What does SA stand for

[CyberGeezer]

Sorry, off topic.

I'm trying to repair a Radio Shack multitester.  I have a
schematic for it.  Shown in the schematic are two things I
don't recognize, designated SA1 and SA2.  The symbol for
them is like
------|0|-------
i.e., a small circle that looks like it's jammed between
the plates of a capacitor, and then with a slightly larger
circle around the "capacitor".

Anybody know what these are?
