KKUANG 25PCS SW-520D Ball Vibration Switch Suitable for Toys Electronic Gifts Motion Sensing Interactive Devices

["You will receive 25 pieces SW-520D ball-type vibration switches.","Dimensions: 22.8x5.5 mm/0.9x0.21 inch, see the image for exact dimensions","This product is manufactured from metal and features a unidirectional angle-trigger mechanism. It exhibits sensitivity to tilt angles and vibration amplitude, whilst maintaining a compact form factor.","The switch incorporates a metal ball internally. When tilted, subjected to vibration, or rotated to a specific angle, the ball contacts different electrodes, thereby completing or breaking the circuit to output a switch signal. The switch is in the closed position when horizontal, it is in the open position when raised between 10 and 90 degrees.","Widely employed in toys, electronic gifts, vibrating alarm clocks, motion-sensing interactive devices, and security installations requiring posture detection."]
