Secure Remote Mains Switch, Part 2 - August 2022 - Silicon Chip Online
This Remote Mains Switch uses a high-security rolling-code system, so it is suitable for triggering motors that open doors or gates. It’s also very robust, allowing it to switch motor-based appliances like pool pumps and water pumps. Last month, we described the circuitry; this article concentrates on its construction, testing, set-up, and use. by John Clarke
