Drag chain and switch type.

[Lee Roberts]

Hi,

I don't think there is a go-to for this (energy chain) and people just source it from wherever, you can get it all over ebay but keep an eye out as some don't allow you to get the cables in like your after without threading it in, this version has quite good feedback: 15x30mm Black Semi Enclosed Towline Cable Chain Drag Carrier Track

Igus make a very nice one with quite a few options: Energy Chains Overview e2.1

and I know a few of our members have used the one available from Motedis a UK company: https://www.motedis.co.uk/shop/table...hp?table_id=52, if you let them know your coming from mycncuk you may also get a discount

Re Switches:
Most are using proximity switches/sensors rather than micro switches now days, below is a video showing some differences so you can get a better idea on how they work and how you can use them, 1 at each end of an axis with a moving "target" to trigger...simple's !
