Design Recommendations
-
“P”
leads are recommended f
or a
pplica
tions where shear resistance is of importance
-
When a precise alignment between a
pplica
tion button and the switch is requested,
version with pegs are the right choice to limit the possible f
loating of the switch
during soldera
bility
.
