The use of pushbutton boots began in the defence industry, where switches for military equipment required protection from myriad harsh environments, such as deserts, jungles, oceans, and snow/ice. To prevent reliability issues or failure of these switches, APM Hexseal developed our own product line of sealing boots to respond to the military’s growing need for switch protection. All our seals comply with the military design specifications set forth in MIL-DTL-5423: General Specification for Boots, Dust and Moisture Seal (For Toggle and Push-Button Switches, Circuit Breakers, and Rotary-Actuated Parts).
A pushbutton switch is actuated by a push or press motion. Pushbutton boots, as their name suggest, are sealing boots that are used to cover pushbutton switches. Pushbutton boots are typically manufactured from silicone rubber and act as armor for pushbuttons. These boots are used as pushbutton switch covers that protect these devices from harmful external factors such as dirt, water, salt, oil, solvents, humidity, and other particulates.
