The large amber surface of this switch gets VERY hot after being in the ON position for a few minutes - so hot that after less than an hour of use I replaced it with a similar round Hella switch with a small one have green diode completely cold during use. After sitting in my parts cart for over a year I decided to try again as the app requires a yellow switch. 10 seconds use. The switch still powers the device I used it for - just its amber light is off, which may be acceptable for some applications but not mine. I suggest avoiding this switch and instead using a similar round Hella switch with a small cold burn diode.
