RARE 1928 LEACH BREAK - IN - RELAY MODEL 18 (COMBINED ANTENNA And POWER SWITCHING)




Item History & Price

Information:
Reference Number: Avaluer:43882167Type: Relay
Brand: LeachUPC: Does not apply
Original Description:
Offered is a Leach Model 18 Type S1 Break-in Relay made by the Leach Relay Co. of San Francisco. The company moved to Los Angeles in 1929, and I believe this model was introduced in 1928.

It's purpose was to make it easier for an operator at the receiving end of a transmission to interrupt the sender in case of interference or other problems, to "break-in" to the transmission.

For a detailed description, there is a scanned version of the catalog which describes this devic...e and its function. I can't provide a link due to eBay's rules, but if you Google "leach break-in relay", you can find it at a telegraph collector's website. It's the one with a ham call in the URL.
The relay operates on 6 volts DC, and it's original cost was $23.00, so it was an expensive item at the time. All contacts are solid silver, the big ones are 5/8" in diameter. The base measures about 4 by 5 inches and it weighs about 1.5 pounds.  The coils are OK and it's complete and all original, as far as I know.
It is offered as I found it, and it needs a good cleaning to look its best.
These don't show up very often.

Thank you for looking!
