Cleaning:
Tape sealed versions are capable
of withstanding spray wash processes using
alcoholic solvents only, water or other
solvents are not recommended. Care
should be taken to avoid flux from the circuit
board adhering to the switch body. The
switch should be allowed to cool for at least
3 minutes between the end of the solder
process and the beginning of the wash
process. The solvent stage of the cleaning
process is not to exceed 1 minute and the
whole wash process is not to exceed 3
minutes. Ultrasonic cleaning is not
recommended.
