Taig Home and Limit Switches

thingiverse

These are a complete set (for X and Y, Z has just one switch) of home and limit switch holders/mounts for the Taig mill, specifically for those with a CNC model. They are designed specifically to utilize OMRON switches (model V-10G6-1C24-K, https://www.mouser.com/ProductDetail/653-V-10G6-1C24-K). You can see the datasheet here: https://www.mouser.com/datasheet/2/307/en-v-952614.pdf The Taig mill's X and Y axis rails (and hence these design files) use 4-40 and 10-32 bolts and square nuts. Here is the necessary hardware to affix the home and limit switches to the Taig mill: The X axis switch mount hardware (fits the Taig X axis t-slot): "Low-Strength Steel Square Nut Zinc-Plated, 4-40 Thread Size" https://www.mcmaster.com/#catalog/94855A281 "Zinc-Plated Steel SAE Washer for Number 4 Screw Size, 0.125" ID, 0.312" OD" https://www.mcmaster.com/#catalog/90126A505 "Zinc-Plated Alloy Steel Socket Head Screw 4-40 Thread Size, 7/8" Long" https://www.mcmaster.com/#catalog/90128A114 The Y and Z axis switch mount hardware (fits the Taig Y axis t-slot, and the two holes on the Z axis): "Low-Strength Steel Square Nut, Zinc-Plated, 10-32 Thread Size" https://www.mcmaster.com/#catalog/94855A283 "Zinc-Plated Steel SAE Washer for Number 10 Screw Size, 0.219" ID, 0.5" OD" https://www.mcmaster.com/#catalog/90126A514 "Zinc-Plated Alloy Steel Socket Head Screw 10-32 Thread Size, 1" Long" https://www.mcmaster.com/#catalog/90128A947 "Zinc-Plated Alloy Steel Socket Head Screw 10-32 Thread Size, 1/2" Long" https://www.mcmaster.com/#catalog/90128A942 The 'side' holes in the designs are for a suitable shielded 2-conductor wire to fit through. You can fill the hole or drill it out accordingly to fit whatever wire you use to affix the switches in your CNC arrangement. I used this wire for my home and limit switches, and the holes are designed accordingly: https://www.amazon.com/Conductor-Stranded-Cable-Custom-Connection/dp/B071DFHKRB/ref=sr_1_1_sspa/146-5759635-1578711?ie=UTF8&qid=1529381780&sr=8-1-spons&keywords=22+awg+2+conductor+wire&psc=1
