## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0387:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN0387:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The magnetic switch mainly comprises two parts; the inducting end, and the trigger. The former has a reed switch enclosed inside and there is a cable connected to it, and the latter is a magnet enclosed within a plastic case. When the two parts are separated the circuit will be open. When the distance between these two parts is smaller than 1cm, the reed switch will close and a connection will be made. Characterized with reliable performance, long life-span, low power consumption, wide voltage range, and high operating frequency, this magnetic switch is very applicable to harsh environments and can be used in door/window position limiting device, intelligent toilet, car/electrical bike anti-theft, smart home, etc.
