I need a recommendation for a relay. My timer outputs +5vdc for 30ms when the timer goes off. I need a relay that will switch a 12vdc circuit on during the 30 ms output. The amount of current in the 12vdc circuit is small (milliamps). I've been using a Radio Shack reed relay, but I'm having problems with reliability. Here is a link to what I'm using today:
My application requires some fairly rough handling and I think this is what is causing them to fail. Any suggestions on a solid state relay? Ideally, it would be small and easy to get at a Radio Shack or other retail electronics shop. The relay needs to be normally open. I've looked at some photo-MOS relays but they are not easy to find.
Any suggestions would be appreciated.
