That looks like a badly drawn Diac.

Mike.
Edit, it has 1μ above it which suggests a capacitor.

The part with the 'ladder' is simply an electrolytic capacitor - i.e. a polarized capacitor. The cross hatching may be indicative of an aluminum electrolytic or tantalum cap, but it really doesn't matter. It's a cap.

The dotted area shows multiple instances of the same circuitry. Your schematic shows 2 tone related touch switches, while the actual product may have many more. It's just a way of not having to draw the same thing over and over again.

Ah ok, so it is like the Electrolytic (Japan) in the picture below, but just with fewer lines in the middle.

-Also, another quick question when it refers to "touch sensors" does it mean a physical sensor like this-

Or is it just a metallic strip between the two points that just acts as one
