This document introduces APEM's sealing boots, including material, specification, different types, mounting way and so on.
APEM sealing boots are designed to keep dust, sand, water and, on toggle versions, ice from entering switches. They are supplied with a standard sealing ring or washer and are available in a wide range of colours.
The boots are offered in two material options—neoprene and silicone—with corresponding nut finishes (brass, nickel‑plated or matt black). Detailed tables list temperature ranges, mechanical advantages, and part numbers for full‑toggle, half‑toggle, push‑button and transparent silicone versions across many switch series.
