What is the maximum number of switches in
a gang switch assembly ?
If
the switches are not inter-locked type (independent to
each other), there is almost no limitation on the maximum
number of switches in a gang switch assembly. However,
if the switches are inter-locked (dependent to each other),
we suggest customer limit the number of switches below
15pcs.

What
is the soldering and cleaning conditions ?
The
top of the housing cover and the plunger area is not sealed
against flux. So the soldering process must be controlled
so as not to have flux migrate into the switch through
the top of the housing. Good venting is required. If cleaning
is required, pay attention to keep the switch in an up-right
position so as not to let the cleaning solution enter
the switch via the unsealed area.
