I would like to maintain the two panel mounted SPST switches from the previous installation but to operate the wigwag circuit and switch all three to constant "on", one of the switches has to be a DPDT. Theoretically, I could power a DPDT relay from the SPST switch but searching Mouser and Digikey I am finding a dearth of possible candidates. Another option would be to use two SPST relays of which there are plenty and operate them both simultaneously via the panel switch. I would appreciate advice on the variables for the contact materials, coil resistance, etc. for this application.

Hi Bob, Indeed, a potted version of the device so no salvageable knowledge there! Appreciate the feedback; this is one for the bin!

Mouser #:769-ACTL3CR3V Silver Alloy contacts are good for power applications. Gold contacts are for small signals, not power. Coil resistance should be greater than 100 ohms. Otherwise the relay will get too hot. Here is a DPDT from Digikey. Part number: A102CS12VDC Looks like both relays above have pins that require soldering. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502658#502658 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
