This relay . . . http://search.digikey.com/us/en/products/G5V-2-DC12/Z768-ND/87821 is suited to the task and fits in this socket http://search.digikey.com/us/en/products/4-1571552-2/4-1571552-2-ND/2258924 Bob . . . ________________________________ Message 3 _____________________________________ Time: 09:46:23 AM PST US Subject: AeroElectric-List: Re: PTT Y adapter for RST intercom From: "messydeer" Thanks, Bob :-) I understand these relays can be soldered to a perfboard. Joe had mentioned this, and I sorta forgot about the socket. Is there an advantage in using a socket, or could the relay be just as easily soldered directly onto a perfboard? I'd only be getting two of them and they're real cheap, so cost isn't an issue. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=359477#359477 ________________________________ Message 4 _____________________________________ Time: 09:50:58 AM PST US Subject: AeroElectric-List: Re: PTT Y adapter for RST intercom From: "user9253" Attached is a schematic that I drew of a single relay interface between RST-442 & Com radio. Only one MIC can be connected to the radio at a time. I do not know if having the co-pilot MIC always connected to the radio hurts anything. What do you think?

I think it is a matter of personal preference. A socket will make it easy to replace a defective relay. The relay can not be damaged by heat from soldering if it is plugged into a socket. Sometimes troubleshooting is made easier by unplugging a component from a socket. But I prefer to solder parts directly to a PC board without using a socket, especially if subject to harsh environmental conditions. Then I do not have to worry about a bad connection between the part and the socket.

While not suitable for complex circuits, simple circuits can be crafted by adding jumpers to the component side of the board.

Another option is purchase of wire wrap DIP IC sockets, then cut pins off the sockets to obtain single pins.
