Скачать или смотреть Strowger Final Selector

This video shows the testing of a final selector which forms part of the Salford Strowger demonstration project. We are building a small working example of a Strowger telephone exchange. Work is ongoing and this test was to check the final selector. We are using an engineer's butt set (out of shot) to dial two numbers. The first forces the selector to move upwards and the second to rotate to the right. When off-hook, the selector automatically resets itself. This is a 2000 type selector which means that under reset conditions, the wipers pass through the remainder of the switch bank before returning to the start position.
