||
| 7 | ** A simple 1,5V Alkali will do. |
||
| 8 | ** -Button can handle 240V- |

| 9 | 2 | Maximilian Seesslen | ** An 18650 is perfect. Along with the MCP73871 or only MAX1811ESA+. No integrated LDO necessary, only SSR is switched. AUR9811DGD only 33 Cents. |
| 10 | 4 | Maximilian Seesslen | ** An 18650 is way too big. We only flash the LED for a short time. Ne Knopfzelle wuerde es tun. |
