Causes of double-tapping issues
Damage to the switch can cause double tapping or non-responsiveness. The most common cause is either manufacturing defect or switch modifications. Switch modifications like lubing and filming can introduce dust particles and cause double-tapping. Internal components of a switch are highly sensitive so please exercise extreme caution when modifying a switch.
High number of hard presses can potentially damage the internal components of the switch, causing it to register multiple times. In our testing, We set up a rig to pound each key with 30 pounds of force at 2,500 RPM. The rig pounded the keys over 1,000,000 times and we observed no
changes in performance.
1,000,000 keypresses is equivalent to single-tapping Road of Resistence [Monstrata] 600 times consecutively.
Switches that are not properly seated in the hot-swappable sockets can also cause double-tapping.
Solution: replace the switch with another switch to test if the switch is causing double-tapping. If so, try seating the switch again and see if the issue persist. Otherwise, a replacement switch is needed.
Dust particles in sockets
Dust particles can cause issues with the sockets since the hot-swappable sockets are highly sensitive to disruptions.
Solution: in our testing, a blast of compressed air into the switch sockets can potentially help fix the double-tapping issue.
Improper swaps and excessive force
Our last test was conducted with a team of engineers from Kailh, the manufacturer of the hot-swappable sockets. Kailh hot-swappable sockets are rated for 100 swaps before any signs of deterioration.
Kailh engineers concluded that the double-tapping issues are caused by user error.
When replacing switches, it is highly likely that improper swaps and use of excessive force can shorten the lifespan or cause permanent damage to the sockets. If the pins are not aligned with the socket holes, it will move the socket out of place or even break apart from the PCB. This will cause detection issues or non-responsiveness.
We ran tests to see if inserting switches at different angles with varying degree of force causes socket damage. We found that the sockets can be damaged if the pins are not aligned with the socket and excessive force is used.
We believe this is the main cause for double tapping issues
Solution: Please contact us immediately if your keypad is within warranty period and we can see if a replacement PCB can be sent out to you for repair. If your keypad is outside of warranty period, we sell replacement PCBs on our store.
