Description
This bracket holds an emergency stop button with a 20mm mounting hole. The flanges are sized to match the 20mm Mitsumi extrusions used on the MendelMax
Instructions
Slide your emergency stop button/switch through the mounting hole and tighten. Use two 4mm screws to mount it to the extrusion.
I have wired mine into the 12V line leading to my RAMPS board. If anything goes wrong just hit the button and all the motors and heaters shut down immediately.

Hi
You say you wired yours in series with your main 12V supply... did you check the maximal current of the switch ?
Most are only rated to 10A, and I believe your printer may use much more than than (with the heaters).
Exceeding the maximum rating of a switch may :
- Cause a switch malfunction, making it unable to stop the current the day you need it to
- Cause a fire hazard in some cases
Just a heads up

Just to be safe, it might be a good idea to move the switch to the AC side of the circuit. I am using an 8 amp supply so it would definitely fall within the rated range of the switch. It is up to each person to check the ratings of their equipment before they make any additions or modifications.
Thanks for the heads up. According to the spec sheet this switch is rated for 1200 watts. I am running 12 volts at 15 amps for a total of 180 watts so I am well below the rated power.
