solid state relay problem

[filjoa]

hi

I buy this relay https://www.futurlec.com/Relays/SSR3A12V.shtml

but now I don't say work with them...

for example, when I buy this relay my ideia is for have 2 positions when I put a power signal on relay it go to position 2, after I turnoff the signal and ir stay on position 1, but when I put again power signal it go to position 1...

with this relay witch I buy I put power on pins 5 and 4 and with multimmeter I have some connection in pins 1 and 2 but if I turnoff power and after put again I have the same results.. (multimmeter have some connection in pins 1 and 2)...

some one can tell me how I can mount this relay for it work?

kind regards

The said relay is designated SPST (single pole single throw), I guess, it does just this (no double throw, no latching). What are you searching for?

I looking for an relay like flip-flop...

one pulse stay on, oder pulse stay off, oder pulse stay on,....

but if power turnoff stage don´t change, stage only can change when I give the pulse...

Yes, the present relay isn't. I don't think, that any solid state relay with similar behaviour exists. It would need a permanent power supply for the state memory. I'm only aware of mechanical bistable and impulse switches.

 

[filjoa]

but you know any mechanical relay reference? on ebay or farnell? for example...

 

[FvM]

E.g. Farnell 9515585 (from dold.com) or the traditional impulse switches from eltako.com, used in home light control.

thanks FvM

this item work as a flip-flop like I need?

Yes, there is a diagram for the Dold bistable relay, showing the contact position resulting from coil drive waveform.
