 MECHANICAL CONTROL Definition
We define MECHANICAL CONTROL |
MECHANICAL CONTROL - A dial or knob whose physical setting directly affects some measurement. For example, the power button in early PCs was a mechanical control, as were the huge, hand-controlled electrical switches in old horror movies and light switches on your wall. By pushing the power button you used to physically make an electrical contact so that power could flow to your PC. Nowadays most power buttons only send signals to the motherboard and are no longer mechanical controls. |
