This slide will answer some of the most common questions associated with preventing premature switch failure due to exposure to harsh environmental conditions. Question 1 is “What are the most common contaminants that lead to premature switch failure?” The answer is that choosing the right electromechanical switch for harsh environments involves many considerations such as Extreme temperatures, Water, Chemicals, Dust, Oil, and Other contaminants. Question 2 is “In which other environments does exposure to these contaminants often occur?” The answer is that the three most common environments where switches are likely to be exposed to harsh conditions and contaminants are automotive, transportation, and heavy equipment applications. Industrial control panels and medical equipment are also exposed to harsh conditions but each of these cases has unique environmental factors that need to be considered. Question 3 is “When is the redundancy of an IP-Rated switch with a splash proof boot recommended?” The answer is that an IP-Rated device with a splash proof boot is recommended when safety is a factor in any harsh environment.  Consider the possibility of the switch housing becoming compromised and breaking the housing’s seal. Having a protective boot on the device would provide a second but necessary barrier of defense against contaminants.
