Magic Cup Tilt Switch Module KY027

Magic Cup Tilt Switch Module KY027

The KY‑027 Magic Cup Tilt Switch Module integrates a mercury tilt switch, LED, 10 kΩ series resistor, and 4-pin male header on a small PCB (approx. 18.5×14 mm). When the module is tilted or vibrated, the internal mercury switch closes, activating the onboard LED and authorizing a digital state change on the “S” output pin. This trigger can be forwarded to microcontrollers like Arduino, ESP32, Raspberry Pi, or Pico for programmable interaction.

Features

• Built-in mercury tilt switch detects motion or orientation change.
• Onboard LED illuminates when tilt switch closes.
• 10 kΩ resistor pre‑installed for power usage compatibility.
• Signal output (“S”) pin reflects tilt state digitally.
• LED control input (“L”) allows PWM brightness control.
• Supports both 3.3 V and 5 V systems with required series resistor (120 Ω for 3.3 V, 220 Ω for 5 V).
• Low-power standby; lightweight (~2 g) and compact footprint (36 × 15 × 14 mm).

Specifications

PINOUT

• ‘G’ / ‘–’  = Ground
• ‘+’ = Vcc (3.3 or 5V to match uControllers)
• S = Output of the tilt switch.  Connects to a digital input pin on uC.  Active LOW
• L = Input to drive LED.  Connects to a digital output pin on uC.  Active HIGH

Applications

• “Magic light cup” interactive effects: two modules controlling each other’s LED brightness via tilt and PWM.
• Motion or vibration-triggered lighting or status indication.
• Simple tilt alarm or tilt-detection circuit.
• Input device for interactive displays, toys, and art installations.
• Reaction-based IoT prototypes and sensory feedback systems.
