How to connect a dual coil relay ?

Postby stregoi » Fri Jun 13, 2014 12:18 am

Hi, i am a very beginner in electronics, i am trying to make this circuit below. So when i push the first pushbutton, the motor should turn, and when i push the second push button the motor should turn in reverse.
as i can see from the schematics, they used a single coil DPDT, with 8 poles ( i think ) ... but i have a dual coil DPDT, with 10 poles ( TQ2-2L-5V ).
how can i use my DPDT relay instead of the one shown in the schmatics, i tried really, i cannot figure it out.
thanks

It looks like the motor will run forwards as long as you hold in the button, and to reverse you have to hold in both buttons.
Is that what you want?

Yes, you can use a dual coil. How it is wired depends on the motor. How much current does the motor take?

I am using 5v for the motor, the relay tales 5v as well

I can see it uses 5V.
I was asking whether it is a small power or large power motor. Like how much current it takes (how many amps or milliamps)?
