Frequently Asked Questions
Q: What is a one-touch power switch module and how does it work?
A: A one-touch power switch module is an electronic circuit that toggles a connected load (e.g., a light, motor, or device) on or off each time the button is briefly pressed. Unlike a mechanical switch that physically opens or closes a circuit, this module uses electronic components to latch or unlatch the output — resulting in quieter operation, longer lifespan, and a lower profile design ideal for modern electronics projects.
Q: Is this module compatible with Arduino and Raspberry Pi?
A: Yes. The Keshy one-touch power switch module supports working voltages from 3.3V to 20V, covering the 3.3V used by Raspberry Pi GPIO logic and the 5V used by most Arduino boards. It can control loads of up to 11A, making it versatile for a wide range of microcontroller-based builds.
Q: How much power does this module consume when the load is off?
A: The module draws only 0.01mA in its static (standby) state, which is extremely minimal. This makes it an excellent choice for battery-operated devices where preserving power between uses is important.
Q: Can this module replace my existing mechanical power switch?
A: Yes — this module is specifically designed as a drop-in electronic replacement for traditional mechanical switches. It handles the same on/off function but without physical moving parts, reducing wear and offering a cleaner, more modern user experience.
