About

I want to build a simple automatic dust extractor switch box — basically the same idea as this one: https://www.timbecon.com.au/products/ivac-automated-dust-extraction-control-switch-box-anz-version …but rated for 15 amps at 240 volts. When the table saw turns on, the box should automatically power the dust extractor, with a short start delay. When the saw turns off, the extractor should keep running for a few seconds, then shut down. What I need: A wiring diagram and clear layout A full parts list sourced from Digi-Key, Element14, or RS Components New Zealand (no random eBay parts) Recommendations on reliable relays, timers, and contactors suitable for 240V / 15A Simple, robust design — ideally plug-and-play with NZ/AU sockets Basically, I want something that’s solid, serviceable, and made from parts you can easily order from proper suppliers. If you’ve built or designed anything like this before (dust extractors, saw interlock boxes, automation gear, etc.), I’d love to see examples. Would you like me to make a matching job title and skill tags list for Upwork so it attracts the right kind of engineer (e.g. industrial control / automation techs vs PCB designers)?
