It should at least be shielded (so no<br> cheap switch boxes from Amazon adorned with Brother P-Touch labels,<br> those are also manual push buttons :) ).<br><br> Some of the closest I've gotten are A/B switches but they're in desktop<br> cases and are just too big.<br><br> Purpose:<br> I am going to be installing a VoIP door station to replace the doorbell<br> button. It's a PoE unit so I do need all the pairs. It has several<br> additional I/O and power ports for various uses, one of which provides a<br> steady 12 VDC when the unit is up. I plan to link this to a latching<br> relay in such a way that if the 12 VDC suddenly disappears (e.g. someone<br> took a baseball bat and adjusted the camera angle), it will break the<br> Ethernet lines to the exposed patch cable making it a dead cable which a<br> computer can't use.<br><br> The box itself doesn't need the latching relay, it just needs a simple<br> relay that is either on or off with the application of signal. I'll<br> take care of the latching part separately with other external relays.<br><br> I just can't seem to find anything like this. Just for fun I tried an<br> industrial PoE injector that I had handy which takes 24 VDC in but the<br> data lines are passed right through the unit so even with it off it<br> doesn't stop the drop from working as a minimum 10/100 (two pair) port.<hr> Ale mailing list<br> Ale@ale.org<br> <a href="https://mail.ale.org/mailman/listinfo/ale">https://mail.ale.org/mailman/listinfo/ale</a><br> See JOBS, ANNOUNCE and SCHOOLS lists at<br> <a href="http://mail.ale.org/mailman/listinfo">http://mail.ale.org/mailman/listinfo</a><br><br></blockquote><hr> Ale mailing list<br> Ale@ale.org<br> <a href="https://mail.ale.org/mailman/listinfo/ale">https://mail.ale.org/mailman/listinfo/ale</a><br> See JOBS, ANNOUNCE and SCHOOLS lists at<br> <a href="http://mail.ale.org/mailman/listinfo">http://mail.ale.org/mailman/listinfo</a><br></blockquote><hr>Ale mailing list<br>Ale@ale.org<br><a href="https://mail.ale.org/mailman/listinfo/ale">https://mail.ale.org/mailman/listinfo/ale</a><br>See JOBS, ANNOUNCE and SCHOOLS lists at<br><a href="http://mail.ale.org/mailman/listinfo">http://mail.ale.org/mailman/listinfo</a><br><br></blockquote><hr>Ale mailing list<br>Ale@ale.org<br><a href="https://mail.ale.org/mailman/listinfo/ale">https://mail.ale.org/mailman/listinfo/ale</a><br>See JOBS, ANNOUNCE and SCHOOLS lists at<br><a href="http://mail.ale.org/mailman/listinfo">http://mail.ale.org/mailman/listinfo</a><br></pre></blockquote></div><br>-- <br>Computers amplify human error<br>Super computers are really cool</body></html>
