摘要
本文介绍了一种多刀多层多位切换开关,通过阐述此开关的实践应用,提出了一种解决目前中波发射台所用双刀双位开关不能在三套以上天馈系统和一套备份天馈系统之间进行切换的问题解决思路。
This paper introduces a multi-pole,multi-layer,and multi-position switch.By explaining practical application of this switch,a solution is proposed to solve the problem that commonly used two-pole and two-position switch can not switch between more than three sets of antenna feeder system and one set of backup antenna feeder system.
