APEM Toggle Switch Sealing Boots

One of the main reasons switches fail is because they have not been sealed correctly when initially installed. Using sealing boots or hoods provides extra protection and can prolong the life of the components they are used with. Sealing boots prevent the ingress of dust, sand, and moisture from penetrating the switch and causing potential damage or failure.

APEM’s range of sealing boots/hoods are simple and for easy to use. Robustly designed the one-piece construction is made from a moulded toggle cover bonded to a built-in mounting nut. Easy to fit, APEM’s toggle switch boots are used in place of the original mounting nut. This encloses the base of the switch bushing forming a tight seal against the front of the panel face.

The APEM full-toggle (standard) range of sealing boots are made from a choice of tough materials. Either high-temperature Silicone or mechanically resistant Neoprene. Both types of sealing hoods have nickel-plated brass fixing hex nuts with a plain or knurled edge.
