Capacitive Touch Wall Switch

Overview

Description

Capacitive touch switches are increasingly being adopted in commercial buildings, hotels, and other hospitality environments, addressing the growing demand for stylish, functional, and smart home-compatible solutions. These switches enhance user experience while offering energy efficiency and hygiene benefits.

This capacitive touch wall switch features a high-voltage buck regulator and a Bluetooth®-enabled MCU. Its simple yet effective design interfaces seamlessly with various light and occupancy sensors, as well as motor controls for blinds and curtains.

System Benefits​:

  • Renesas high-voltage (HV) buck regulators are cost-effective, compact, and simple to design.
  • Zero standby power reduces energy costs and environmental impact, with efficient performance from light to full load.
  • Improved EMI by jittering and enhanced gate drive ensures stable, reliable switching performance.
  • Noise-free operation avoids functioning in the audible range for a better user experience.
  • The 32-bit MCU with Bluetooth Low Energy (LE) enables smart features and connected home system controls.
