Red LCD switch

Hello

I'm new on here so please bear with me.

I've recently purchased the Arduino Mega2560, RAMPS 1.4 boards along with the reprap discount smart controller.

I have the basic components working and I've attached 2 thermistor and the display but that's all right now, other parts are on order. The display works, buzzer works, and push button knob works. What I'm curious about it the other red pushbutton switch. What is it normally used for?

thanks

I don't see any red buttons at all, but they one on the RAMPS board and the one on the display are both reset buttons that mirror the function of the reset button on the Arduino. They reboot the Arduino.

The photo is just dark, it's actually red. Anyway, I must have missed it in the firmware, right now it does not do anything. A searching I will go.....

thanks

I think it's in pins.h in Marlin.

As it turns out "pins.h" looks for a board type an in my case calls "pins_ RAMPS_13,g"
"pins_RAMPS_13" checks the display type and in the case of the "reprap discount smart controller" sets it to a "Kill" switch.

thanks for the help
