## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TEL0173:1` (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/TEL0173:1.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 self-powered wireless switch series by DFRobot advances the traditional wireless control paradigm by completely removing the need for batteries. This next-generation self-powered wireless switch - BLE Beacon, unlike its predecessor,[ the self-powered wireless switch - 433MHz](https://core-electronics.com.au/self-powered-wireless-switch-433mhz-1.html), features a micro power generator and an energy storage RF circuit that **captures kinetic energy from each press, converting it into electrical power**. This energy is then stored and utilized to transmit wireless signals, making the switch maintenance-free and **ideal for long-term applications like wireless doorbells, call buttons, ordering devices, and wall switches**.

**Self-Sustaining Power Generation**

This new model eliminates the need for batteries, addressing common issues such as battery replacement, corrosion in humid environments, and environmental pollution from battery waste. The self-sustaining power mechanism ensures uninterrupted operation and significantly reduces maintenance efforts.

**Enhanced Wireless Signal Capabilities**

The switch offers robust wireless transmission without the need for wiring, ensuring flexible and hassle-free installation. The latest BLE beacon version supports BLE 5.3, enabling seamless integration with smartphones and other Bluetooth-enabled devices for versatile control applications. Compared to the previous 433MHz RF version, the BLE beacon provides faster transmission rates (1Mbps vs. 10kbps) and enhanced anti-interference capabilities with GFSK modulation.

**Unique Address Code for Secure Transmission**

Each switch is equipped with a unique 6-byte address code, guaranteeing secure and reliable signal transmission without interference. This feature ensures consistent performance even in complex wireless environments.

**Improved Durability and Press Performance**

Designed for durability, the switch can withstand up to 100,000 presses. The BLE beacon version features a lower press force requirement (1300g vs. 1800g) and a shorter press distance (1.3mm vs. 2.6mm), offering better tactile feedback and user experience. The power efficiency is also enhanced, requiring only 250uJ per press compared to the previous 600uJ.

**Enhanced Application Suitability**

The BLE beacon version is particularly suited for users familiar with ESP32 and other Bluetooth-enabled MCUs or those integrating with smartphones. It eliminates the need for a dedicated receiver, offering greater flexibility. While the 433MHz version remains ideal for scenarios requiring penetration through multiple walls due to its strong penetration capabilities, the BLE version provides superior anti-interference performance and faster transmission, making it a more advanced choice for modern applications.

The upgraded self-powered wireless switch series offers significant improvements in power efficiency, signal transmission, and user experience, making it an essential component for long-term, maintenance-free wireless control solutions in various applications.
