Test Standards:
GB/T4967-95 silicone rubber and key life test is equivalent to JIS IEC related standards

Test theory:
The key life testing machine uses the stepping motor drive eccentric structure to move the worktable up and down, so as to make the key or keyboard move relative to the probe. Set the test times of the counter. After the times arrive, check the damage of the key, so as to judge the quality and service life of the key.
