Soft Power Swich - USB Type C - SparkFun PRT-27081
Soft Power Switch with USB Type-C from SparkFun is a power switch that works on the principle of a passive button, but with the possibility of control via software. The button works similarly to a laptop power button: a single press turns the system on, and another press (after intervention by the microcontroller) can turn it off. If problems occur, just hold the button for about 10 seconds to force the system to shut down.

Product description: Soft Power Switch - power switch - USB Type-C - SparkFun PRT-27081
The SparkFun USB Type-C Soft Power Switch is a power switch that works like a passive button, but can be controlled via software. The button works similarly to a laptop power button: a single press turns the system on, and a second press (via a microcontroller) can turn it off. If problems occur, simply hold the button for about 10 seconds to force the system to shut down . The switch is ideal for Thing Plus-based projects and other devices where you need an easy way to control the power supply. It offers two USB Type-C connectors, as well as a version with 2 mm JST connectors for connecting a battery. It features a robust, digital design based on Texas Instruments circuits and provides very low power consumption in standby mode, which translates into energy savings in battery-powered devices. Equipped with LEDs to indicate the power status (input and output), as well as a 2 A fuse, providing protection against overloads.
