This product is the GDT Switch Timer COC-02WT, a timer designed to automatically press physical switches. It can automate switch operations for things like lighting and coffee makers. No smartphone or Wi-Fi environment is required; timer settings can be configured directly on the device. You can select from three operating modes: push-type, seesaw-type, and long-press type. It can be easily installed with double-sided tape, and no construction is required. I was using it as an automatic timer for my air conditioner, but I no longer need it, so I'm selling it. Includes the instruction manual.
