White 6-32V Marine Battery Isolator Switch IP66 Battery Disconnect Switch for Yacht RV Van

The MT065-W is the white-finish version of our multi-purpose battery isolator, built for vehicles and vessels where the panel is light-coloured and a black switch would stand out. Underneath the housing it is the same high-current design: a 6V to 32V operating range, a 105 mm body, and copper conductor parts sized for heavy loads rather than light accessory duty.
The switch is intended for owners who need one reliable cut-off across very different machines — construction equipment, yachts, motorhomes and vans all use the same part number. Turning it to OFF breaks the battery loop completely, which stops the slow drain from clocks, controllers and standby electronics and removes any live feed before maintenance work begins.
A sealed ABS housing with an IP66 rating keeps spray, dust and washdown away from the contacts, so the unit can live on an open machine deck or inside an engine bay without extra protection. The white finish also makes the switch easy to spot against dark panelling when you need to isolate power in a hurry.

• White finish — blends into light panels and stays visible against dark ones.
• Wide 6–32V operating range — one part number covers 12V and 24V machines without a second SKU.
• Heavy-load contact assembly — copper parts carry high current with less heat at the terminals.
• IP66 sealed housing — resistant to dust ingress and water jets from any direction.
• Multi-purpose fitment — construction machinery, yachts, RVs and vans from a single stock item.
• Full isolation at OFF — stops parasitic drain and leaves the circuit dead for service work.
• Straightforward mounting — surface-mount base with a 105 mm body that suits existing cut-outs.

• Disconnect the battery negative lead first and verify the circuit is dead before starting.
• Choose a flat surface with enough clearance behind the panel for the cable lugs.
• Mark and drill the fixing points, then test-fit the base before final tightening.
• Terminate battery and load cables with ring lugs and torque both stud nuts firmly.
• Cycle the dial through its positions once, then confirm continuity at ON and an open circuit at OFF.

• Construction machinery — excavators, loaders and compact plant that sit idle between jobs.
• Yachts and boats — master isolation on deck panels and in engine compartments.
• RVs and motorhomes — winter storage isolation for the house and chassis batteries.
• Vans and light commercial — accessory and auxiliary battery isolation for conversion builds.
