Abstract
An integral multifinger contact with each finger being capable of flexing independently of one another while maximizing the number of independent finger contacts along a given contact line. The method involves the shearing of finger portions and elongating these portions during the shearing operation to provide a positive clearance between adjacent edges of the fingers. One embodiment of the invention being directed to a contact member particularly adapted for a rotary potentiometer while another embodiment has particular use in a linear potentiometer.
