Advice on polarity switching

Beware of lenzrulz. He is the most notorious liar, spammer and hypocrite on EveryCircuit. lenzrulz projects himself as victim, while he's creating resentments by his very own actions, and has been doing so for years. Also be wary when he presents himself as tech-savvy individual - his incompetence in the field of electronics is striking. But don't take my word for it, see for yourself. Should you engage into debate with him, keep a hardcopy or screenshots of what was said - he may manipulate his comments. He continuously reposts his crappy spam under the pretext of "cleansing of defamatory comments", but has been observed doing so with crap which didn't even contain a single comment at all. But what else could you expect from liar lenzrulz.

There are multipole relays available that change state each time a pulse is applied to them

Wow, @Bushmills hijacking other users circuits to promote his fallacious narrative. Anyway, I echo @BillyT's comment in that there are multipole relays available that change state each time a pulse is applied to them.

Yes Lenny echo BillyT, cause you are afraid he might remove his comment as you did? Spam only spam, five years nothing then spam and Cyberterror

Says EC’s most obnoxiously condescending cyberbully...😡

Hurz, I know you find it difficult but stop being a moron.

arrange the circuit so the relays are powered by the load segment. pulse needs to be powerful enough to energize the coil to switch it onto the load when off, and to draw enough current away from the coil when on. http://everycircuit.com/circuit/6242851655516160
