ABSTRACT:
An inexpensive grounding wrist strap and tether for draining excess electrostatic charge, which may be used once and then disposed. The strap and tether are formed integrally and include a conductive strip having a discrete resistance portion for safety considerations. The discrete resistance portion is formed by making a zig-zag pattern of cuts in the conductive strip, thereby increasing the length of the current path through the discrete resistance portion. Due to the slight resistivity of the conductive strip, the lengthened current path results in a discrete resistance being built into the strip. The cuts may be made in the strip at the same time the strip is fashioned out of a sheet of the conductive material, such as carbon loaded polyethylene.
