Start / Stop button.

[Mat Jackson]

OK,

I know loads of people have fitted start buttons, but has anyone fitted a start / stop button?  IE press to start and then press to stop.

I know Caterham have these fitted on the R300 et al, but not sure how they work.  Anyone any thoughts?

I don't know if the start stop button is part of the system, but Caterham use a control module for their Savage style switchgear on the R models. It adds the operating logic to the simple press once type buttons. So press once for wipers at slow speed, press again for fast speed, press again to turn off etc.

Caterham's module isn't perhaps the best of designs - I believe all the relays etc are potted, so if one fails the whole module is capput. It's also quite expensive.

Some similar type control boxes are starting to appear on the market, I know these guys were working on one Clicky

Surely if going to the trouble of making up an electronic control module then one would replace electro-mechanical devices such as relays and replace with solid state logic which are a lot smaller, more reliable and less power.

2 editions back in Westfield World this was covered. where a start button was fitted with aircraft style flip down stop. Does that work for you?

Maybe, maybe not. Automotive use still seems to be clinging to a mix of conventional "automotive" relays alongside Canbus localised processing networks, even at a main manufacturer level.

If you insist on doing it the geeky way     Motec will sell you a dash/ecu/logger etc package that includes power control/distribution modules that replace conventional relays. Some serious cost involved though...

Interestingly Race Technologies DL1 mk3 data logger looks like it's moving somewhat down the control of other devices route. Though AFAIK they haven't actually addressed the switching of high current loads as yet.

Opto couplers/Isolators are not expensive. Are the lights in modern cars controlled purely by a module. I am sure my tin top has only two sub miniture relays.

Motec PDM15 will handle this and all the rest of the relays, fuses and everything.

It can be done with a couple of relays, depending on exactly how you want to do it b - do you mean button for "IGN on" etc, then "start" ( starter motor) button and an off button to kill the engine?

To latch a relay in from pressing the IGN on button ( noramlly open  non latching) you simply put a relay contact across the button - so pressing the button powers the relay coil and the contact "seals" it in.

To STOP you just need  a Normally closed push non latching button in series with the relay coil.

You might need to put two relays in parallel so you have a spare contact set to power your ign circuits  ( relay B) etc.

Please Miss, can I be excused? My brain is full.

There are fully programmable solid state control systems available for vehicle converters which would work very well in a westy.....only problem is the cost....

Yes I've done it on mine, using a single push button switch, 1 latching relay and a 2 second time delay relay to crank the starter if the button is held for more than 2 seconds.

So 1 press of the button for less than 2 seconds just turns on the ignition, a second press turns it off. But if you press and hold the button for longer than 2 seconds the starter will crank until you release the button. Then another quick press will turn it off.

Mine also has an RFID smart relay I bought in the States which only activates the ignition if the key fob is within range. Means I don't have a seperate ignition key switch as well, just the single button which is only active with the key fob in my pocket.

very idea Mr Blue  like this, I guess smartkey and latching relay like this . I've not come across those before - its a dip/main beam relay - could have loads of uses..

I think £4.34 should do mine  ...    fleebay

say what? can you put up a diagram and whats a rfid thingymabobby
