(aka P&B) was the leading manufacturer of electronic relays in the United States; devices that control the flow of electric current. Vital components in a wide range of products, relays are found in small appliances, automobiles, furnaces and air conditioners, and vending machines. P&B also designs and markets timers, connectors, circuit breakers, input/output modules, and other mechanisms necessary in the transmission of electric power. A subsidiary of the German conglomerate Siemens AG since 1986, P&B focused on developing new products as well as consolidating and automating its production lines in the 1990s, in order to compete more effectively with Japanese relay manufacturers. P&B’s history may be traced to 1932 (incorporated in 1933), when Elbert E. Potter and Richard M. Brumfield established a small manufacturing business in their hometown of Princeton, in southwestern Indiana. At the time, the two young men were employed at the local Hansen Manufacturing Company, which produced small motors for clocks. There, Potter was a toolmaker, and Brumfield, who had studied engineering at Purdue University, worked in the design and drafting department and also operated a die cast machine. During 1932, however, both men were often out of work, as the company was forced to lay off large numbers of its employees in order to withstand the effects of the Great Depression. During these periods of unemployment, Potter and Brumfield decided to try developing a business of their own. P&B’s parent company, AMF, had also expanded during the 1960s and 1970s. However, its rapid growth rate through acquisition had engendered several problems. In the early 1980s, AMF’s debt load was high, its energy division, which included interests in petroleum drilling and exploration, was experiencing heavy losses, and its stock prices were plummeting. Siemens AG has owned the company since 1986.Your shipment will arrive via USPS Priority Mail (1-4 business days) or USPS Ground Advantage (2-5 business days), after the 2-3 day processing time (upon paid purchase)ASK ABOUT COMBINE-SHIPPING - CAN SELL IN BULK!Shipment(s) sent out of Lemon Grove, California, USAWill be packed very well - READ OUR FEEDBACK!No Returns ***AN INVOICE WILL BE SENT AFTER PURCHASE, WHICH MAY REFLECT A MORE ACCURATE POSTAGE RATE FOR THIS ITEM - DON'T PASS THIS UP YET!
