Tim,

Try Radio Shack P#'s 275-651 and 275-654 for SPST and SPDT/Center Off, repectively. Radio Shack does not have any Double Throw switches in that line, but the GC brand (P# 35-189) is a very close match and is available in DPDT/Center Off. The GC switches will have to be obtained from a commercial electronics distributer such as Newark Electronics.
Hope this helps.

Steve
