A320 Eng/APU Fire Control Panel Light
Stuck again, and need some help.
We have a single lamp out in our A320 Simulator's Eng/APU fire panel, the Engine #1, Agent #1, Left hand DISCH light, It has a broken spring that cannot be fixed. Looks like all of DISCH lights are the same, but no one can verify the part number of the switch. Looked up the part number in the A-320 IPC and it shows P/N: E0415B3E for the switch and 0L718297 for the lamp. Did some internet searching, and the part number that comes up is ASNE0415B3E.
No one seems to want to sell just one little switch. 
Any ideas?
