By APM Hexseal 476
APM's HEXSEAL push button boots are molded from a high tear-strength silicone rubber and bonded to a built-in mounting nut. Each encloses the base of the protruding switch bushing and forms a watertight and dust-tight seal against the front panel surface. They are designed to meet the same specifications (MIL‑DTL‑5423) for addressing harsh environmental conditions as APM's toggle switch and other boots. Choice of IP66/68 rated models include transparent, round, flat top, and half-pushbutton designs. All feature a molded in hex mounting-nut, simplifying installation. Armored, and rfi/emi spurious signal suppression models are also available. All are qualified as UL Recognized Components and used extensively in marine, medical, military, aviation, automation, instrumentation and construction equipment — including process and varied industrial plant applications. Made in the USA.
