A symbol often used in circuit diagrams is like an upside down tree, a bit like this:

" "" "" "" "" "" "" "" "" "" "" "" " |

" "" "" "" "" "" "" "" "" "" "" "--------

" "" "" "" "" "" "" "" "" "" """ "------

" "" "" "" "" "" "" "" "" "" "" "" "---

" "" "" "" "" "" "" "" "" "" "" """" -

(Please ignore the "" marks, they are needed to stop the spaces being deleted by the hypertext system that's used here!)
