In their simplest forms, electromechanical switches are designed for “friendly” environments such as clean factory areas, offices, and other surroundings with typical room conditions. However, these devices are often necessary where dirt, dust, metal particles, and corrosive agents are present, in extreme temperatures or in potentially hazardous environments. For these extreme environments, there are switches made from special materials or with protective enclosures that alter the immediate switching area to enable the device to survive and perform.
