Those small SMD switches (aka "dip switch) are really too
small for an operator interface. They are fine for a
set/forget but pretty poor as an operator interface. Also,
they have a very limited number of operation cycles.

Slide switches are not that good for this kind of
application as there is nothing to prevent the operator
from turning on several at the same time. 

What about a multi-position "rocker" switch (with a
relatively large "paddle")? There are a number of small
SP3T or DP3T ones out there. Or, how about one of these
"rock four ways" navigation switch (lower right on page) :
