Matrix Switch and Terminal Block
MC3648 is a 4×8 two-wire matrix switch. The 32 two-wire crossing points can connect any combination of
inputs and outputs at the same time. MC3648 is used to connect multiple devices to multiple points on
the device under test at the same time when making tests. You can connect the rows and columns of
multiple matrix switches to form a relatively larger matrix (such as 8×8 and 4×16, the number of crossing
points cannot exceed 160). MC3648 is as shown in the figure below.
