Morse Device Circuit

Here’s a dead simple one, the circuit for the Morse Device. This uses just 4 components: an input jack, and output jack, a momentary DPDT footswitch and a latching DPDT footswitch. The latching footswitch could be a SPDT but as I have a fair few DPDT around I tend to use that.

What is going on here is pretty easy to explain. Basically the two footswitches control if the signal is connected to ground or not. If it is the signal is muted, else it reaches the output jack unaffected. The latching switch determines which throw on the momentary switch the signal connects to, which in effect reverses the NO/NC action of the momentary switch.
