Technical Analysis of Rolling Ball Tilt Switches

Author: Cheng Shengxing Electronics

Working Principle and Core Structure
A rolling ball tilt switch (also known as a steel ball switch or tilt switch) is a mechanical sensor that triggers circuits via gravity. Its core structure consists of a metal ball, conductive electrodes, and an insulating housing. When the device is horizontal, the ball rests in the center of the insulating cavity, leaving the circuit open. Once tilted beyond a set angle, the ball rolls to touch the electrodes, closing the circuit and triggering a signal.

Types and Technical Parameters

Directional Type: Responds only to tilts in specific directions (left/right, front/back). Classic models include CSX-SEN-360A and CSX-SEN-360T.
Omnidirectional Type: Triggered by tilts in any direction (e.g., CSX series).
Optical Variant: Contactless design (e.g., CSX45PS) using the ball to block an infrared light path, avoiding metal oxidation and extending lifespan.
Key parameters: tilt angle accuracy (±5°), temperature resistance (-40°C to +85°C), protection rating (IP67), and current load (≤250mA), suitable for low-current signal activation scenarios.

Advantages Over Traditional Solutions

Eco-Friendly and Safe: Completely replaces toxic mercury switches, complying with RoHS standards.
Energy-Efficient and Miniaturized: Ultra-low power consumption (μA level), with SMT-compatible packaging as small as 0.8mm.
Anti-Interference Design: Incorporates limiting steps and adjustable delay circuits (0–10 seconds) to suppress vibration-induced false triggers.
