Potter & Brumfield Parts
Potter & Brumfield was founded in Princeton, Indiana, in 1933 and by the mid-1950s was the largest American relay maker. AMF owned it from 1954, Siemens bought it in 1986, and Tyco took it over with Siemens Electromechanical Components in 1999, so P&B relays are now a TE Connectivity brand.
The Potter & Brumfield parts here are relays: R10 and R50 series relays, 35 A power relays and 3PDT relays with 11-pin octal plug-in bases.
When you replace a relay, match the coil voltage and whether the coil is AC or DC, then the contact form (SPDT, 3PDT, 4PDT) and the contact rating. A plug-in octal relay also has to match its socket pin count.
