When the product is inclined to the conductive end (end A without legs) and the inclination angle is greater than 15 degrees, it is in an OFF state. When the horizontal state of the product changes inclination, the trigger end (gold-plated pin end C) is lower than the horizontal and the inclination angle is greater than 15 degrees. When the angle is in degrees, the path is ON.

1. SW-520 is a double-ball tilt-sensing unidirectional trigger switch.
2. When the product is inclined to the conductive end (end A with no legs) and the inclination angle is greater than 15 degrees, it is in an open-circuit OFF state. When the horizontal state of the product changes inclination, the trigger end (end C with gold-plated pin) is lower than the horizontal inclination angle and greater than 15 degrees When the angle is in degrees, the path is ON.
3.When placed horizontally, shaking can be easily triggered. When the golden feet are up, shaking is not easy to trigger.
4. The product of this specification is a completely sealed package, which is waterproof and dustproof.
5. Under normal use, the switch life can reach 100,000 times.
6. The switch material is ROHS environmentally friendly, which completely replaces the mercury switch.
7. The switch signal is simple, the circuit design is simple, and the price is economical.
