    I bought a nice little 12 volt RF transmitter/receiver package not realising the DIP is latching. The momentary DIP is PT2272M4, made by Princeton electronics. There are a bazillion in the hands of big distributors, I found at retail one in England, one on ebay where I don't do business. Does anyone know where I can find this, an equivalant, or an inexpensive 12 volt RF transmitter/receiver with relay for momentary contact use? For up to 100' max type use out of an automobile.

    Is that a relay in a DIP (Dual Inline Package)? If so, do you know the pinout? Are pins 3-4-5 & 10-11-12 missing, power applies to pins 2 & 6, 14 makes to 7 & 8 when energized?

    Way more to it than just a relay. What is the application?

    I have the complete unit. It works fine, I just want to change it from latching to momentary contact. The PT2272 M4 is the Momentary contact DIP.
