AB Switches


These things are extremely important in life, as any astute person recognizes (I include all my dear readers in that sweeping statement).

In early computer-controlled telephone offices, the computer was literally duplicated. While Fred was busily attending to people dialing numbers, running the office and all, Barney was looking over his shoulder waiting for him to make the smallest mistake and then seize control. Both guys thought they were pretty clever. Neither realized that I could walk up to their control panel and flip the AB switch that told them which one I wanted to run the show. 

When I go stereo shopping for that perfect subwoofer that will vibrate the floorboards but not actually lift them, I listen to some music at, well, floorboard floating levels. Which to buy? Switch back and forth between the two top contenders...using an AB switch. 

To every curmudgeon's endless disappointment, these things don't work on wives.
