In high tolerance environments, designs are &en required which can absorb some of these tolerances. This is especially true with respect to designs requiring solid electrical contact. In many radio and small appli- ance applications, contacts on the unit are connected to a removable power source (battery). With the advent of engineering plastics, these contacts often protrude through a plastic housing or back cover. However, in such a design there is a risk that the plastic will creep or that the screws holding the contacts will loosen; this can result in inter- mittent operation of the unit.
