Because I moved the PSU of my Kossel to the back I wanted the on/off switch at the front.
The mounting plate is designed for the AnyCubic-Kossel and for a switch that will fit between the horizontal 2020-rods of the underframe.
Used switch is the low profile and single pole RH-switch: http://www.canal.com.tw/images/products/rh.htm
There are two versions, a 40 mm deep version which also protects the connectors and a 23 mm version which leave the connectors unprotected. Use the 40 mm one for higher voltages and please be careful when you are working with electricity. Don't use it when you are not certain what you are doing. You can seal the backside of the long version after cabling and checking by heating it up (for PLA) and pinch it together.
The 23 mm version can also be mounted from the inside out for a cleaner look (see pictures)..
If you want to customize it, there is a dxf-file included.
Happy Switching :)
PS. The model of the Kossel used in the pictures is from Master_Aar: thing2965780
