owwo\/product_images\/uploaded_images\/pdficon.png\" alt=\"pdficon.png\" width=\"80\" height=\"77\"\u003e\u003cspan style=\"font-size: small;\"\u003eClick to Download Johnson Ultima Auto Switch Manual\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e \u003ch2 style=\"margin-top: 0; margin-bottom: 10px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3 style=\"margin-top: 5px; margin-bottom: 0; font-size: 12pt;\"\u003eWhat does the Johnson Ultima Automatic Bilge Pump Switch do?\u003c\/h3\u003e \u003cp style=\"margin-top: 0; margin-bottom: 12px;\"\u003eThe Johnson Ultima Automatic Bilge Pump Switch is designed to automatically activate and deactivate a bilge pump based on fluid level.
