Keyboard Key Life Testing Machine

The Keyboard Key Life Testing Machine is designed to evaluate the durability and lifespan of keys and buttons across electronic devices. It is suitable for testing keys on mobile s, MP3 players, computers, electronic dictionaries, remote controls, silicone rubber keys, and other silicone products. The machine supports multiple key types including mechanical switches, film switches, and tap switches. Adjustable speed, configurable number of actuations, and multi-station testing ensure precise and flexible testing for various key designs and customer requirements.

Application

(1) Life cycle testing of mobile keys, MP3/MP4 buttons, computer keyboards, and electronic dictionary keys.

(2) Durability testing for remote control buttons and silicone rubber keys.

(3) Verification of mechanical switches, tap switches, and film switches.

(4) Multi-point testing on each key to simulate real-world usage.

(5) Research and development for new key materials and designs.

(6) Quality control in electronic and consumer device manufacturing.

(7) Testing under varying key pressures and stroke heights to replicate user behavior.

(8) Comparative testing for different key types and configurations.

Standards

(1) GB/T 4967-95 – Silicone rubber and keypad life testing.

(2) Equivalent JIS and IEC standards for key life and durability testing.

Features

(1) Motor-driven eccentric mechanism provides precise vertical motion to actuate keys.

(2) Adjustable test speed from 5 to 60 times/min.

(3) Multi-station testing: 4, 5, or 8 stations can operate simultaneously.

(4) Individual control of each test head for custom pressure and stroke height.

(5) Configurable test load from 0 to 500g (or specified by customer).

(6) User-friendly operation and flexible fixture design for various key types.

(7) Digital counter records the number of key actuations for accurate life assessment.

(8) Allows simultaneous testing of multiple products at different points.

(4) Multi-point testing heads for precise key contact.

Test Procedure

(1) Secure the key or keypad sample on the test station fixture.

(2) Set the desired test speed, stroke height, and load for each test head.

(3) Select the number of actuations for the test.

(4) Start the motor-driven test; each key is actuated according to the settings.

(5) Monitor digital counters to track the number of presses.

(6) Upon reaching the set number of actuations, stop the machine and evaluate the keys for wear, functional failure, or other defects.

(7) Record the data for quality control or product development purposes.

Maintenance Information

(1) Keep test heads and fixtures clean to prevent damage or contamination.

(2) Inspect and maintain motor and eccentric mechanism periodically.

(3) Verify calibration of test load and digital counters.

(4) Ensure power supply stability and check wiring connections regularly.

(5) Store the machine in a dry and dust-free environment.
