Please Identify Weird Component. Answered
The metal disk is a component, physically broken in an RCA f32450 tv. The blue capacitor was sent by sears as a replacement. Yeah, I don't think that's the right part, guys.
The component was near the built in fuse, has very low resistance ~ 3 ohms from 1 face to the other, and used to have it's leads soldered directly to it's surface where the diagonal mark is.
My theory is that it is designed to break if the tv is jarred. Sort of a mechanical impact sensor.
Does anyone else know with any certainty?
