Rotary Switch Madness Sale

[Chris Trask]

     I have acquired a large (24" by 24" by 24") box stuffed
with Centralab (Now Electroswitch) ceramic rotary switches,
index assemblies, and switch sections.  The bottom of this box
was 1" deep in nuts, washers, and spacers.  I am offering them
here for sale at prices well below their current market value.
Prices do NOT include shipping and handling.

     Centralab is one of the oldest names in the electronics in-
dustry, so old that they reportedly supplied the stone that the
original ten commandments were written on.  Their ceramic rotary
switches have long been an industry standard for quality.

     Get 'em while they last.


                         INDEX ASSEMBLIES

     All index assemblies are 30-degree spacing, ceramic insu-
lation, and are supplied with the shaft nut, shaft washer, stop
washer, (2) wafer screws, (2) fiber washers, (2) lock washers,
and (2) nuts.  Ceramic spacers are sold separately.
