Rocker switches with vertical and right angle terminals must be mounted so that extension of the PC board beyond the top of the switch
housing does not interrupt rocker movement, in turn causing incomplete switching operation.
The MAXIMUM limit of the PC board extension is .051” (1.3mm), as illustrated below.
This precaution does not apply to the double pole switch with right angle terminals due to the extra width of the switch allowing the
rocker to clear the PC board.
