as expected

Exactly as expected, ie. legal devices KY-016. I bought them from multiple sources. This is the first time I've seen them deliver Prime on Revain. If you buy a lot of these, you can buy them cheaper elsewhere. But if you only need 3, this is an easy way to get them fast.

Pros

contact resistance : max. 50 mΩ (initial) ; Insulation resistance: 100 MΩ (min. 250 VDC)

Cons

Socket required
