Class Information
Number: 338/114
Name: Electrical resistors > Mechanically variable (e.g., rheostat) > Deformable
Description: Subject matter including a flexible or deformable unitary mass of resistance material together with structure for modifying the shape of the mass, as by increasing the length or reducing the cross sectional area of the mass between terminals, to change the resistance value between the terminals.
