(f ) If the switch is to be exposed to acceleration, vibration or shock, orient the
switch so that acceleration will not actuate the switch prematurely (see Chapter VI
, A). (g) Minimize changes of temperature and humidity, and avoid exposing the ...

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 ...

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 ...
