Black boot for lever switch

The Blue Sea 4138-BSS black boot is a protective accessory designed specifically for lever switches. It isolates and protects the switch mechanism from external elements.

This boot's primary function is to protect lever switches from moisture, dust, saltwater spray, and other environmental contaminants. It thereby helps extend the switch's lifespan and reliability in demanding environments, particularly marine ones.

Yes, the black boot for Blue Sea 4138-BSS lever switch is designed to be UV-resistant. This feature is essential to maintain its integrity and color even after prolonged sun exposure, which is common in marine applications.

As its name suggests, the Blue Sea 4138-BSS protection boot is black. This classic color fits easily into most dashboards and control panels.

Absolutely. The Blue Sea 4138-BSS boot is specifically designed for marine applications. Its material is resistant to salt water, UV rays, and dust, making it an ideal choice for protecting lever switches on boats and other watercraft.

The boot acts as a physical barrier. It covers the exposed part of the switch, preventing elements such as water, dust, salt, and debris from reaching the electrical contacts and internal mechanism. This prevents corrosion, short circuits, and premature wear.

This boot is compatible with lever switches (toggle switches) that have a standard mounting thread pitch. It is specifically designed to fit switches with a 15/32 inch diameter thread.

For optimal compatibility, the lever switch must have a mounting thread diameter of 15/32 inches. It is important to verify this dimension on your switch before purchase to ensure a perfect fit.

Compatibility primarily depends on the mounting thread size of the switch. If your lever switch, regardless of brand, has a 15/32 inch thread, this boot should be compatible.

Installation is straightforward:

Remove the existing mounting nut from the switch (if present). Slide the boot over the switch stem. Tighten the hexagonal nut supplied with the boot onto the switch thread, over the base of the boot, until it is firmly secured. Ensure the boot is properly positioned to cover the switch.

Yes, when correctly installed and tightened, the boot is designed to create a watertight seal around the base of the switch and its shaft. This prevents water and dust from entering the switch body.

Yes, thanks to its durable material and waterproof design, the Blue Sea 4138-BSS boot provides excellent protection against saltwater spray. This is a crucial feature for marine applications where exposure to corrosive saltwater is common.

Yes, by protecting the switch from external elements (moisture, dust, salt, UV), the boot significantly reduces the risk of corrosion, oxidation, and mechanical wear. This directly translates to a significant extension of the switch's lifespan and reliability.

The black boot for Blue Sea 4138-BSS lever switch is typically sold individually. Each unit includes a protective boot and a hex nut for installation.

The boot is designed to fit the switch’s shaft and thread. If the illuminated switch has the same thread diameter (15/32 inch) and the light is integrated without interfering with the boot, it should be compatible. It is recommended to check the specific dimensions of your switch.
