Improved bobbin potentiometer, characterized in that it is constituted by a cylindrical outer shell, a cap of insulating material that houses the cylindrical fixed coil of the potentiometer and the externally operable rotary contactor. The outer envelope has projections directed in the direction of the generatrices of the envelope which, like the terminals of the coil, are especially suitable for adaptation to printed circuits.
