1/ MS25253-4 is canceled, use MS25253-1.
2/ Application information
Power circuits Those electrical loads where the voltage and current exceed the minimum arcing
conditions of the contact material. As a general rule, application loads in excess of 8 volts, 0.5 amperes
are considered power circuits.
Electronic logic circuits Those electrical loads in which the applied voltage is less than the arcing
voltage and greater than the non-arcing application loads in excess of 0.5 volts are considered logic
level circuits.
Low level circuits - Those electrical loads in which the applied voltage is less than the softening
voltage of the contact material. As a general rule, application loads less than .08 volts are considered
low level circuits.
3/ MS25253-8 through 13 have two levels of capabilities. However, switches previously tested or used
above 10 milliamperes resistive at 6 V dc max or peak ac are not recommended for use in electronic
logic or low level application.
