relay help

i have a relay and when the ignition is switched on i get a positive pulse for one second but i need it to be five seconds or maybe ten to be safe. any help i was thinking about capacitors but i highly doubt they would be charged in one second correct me if i am wrong

Pulse Timer with Spdt Relay. i use one and it works perfectly up to 90 sec delay to turn on or off.

well u can try a timer relay that will remain latched for the specified time..but i don't know what's ur application...

application for mirrors to fold in and out Strugglerzinc, would this work.
eitech, could suggest something cheaper?

Strugglerzinc · Posted: Fri Nov 20, 2009 7:48 pm Post subject:

if its for mirrors, afaik they don't work with a pulse. the fold in/out uses 2 or 3 wires and it switches itself off when it reaches final position in either direction regardless of if the power remains applied hence why most are controlled by a simple DPDT switch.

Strugglerzinc, yup exactly thats y i need a five sec pulse. it works with three wires one ground one + and one -.

u sure five seconds is the amount of time you need?

I dont think the fold in mirrors work on a pulse.
I've never torn one apart but I would think they work on triggers to tell it when it stop.
You said it had three wires?
I'd go on a limb and bet the ground wire is the trigger to stop it from folding
While the other two wires reverse polarity to control open/close

yup dat sounds like it..jus like d windows up module..when u arm ur alarm, it uses a negative trigger from d alarm to tell d windows module to close

DPDT relay controlled by ignition can work if you want it to automatically open and close with ignition

Strugglerzinc, where to buy one of these?

Strugglerzinc · Posted: Sat Nov 21, 2009 2:49 pm Post subject:

that i cannot say....sorry. I do most of my electronic shopping online.

but wouldnt this drain the battery? thats why i wanted one for abt a five second pulse
pulse timer from above would work?

i've hooked up folding mirrors to my ke70 but i use a control switch and 2 five pin relays.....i have the diagram somewhere......

hey take a look at the 555 ic aka the
[ time machine] http://www.kpsec.freeuk.com/555timer.htm
you can do anything with this
i can draw a circuit for what u want to do but thats some headache this hour
give me some time...lol

it so versatile you can set up circuits so it closes in the night and opens in the morning
no draining current ......but thats for crazy guys like me

oh it costs six dollars by steves Very Happy

u don't have to go through all that commotion pallie.

when my car starts,the mirrors open and when it cuts off the mirrors fold in.no switches.

all that was used was 2 relay found at any parts shop.

if u want i can link u up.$250 supply and install and bogoon,ur mirrors foldin and openin with ur ignition.

holla at a brother if interested!
