The original aerospace transducers and sensors manufactured from the founding of The Bourns Laboratories in Marlan and Rosemary Bourns’ Altadena, California garage all used resistive “elements” along with a moving contact called a “wiper” as their basic sensing device. Most of the Bourns® family of resistive products are direct descendants of this resistive sensing technology. The patriarch of the family is the Trimpot® trimming potentiometer which Marlan Bourns invented while he was home sick for a few days in 1952 and is still today the product for which Bourns is best known.
