MK Electric Masterseal Plus IP66 Switches
The MK Masterseal Plus IP66 Switches range delivers rugged, weatherproof switching solutions ideal for gardens, driveways, workshops and commercial exteriors where dust and moisture are a concern. Each switch is housed in a robust IP66-rated polycarbonate enclosure, providing total ingress protection against dust and high-pressure water jets from any direction. With options including single-pole 1-way, 2-way, 2-gang and push-to-make/push-to-break press switches, installers can specify the right control for lighting or equipment circuits. The range incorporates large, easy-to-operate rockers and clearly marked terminals designed for fast, secure wiring even when working with gloves in challenging conditions. The weatherproof enclosures are built from UV-resistant, impact-tough materials that won’t discolour, crack or fade over time, ensuring reliable operation in both domestic and commercial settings. Backed by MK’s industry-leading 20-year product guarantee, Masterseal Plus IP66 switches give specifiers and installers confidence in long-lasting performance where traditional wiring devices might fail.
