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.

Pushbutton Boots

As the name clearly suggests, a pushbutton switch is actuated using a push, or press, motion. Though this is very different from the actuation motion of a toggle switch, the mounting method is often much the same, making it possible to use a similarly designed silicone boot with a threaded mounting nut. Looking to protect a more complicated pushbutton switch that cannot be sealed with a standard threaded boot? That’s not a problem. Available in both full boot and half boot varieties, APM Hexseal Pushbutton Boots provide excellent sealing protection for pushbutton switches of all styles and sizes.

Rotary Boots

Rotary switches are unique in that they operate with a twisting motion as opposed to a push or press motion. The central shaft of a rotary device must be free to rotate, which can make sealing a rotary device more complicated to accomplish. Since a full-coverage boot does not work for a rotary device, APM Hexseal developed a specialized open boot, molded from silicone to a threaded mounting nut that once correctly mounted, seals around the rotating shaft as well as to the mounting panel. These boots are specifically designed to withstand the friction created by the shaft rotation without restricting the actuation motion.

Circuit Breaker Boots

Circuit breakers perform a very valuable role in all sorts of different control systems, protecting equipment from short circuits and electrical overloads. APM Hexseal’s lever-actuated circuit breaker boots are designed to protect these critical devices, extending breaker life-spans and in turn helping to ensure long-term security of the system as a whole. Created from APM Hexseal’s transparent silicone RUBRGLAS®, which is specially formulated to maintain clarity and prevent yellowing over time, these boots allow for easy device operation and status recognition while maintaining APM Hexseal’s exceptional environmental protection from weather exposure, wash downs, salt water, lubricants, solvents, dust, dirt, grease and any number of other environmental elements that could potentially threaten electrical components. Our two distinct boot styles are Back-of-Panel, secured behind the breaker mounting panel, and Front-of-Panel, mounted to the outside of a panel using a sturdy metal frame. All designs feature a continuous sealing rib around the underside of the flange to ensure a consistent, reliable seal.

Rocker Boots

Unlike traditional toggle, pushbutton and rotary switches, rocker switches do not utilize a round threaded mounting bushing, and therefore a Rocker Boot does not include a threaded mounting nut. In fact, most of APM Hexseal’s Rocker Boots do not include an insert or frame of any kind. The majority of our Rocker Boots are designed to install on the switch prior to the switch installation. Much like our Lever-Actuated Circuit Breaker Boots, APM Hexseal’s Rocker Boots are often molded from transparent silicone RUBRGLAS® which allows for easy viewing of the switch position.
