Hello Everyone!
Each actuation is recorded via test software so we can determine the point of failure of the switch.
The machine is testing the following...
3x single sized keys with the actuator striking dead centre 1x 1x1.75 key with the actuator striking as far off centre as possible 1x 1x2 key with levelling mech being struck as far off centre as possible
Striking the wider keys off centre tests the switch with side loading as well as testing the levelling mech itself.
Switches being tested are MX1A-G1DN soft-tactile (brown stem).
The test will run 24/7 to the point of failure with inspection at 1,000,000 intervals
This machine has been used to prove how durable Cherry MX switches are - in one case, a batch of MX reds lasted well over their 20 Million key stroke life! (they stopped the test at 30 Million).
