NSTALLATION
:
The terminal base is installed manually, or with automatic equipment, on the PC board. It is then wave soldered along
with other board components. The base is compatible with fluorinated, chlorinated and aqueous cleaning methods to
remove flux. When the board and its components have been cleaned and dried, the
Switch
pushbutton switch body, which has not been exposed to the contamination associat-
body
ed with these operations, is snapped positively onto the terminal base, where it is

securely retained.
