Re: Switch debouncing

If you can use a SPDT momentary switch, here's an easy way to debounce:
Connect 2 2-input NAND gates in a latch configuration (Output of gate
A to one input of gate B; Output of gate B to one input of Gate A.
Connect the two "fixed" switch terminals to the two remaining gate
inputs. Connect the "swinger" of the switch to ground. This circuit
will de-bounce for an indefinite bounce period. The only restriction
is that the switch "swinger" can not bounce between the other 2
contacts. This should not be a problem. I've never seen a SPDT swith
(or relay) that does this.
