A 4x4 nonblocking switch arrangement includes eight 2x2 switches. The switch is nonblocking in that it is characterized by an algorithm that allows the destination of any two input signals to be interchanged by only changing the setting of one particular 2x2 switch. By removing one signal path a nonblocking 3x3 switch is obtained. Both switches have the minimum number of elements. These arrangements can be used as building blocks to construct larger switches and can be dilated to minimize crosstalk.
