« on: October 12, 2009, 08:46:09 PM »
Hi, its me yet :)

To turn off/on my trike I need a keyswitch 30-40A 36V. (on th

I found keyswitchs but not 30A keyswitchs.

Do you know where I can find it ?

Thanks you

Greg,

I know it's not very small or attractive, but something like this battery isolator switch would do the job:


     Click for further details    


Don't worry about the stated 24V max, this switch can handle 1200 Watts continuous and will work fine on your trike.

Most car accessory shops will sell them.

An alternative is to use a low power key switch with three 12v 15Amp relays.
Their coils wired in series for 36V operation and the switch contacts wired in parallel for 45Amp switching.
Approx 100mA power consumption (3.6Watt for all three relays)

Hi Bikemad and all  :)

Thanks you for answer, it's posssible I use your alternative.
I have found a keyswitch 40A on a web site (ref X-KS-01) but there is no photo of product. I 'm waiting for answer from seller.
Maybe it's the same product of you tell me ...

But this keyswitch is key useless, someone can turn power on with a screwdriver  ;D maybe I will put a button...

Bye
