you can ask about it to JA1IIV Mr. Kubodera by
Postal mail and/or FAX.

A modified band switch (#1) for replacement
TL-922
JA1IIV
Mr. Kubodera has other model, below.
<Shorting type rotary switches>
#1: for Replacement TL-922, 2 - 6
contacts (glass fiber shaft)
You know, original switch has not enough current capacity,
so modified couple of contacts, means increased current capacity.
S7-1 (FRONT SECTION)
Add contact (21M), then you have to wiring among contact (14M) + (21M) + (28M)
to S7-2 contact (28M)
Result: Increased current capacity from 1 contact to 3 contacts
Note: Did not use contact (14M) TL-922 original
S7-2 (REAR SECTION)
Add contacts (1.9M-1) and (1.9M-2), then you have to wiring among contact (1.9M)
+ (1.9M-1) + (1.9M-2) to (VC2-1)
Result: Increased current capacity from 1 contact to 3 contacts
Note: Modified rotator (short bar) dimension
