Philco Band Switch Lever
This knob was used on most Philco radios from 1937 to 1938. Other years may also have used them. This lever is the knob used to switch between AM and Short Wave bands. Rider's manual schematics list this knob as #27-4326. If you are unsure if your radio uses this knob, look under Miscellaneous on the schematic sheets.
Here is a partial list of radios that use this knob:
1937: 11, 116, 610, 611, 623, 630, 640, 641, 643, 650, 651, 655, 660, 670, 675, 2670
1938: 1, 2, 3, 3-3, 116, 610, 620, 623, 630, 643, 690, 2670
These numbers may represent consoles, radio/record players, tombstones, cathedrals, or other table radios. The above numbers would be preceded by the last 2 digits of the year it was made, for example: 610 would be 37-610.
