APM Hexseal Corp.'s Ultra Flex Toggle Boot 1131/60
To avoid unintentionally tripping a sensitive breaker/switch into the on/off position, we recommend attaching the APM HEXSEAL® 1131/60 inverted bellow toggle switch boot. There are an increasing number of breakers/switches that when covered with an environmental sealing switch cover can trip the breaker switch into the off position due to the mere physics of being covered by the wrong cover. APM uses low durometer rubber in many cases to guard against this tendency. However, there are an increasing number of breaker/switches where this strategy alone is not sufficient, and our “Ultra Flex Series” with a bellow design incorporated therein is very able to combat this problem.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
