The boot features a nickel-plated hex nut and is constructed from silicone material, which provides excellent performance across a wide temperature range of -40°C to +85°C and offers superior elasticity. The half-toggle design has a height of 11.60 mm (0.457 inches) with a nut width of 17 mm (0.669 inches) across flats, making it compact while maintaining effective sealing. This boot prevents dust, sand, water, and ice from entering the switch mechanism, ensuring reliable operation in harsh environmental conditions. It is available in multiple colors including black, red, green, and white, and is commonly used in industrial control panels and outdoor applications where environmental protection is critical.
