INCREASING THE HEFT?

摘要

I am interested to know if the handset for your industrial-strengthened phone has some additional "ballast," "Heft: It's the New Quality Attribute,". Many years ago I opened up a non-working phone's handset to find a slab of lead. At the time, I figured it was there to increase the heft, and therefore the perceived quality, but now I also wonder if it improved the reliability of the hook switch, allowing a stiffer spring on the switch.
