The Pixhawk Safety Switch and Buzzer Set is a mandatory accessory for any Pixhawk or PX4-based drone, available at RoboShop BD. The safety switch acts as a physical hardware lock that prevents the motors from spinning until manually pressed, while the high-decibel buzzer provides critical audible feedback on flight status, battery warnings, and arming readiness. This set ensures both the pilot’s safety and a clear understanding of the drone’s internal state through multi-tone alerts.
