OT: CW Paddle A/B switch

I have two radios and one cw paddle. I'm looking for a small inline A/B switch as would be used on stereo headphone sets to switch between sources. The whole thing would be a "Y" cable with two 1/8" male stereo plugs on one end and a single female jack on the other. Switching would choose which male plug is active. Yes I can build one but before I reinvent the wheel, I thought someone might have a source.

I'm tired of plugging and unplugging and I don't want or have the extra space for another paddle.

Has anyone found such a switch?

Reply by private email please as this is off topic.

Thanks,

Doug W5JV

Re: OT: CW Paddle A/B switch

A question. Do you really need a switch? Are both rigs going to be on at
the same time? If not a simple headphone splitter should do the trick.

Re: OT: CW Paddle A/B switch

Why a switch. Unless you’re gonna have both rigs on at same time.

A simple “Y” adapter would seem easier.

Re: OT: CW Paddle A/B switch

A spst switch on one “hot” line will suffice and let you use both rigs at
the same time. No need for a splitter. Wire both to the key with switch
line going to one rig.

Re: OT: CW Paddle A/B switch

In reply to this post by Jim Rhodes-2

If two entirely different rigs pull paddle inputs up to different voltages
(say 5 and 12V), and with the paddle lines tied together, current may flow
from one rig to the other when the paddle is not pressed. A turned-off rig
might float or might pull down a paddle input. I'd measure the current flow
in the various scenarios (one or the other rig on/off, paddle inputs not
grounded). A few diodes might remove potential problems.

If two rigs are turned on (for whatever reason), would you want them both
keyed?

I'd personally favor a switch, and consider microphone, PTT footswitch,
keying lines with that same switch. But that's possibly a lot more complex
than you need.

I bought an NCS-3240 Multi-Switcher some years back but haven't pressed it
into use. It switches microphone and key line, but assumes an external
keyer rather than one built into the radio.

I personally found it less work and more flexible to use different paddles
and different microphones.

Re: OT: CW Paddle A/B switch

In reply to this post by Doug Hensley

Hi Doug,

I am currently using two of the following switches and they work
perfectly.They switch 1/8" stereo plugs so if you are currently using 1/4"
plugs you would need reducers.

https://www.amazon.com/gp/product/B00NTKFKMG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I use my K3 for local operation and with an RRC device for remote operation.
I use one switch for my headphones and another for my microphone. I would
have a third switch for my paddle, however, I had previously made a toggle
switch box for that purpose.

73,
Mike K2MK
