NE555 Time Delay Switch Module 5V

The NE555 Time Delay Switch Module (5V) is a compact and adjustable delay control module based on the popular NE555 timer IC. It allows you to turn a relay ON or OFF after a preset delay time, making it ideal for automation, protection, and sequencing applications. The onboard potentiometer enables easy adjustment of the delay duration without additional programming or components.
