[Boatanchors] WTD: Intercom Switches for Battleship

[Rod Hogg]

Jay,
You might have luck getting a switch from a shop that sold and serviced the
Talk-A-Phone intercoms.  The switch you describe sounds about like the one
they used in their intercoms and remotes.  I am sure they have long since
discontinued the product but am sure there are service shops that have parts
around. Or get one at second hand store.

Model K-LC-2 master and remote and the 5 station unit K-ML-5 have same
switch.  I got a nice set at thrift shop for $1.00 a while back.

Subject: [Boatanchors] WTD: Intercom Switches for Battleship

The volenteers on Battleship Massachusetts at BattleShip Cove in Fall
River are trying to restore to working condition the xxxx  intercom
system. Each station has a speaker which doubles as a microphone, an audio
power amplifier, and the necessary switching.

The immediate problem is that about 6 of the Talk-Listen switches have
been damaged beyond repair, likely by excessive force. They do not appear
to be available, other by special order from the maker, which is well
beyond the resources available.

The switches are a bit odd: They are two position rotary switches, but
momentary contact. One of the two positions is spring loaded, so if the
knob is released from the TALK , the switch returns home to the LISTEN.
The switch has two wafers, and each wafer is 3-pole; 2-position.

The switch was made by Centralab, P/N 2BFX6977.

Does anyone have a catalog or data sheet that lists this number? Ideally,
I'd like the part numbers for the actuator part and the phenolic wafers so
the needed switched could be assembled from bits scavenged from other
switches.

Also, does anyone know of a source of such switches or the constituent
parts?

Thanks,
-John
