Tilt Switches

1. What are Tilt Switches?

A tilt switch is an electronic switch based on gravity sensing or a mechanical pendulum. It triggers an on/off signal when the device’s tilt angle exceeds a preset threshold. Its core components include:

Mechanical: An internal mercury bead or steel ball moves with the angle to contact an electrode.

Solid-state: A MEMS accelerometer detects angle changes.

The trigger angle range is typically ±15° to ±180°, with an accuracy of ±1°.

 

2. Key Parameters of Tilt Switches

Parameter	Typical Value	Description
Operating Voltage	3.3V-24V DC	compatible with industrial-grade power supplies
Contact Capacity	0.1A-5A	must match the load current
Repeat Accuracy	±0.5°	mechanical type slightly lower than solid-state type
Protection Rating	IP65/IP67	waterproof and dustproof

 

3. What are the Typical Application Scenarios of Tilt Switches?

Industrial Safety: Tilt alarm for heavy equipment (e.g., forklifts and cranes).

Consumer Electronics: Laptop drop protection, smart speaker auto-sleep.

Automotive Electronics: Rollover detection, trunk status monitoring.

 

4. Selection Recommendations for Tilt Switches

Prefer models with self-locking functions (e.g., G-Sensor + MCU solutions).

For vibration environments, pay attention to anti-interference parameters (e.g., 10-2000Hz vibration resistance).

For high-temperature applications, solid-state models are recommended (operating temperature -40°C to 125°C).
