... and for the next project of this type, I'll make life simpler for myself and use:[warming the TRIAC will make it more likely to flash on turn on which can help with tedious on off testing.]
... or one of these:The dV/dT rating of the MOC is a lot higher than the chosen TRIAC, given that the load is*tiny* the MOC can probably drive it all on its own. 20mA is not a lot.
~Mf all else fails try replacing the MOC and TRIAC with a SSR like one of these https://www.openhacks.com/uploadsproductos/g3mb-ssr-datasheet.pdf
