Title
 
Polarised Electro-Magnetic Relay
Description
 
Aswitching device invented by Rupert Carpenter of Smitham Bottom Lane, Purley, in the 1920s. It was used to send telex messages and later in telephone exchanges, making it possible to dial long-distance calls from home. Because Carpenter couldn't at first find a British buyer for the relay, he sold it to a German firm who were contracted by Hitler's government to make relays for V2 rockets. Ironically one V2 rocket landed near Carpenter's home, shattering his windows.
