Where to find a 6V 5 prong relay?

[Bugman Jeff]

I'm looking for an automotive style relay. The problem is I need a 6V relay. I'm looking for one like the standard black 5 terminal(85, 86, 30, 87, 87A), only in 6V. A 4 terminal relay won't work for what I need. Anyone know where I can find such a thing? Thanks.

maybe this? what do you think? -

Provided it's got the same operating schematic as a standard automotive relay it might work. 'Spose it would last on 7V(nominal voltage of a 6V car)?

The problem is I need to open one circuit while closing another, thats why I need the 5 prong relay instead of a 4 prong.

there's one relay that works 7vdc and another one that works on 6vdc. i am looking for a relay to connect in place of a servo motor to use a servo as a power switch. i am confused which relay to buy too.

Hi, You could try using a 5V relay (more available than 6V) and put a small resistor in series with the coil to drop the extra volt.
Some relays won't even need the resistor since they can take a "range" at the coil input.
Just measure the current that the coil uses on 5V and then divide 1V (6V-5V) by the current measured and that would give you the required resistor value (in Ohms if you used Volts / Amps).
Hope this helps.
I can't remember the name of the company in the US, in UK they are called RS electronics or Farnell Electronics. They have a range of relays for 5V coils.
Can't give you a part number because you have not specified the current/voltage required on the contacts.
Cheers

It would help for selection if the requirements were more specific? DPDT, SPDT, SPDT, make before break, current capacity required, etc.

:D :o :confused:

i know.. its 20$, and far from DIY, but i love the simple awnsers. especially if me pointing this out to you actually solves your problem :)

Thanks, the carry current from an electric airsoft gun fried my $3 relay, so I might have to go with 10A battle switch after all.. :(

either that, or use a servo to push a button to fire :P

NOOOOOOOO! I'll have to see if the 10Amp relay will survive the job, before I give up and use a servo to push a button to fire.

it should do more than fine.

Max relay current: 10A @ 28VDC, 12A @ 120VAC, 10A @ 240VAC.

Just checked the maximum required current and 10A will do the job by far. The electric airsoft gun takes 3.5 Amps, which explains why my 2A relay burned out. I've ordered a 10A relay and can't wait till it arrives.
