パイロットスイッチをパナソニックのコスモワイド21に交換

We replaced an old full-color light switch that we had been using for nearly 25 years with a Panasonic Cosmo Wide 21. This time we replaced a single switch with a built-in indicator light. After replacing it, it became easier to operate the light buttons and operation was improved and the look became more luxurious, making the house feel like it had been upgraded slightly. This is a cheap, DIY way to replace it yourself without spending a lot of money. We recommend this video to anyone who wants to replace it as cheaply as possible. The work is easy, but you will need an electrical work qualification. ★Product information.
