A potentiometer comprises a support member having first and second support regions and an intermediate region located therebetween, a resistive member supported on the support member at the first support region thereof and having a longitudinal dimension extending transversely of a line from the first support region to the second support region, and a resilient contact member secured to the support member at the second support region and extending over the intermediate region and terminating superjacent the resistive member. The contact member is flexible both about axes which extend parallel to the transverse line and about axes which extend transversely of the transverse line, whereby application of pressure to the contact member at a location over the intermediate region causes the contact member to engage the resistive member and movement of the point of application of pressure perpendicular to the transverse line causes the point of engagement of the resistive member by the contact member to move along the longitudinal dimension of the resistive member.
