Does anyone know of a source of the AC line rocker switch used on the
Collins 30L-1? It is S2 on the schematic, DPST Collins part #
266-6020-00. Any idea who manufactured it and their part number?

Hi,

I have a 1973 edition 30L-1 manual, and Collins included vendor
ID numbers next to many items in the Group Assembly parts list.
Switch S2 was made by Mc Gill Mfg Co.
907 N. Lafayette St.
Valparaiso, IN 46383

Vendor P/N C811-113010109

Please let us know if they are still in business.
That "C" in the part number may mean it was special-ordered
by Collins.
