On the other hand, a switch in the tropics, in the temperature control system of a
refrigeration unit, may be exposed continuously to cold. The temperate climate of
the central Atlantic Ocean imposes no undue stress on switches, aside from the ...

They also may attack elastomers containing catalysts, plasticizers or fillers that
are fungus-susceptible. Such problems can be prevented by using sealed
switches that have all exposed surfaces made from non-nutrient or fungicidal
materials.

In some cases, the switch terminals are exposed, while in others they are brought
out of the switch as potted leads. The type of actuator seal used depends upon
the intended use of the switch. If it is to be exposed to vacuum intermittently with ...
