I've got a radio with a bass boost toggle switch on it but it always
resets to "off" when the power is reset. I assume its some kind of
standard electronic toogle switch arrangement. An LED comes on when
the switch is "on".
I thought about simply wiring the switch permanently closed (would be
like someone holding the switch down all the time) but would this have
an adverse effect on the rest of the electronics?
What can I do to make this switch have power independent memory? Can
I wire up a latching relay in parallel with a kind of feeback so that
when the switch is pressed it closes the circuit? Then when the radio
is powered up again the circuit would already be closed. Pressing the
switch again would (hopefully) open the latching relay.
Would one of these

do the job or do I also need to circuit to figure out the toggling??
Thanks I'm a bit of a novice when it comes to things like this!!
