Any unsealed electrical devices mounted to a control panel or piece of electrical equipment can fall victim to the impacts of hostile environmental factors if not properly protected. In this context, “environmental” is a very broad term, encompassing any number of possible factors, including weather conditions like rain, snow or prolonged wind and sun exposure, pressure changes from submersion in fluids or changes in altitude, contaminants such as water, ice, salt, air, dust, dirt, grease, chemicals, and even spilled beverages.

In order to protect against these threats, APM Hexseal designed and patented the very first Sealing Boot in the late 1940s and, in doing so, set the standards for the developing industry to follow.

APM Hexseal’s Sealing Boots and Bushing Seals provide strong protection for both the external and internal workings of a device, ensuring the safety, reliability and overall function of the system as a whole.

APM Hexseal’s Sealing Boots and Bushing Seals are available in a variety of styles and install easily over the vast majority of standard electro-mechanical switches and devices on the market.

MATERIAL SPECIFICATIONS

Toggle Boots

Toggle switches have been widely used across all sorts of industries for a very long time. With their straightforward, back and forth actuation making them easy to operate, toggle switches have continued to be one of the more common styles of switch used today. The long life of the toggle switch has given APM Hexseal the opportunity to develop a variety of designs over the years, incorporating different sealing techniques to cater to a broad range of switch applications and installation environments. The majority of APM Hexseal toggle boots are a single piece design, molded from silicone over a threaded mounting nut. Our designs include fully enclosed toggle boots that cover the entirety of a switch, as well as half boots that leave a portion of the toggle bat exposed. No matter the variation, all APM Hexseal designs include our signature sealing rib that ensures a secure seal with the mounting panel, and are extremely effective toggle switch sealing solutions.
