#174607 - Remember that there is more than push buttons out there Responding to: ???'s previous message |
Pushbuttons other other switches used in keypads should normally have quite short bounce times.
The really long bounce periods is more common when having flip-type or rocker switches. And they may also be highly asymetrical. And their internal design may be 100% controlled by a spring, making it impossible for a user to increase the contact pressure - all we can do is try to remove contact pressure by trying to hold it between the two states. |
