SW-200D Green Double Ball Rolling Vibration Sensor Switch

SW-200D is a dual ball type single direction tilt sensitive trigger switch. It is commonly used in automation devices. Hobbyists also use it  on robotic chassis. When the device tilts to the conductive terminal (silver pin end – A) by more than 10 degrees, it will be at open circuit “OFF-state”. When its horizontal postion changes, the trigger terminal (gold-pin end B) is below the horizontal tilt angle and more than 10 degrees, it will be at closed circuit “ON-state”.
