| Subject: | How to wire switch |
--> AeroElectric-List message posted by: Speedy11@aol.com
I need to attach multiple wires to a rotary switch so as to make an engine
monitor display indications from three inputs. As I look at the switch, I'm not
sure how to connect the wires to the tiny connections on the back of the
switch. I know which places to make connections, just not how to mechanically
connect.
I'm wondering if there are fast-ons that are that small or if I'm supposed to
simply solder the wires to the little connections?
A photo of the switch is at http://www.rv-8a.net/electrical.htm.
Help anyone?
Stan Sutterfield

The connectors have holes in them...I pass the wire through the hole, twist it
back around itself and solder....
The twisting back is optional - holds it in place while I solder........

I would also throw a chunk of clear heatshrink tubing on it after.......

Yes just solder those Stan. Remember to "tin" the wires first and then
solder together....Using a short piece of heatshrink over the joint
would be perfect.

Ah, the evil wafer switch. Nasty things those. We hates them forever.
(As a kid I built my own ham and test equipment and would end up wiring
up switches like that with as many as five wafers! It taught me patience
and to take extra care to get things just right the first time. The
first time you have to remove and rewire a wafer switch makes a real
believer out of you.)
Wire and solder is the short answer but there are some other
considerations. If you only have to attach one wire per terminal it
isn't too bad. Two is a pain. Three is impossible. If you have to attach
as many as three wires to a terminal you might want to consider bringing
your connections out to a connector and attaching the rest of your
harness there. A small circuit board is a possibility as well.
Attach all the wires to the switch and then use some kind of connector
or knife splices (on second though, forget the knife splices) to connect
the switch to the rest of your harness. It will just make things a lot
easier to work on later when you need to remove the wafer switch to
clean it or replace it.
Also, my experience is that the terminals on the switch are almost
always oxidized and won't take solder very well. Find some way to clean
and burnish the terminals before putting your wires on there. Failure to
do is it asking for a poor solder joint and failure later. Clean and tin
the terminals then use a solder-sucker to pull off the excess solder.
That will leave a good tinned terminal that will let the solder fully
wet the joint.
Good luck and have fun.

Stan,
Those are solder tabs. My process steps would be:
1) slide a piece of shrink tube on the wire (and push a good couple of
inches away from the end)
2) strip the end about 3/8" to 1/2"
3) bend a hook in the bare wires, and hook it in the hole on the tab on
the switch
4) squeeze the wires flat against the tab
5) solder
6) slide the shrink tube over the tab
Bob probably has pictures on how to do this somewhere on his website...
