Математический лабиринт
The working principle of a Pat-Pat Lamp (also known as Knock-Knock Lamp) is based on a vibrate-triggered switch circuit. It typically consists of a mechanical oscillator and a circuit board. When the mechanical oscillator receives an external tap or vibration, it produces mechanical vibrations that cause the metal ball on the circuit board to touch the metal contact, thereby completing the circuit. The momentary change in current is detected and used to control the switching of the lamp. Therefore, the Pat-Pat Lamp can be turned on or off by tapping or lightly knocking on it. This design is sometimes used in energy-saving lamps because it only needs to turn on the light when needed, instead of keeping the light on all the time. SW-18015P is spring type, Non-direction vibration induced trigger switches, any angle can be trigger. The series of switches, at the rest is open circuit “OFF-state”, When the external force to touch and reach the corresponding vibration, Or move in speed to reach the adequate centrifugal force. The conductive feet will be conduct instantaneously “ON-State”. When the external force disappear, the switches will be revert the “OFF-State”。 #vibrationswitch #patpatlamp #GBeeLee #electronic
