A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
On depression of the switch, the webbing uniformly deforms to produce a tactile response. When pressure is removed from the switch, the webbing returns to its neutral position with positive feedback. To make an electronic switch, a carbon or gold pill is placed on the base of the switch center which contacts onto a printed circuit board when ...
Automatic test system switching test equipment allows for high-speed testing of a device or devices in a test situation, where strict sequences and combinations of switching must be observed. By automating the process in this way, the possibility of test errors and inaccuracies is minimized, and only systematic errors would generally be ...
