How to wire Schindler HT Call Buttons

(12-4-18) In today's elevator part video, I show you a way of making a Schindler HT Call button light up by making some custom modifications to the button. NOTICE: This project requires soldering. If you do not know how to solder, see if you can get somebody else to help you. The parts you need are shown in the video. If you have any questions about any of the parts, please let me know in the comments! Also, I am aware of the no sound at the end of the video. Not sure what happened there. When I was pointing out the black and purple wires, I was explaining how the black wire needs to be soldered to the "C" pin on the switch and the purple wire needs to be soldered to the negative pin on the LED.
