If you want to turn a light on at a certain time every night, then a simple mechanical timer from your preferred hardware or general merchandise store is probably a good choice. If, however, you need extremely detailed control over when and how long to trigger a light, bell, production line equipment, or really anything you need to switch at a set interval, then the Tick Tock Timer by 8Bit Automation is what you want.
Timing patterns, as seen in the video below, can be set via a built-in touch screen. Up to 20 scheduled events can be set up, along with 5 holiday periods where the relay does not come on. It can also be actuated manually, and response to this input can be customized. If that wasn’t enough, it has a security feature that allows for three levels of access.
The housing is 3D-printed, and comes in red, grey, or blue. Though this might seem nice from an aesthetics point of view, I could also see this being important if you want to color coordinate several of these switches for easy access.
