 Are Relais solid state? 

This article gives no clarification, but I think, it should. Especially as the disambguation side explicitly declares that a solid-state device does not contain relays.
Which I suspect to be wrong. There exist many devices that are called  solid-state an do in fact contain relais. 

Another Question arises about the definition ""moving parts"": There are devices that contain keys and switches and potentiometers, all of them sporting moving (or movable) parts and the devices are regarded solid-state nevertheless. 217.237.149.206  "
