Intermediate – Almon Brown Strowger invented the first electromechanical switch, known as the Strowger switch or step by step switch. A free PowerPoint PPT presentation (displayed as a Flash slide show) on automatic circuit switch was invented by an undertaker named Almon B. Strowger.

A contact point pair acts as a cross point switch and remains separated or open when not in use. The area approximations for a 64 32x3232 xand a 64 x multiple crossbar switch with pipeline registers Disadvantage crossbar: 1.
Go to Application.
Now if we energize the horizontal bar B, BP will not be latched as the P vertical is energized before B was energized.
