FEATURES
The BP Series offers a unique means of sealing pushbutton
switches, using a standard 1/4-40 threading bushing, to almost any
thickness panel. Simply install the BP adaptor into a 15/32" dia. or
1/2" dia. panel opening and secure with its hex nut. The switch is
then threaded into the previously mounted adaptor and tightened
into place. A complete and decorative panel seal is the result of the
simple process.
