Relay Boards

[David Root]

I don't see the problem. You can mount a DIP on the eyelet board same as a separate relay board. Just make the eyelet board a bit wider or longer.

Here's the obstacle. The flanges on eyelets are so big, if you put the eyelets close together so they mate up with relay pins, the flanges touch, and everything shorts out.

Last night I soldered wires to the pins on a relay, flipped it over so the pins were facing up, bent the wires so they pointed in the opposite direction from the pins, and secured them to the relay with a cable tie to provide strain relief. It works, but it's not something you would be eager to display in a gut shot.

Is there any respectable way to mount a relay on an eyelet board? [...] Here's the obstacle. The flanges on eyelets are so big, if you put the eyelets close together so they mate up with relay pins, the flanges touch, and everything shorts out.

As I posted you can get 1/16" eyelets from mouser:

Mouser Part #: 534-25

I unfortunately forgot to edit this to be 1/16" x 1/16" for thinner G10 but if you have 1/8" thick G10 to use, these are the little eyelets that are about as big as one pin on a DIP socket or the relay. Gotta be accurate with the drill though. What eyelets were you using?

Steve, you are correct. However, it can be carefully done if you use 1/16" or 3/32" eyelets for the relay pin sockets. The smaller diameter eyelet of course will have a smaller topside flange. The eyelets are tied together with 22awg buss wire.

Here's a couple; one with 1/16" eyelets to outboard 3/32" eyelets and another with DIP sockets and 3/32" eyelets to outboard terminals.

Great info. I had no idea those things existed.

More stuff to order, I guess.

Structo Regarding the non latching i think you n i are saying the same thing, which is why im confused. If it doesnt stay connected, it would switch the effect.channel.pab in, then right back out...?

Here is the diagram for the relays we use.

There is the common lugs which are #4 and 13.

Then there is the normally closed, 6 and 11.

The 8 and 9 lugs are normally open when no current is present.

When no current is on the coil, 4 and 6 are connected as well as 13 and 11.

When the coil is energized, now 4 and 8 are connected as well as 13 and 9.

It is a Double Pole Double Throw switch.

Hope this helps.

structo/tom thanks again. I understand the way the actual relay works.

I think I have it, though, a latching footswitch is needed to switch properly with the relay.

If I run without boost, and want to switch in boost, I depress the footswitch (latching) and it will connect to the relay, switching open the NC connection, and closing the NO. The footswitch is latching, and will therefore continue to give power to the relay which will keep the NO closed until I depress the footswitch again to turn it off.

[David Root]

Actually the ones we use are "non-latching". I'm really not too clear on the difference. But non-latching relays are not momentary contact switches, as long as the current is on the coil they stay in the NO position.
