Be careful with switch ratings Noelia as an AC rating is a lot different to a DC rating (much less capacity for DC particularly switching an inductive load (ie horn, coils etc). also bulbs (not LEDs though) have a massive inrush current from cold as they are low resistance when cold and increase as the filament gets white hot. You could use those switches fine but with automotive relays doing the main current switching.These look cheap and OK on DC current.http://www.ebay.co.uk/itm/5pcs-40A-12V-Car-Bike-5-Pin-Changeover-Relay-Switch-L4/391361666019?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140122125356%26meid%3D88ade15a7dba4195827fece27cc670cf%26pid%3D100005%26rk%3D5%26rkt%3D6%26sd%3D172054228471I am too far away to help but we should be able to sort you out anyway.Basically you need to connect 86 (coil) to an earth and switch the other coil connection (85) with the little switches. You then use terminals 87 and 30 to replace the contacts on the old switches. I would need to look at the actual switching arrangement on the 500/550 to work out the relay combination you require
Such tiny switches call for an m-unit:http://motogadget.com/en/electrics/electronic-control-box-m-unit/m-unit/m-unit-digit-tastersteuerung-u-sicherung.htmlSaves one having to set up an array of conventional relays...
The toggle would need to have two relays with the input power to the common and selected powers going to relay
...for example high and low beam.
Hi where did you get your switch from?
