designed or can be modified to meet the varied requirements as specified
in Mil-Std-810 or Mil-Std-202. These
requirements include, among others, the Environmental Test requirements
such as Salt Spray, Temperature Cycling, Humidity, Sand and Dust, Moisture
Resistance; and Physical Characteristic Tests such as Vibration, Shock,
Acceleration; Electrical Characteristic Tests such as Dielectric,
Insulation Resistance, Contact Resistance as also outlined.
When forwarding to the factory an application data sheet or other
request for quotation, please detail specifically all of the specification
levels to which the switch must be qualified.
