Finally something i know about
ip ratings are split into two sections the first number then the second. First number designates the protection against solids, the second the protection against liquid ingress.
First number 6 means that the unit is totally sealed against dust, it'll go as low as 0 which is no protection. Second number 5 is protection against low pressure jets of water from all directions, 6 is protected from high pressure jets of water from all directions with limited ingress allowed (at high pressures).
The ip65 switch should do the job, but i'd go for the ip66 one, just cos it will be definitely protected against any water ingress that you could encounter on a bike.
If you want to get really serious ip68 is the way to go, protected from long periods underwater at pressure![]()

Mind you probably unnecessary to fit IP68 to a 1200as the fuel pump wotsit is about IP10!!! 




Still not further on.The ip65 switch should do the job, but i'd go for the ip66 one
I'm planning to fit some lights to the bike and was wondering about the switch. Will an IP65 rated one be sufficient or should I be looking for IP66?
Any suggestions gratefully received.![]()
Or is it that I have no idea what I've been doing for the last thirty years?



After a year of being used every day it still works fine, although I have had to replace the velcro!


Hi Val
I don’t know what IP rating the standard switches have. That’s partly why I thought I’d ask for some help on here.
I’m not sure that it’s as simple as saying that a switch is or is not waterproof. The IP numbers are ratings of protection.
RC Mad seemed to understand what I was getting at- 65 possibly good for the job, 66 even better, which was exactly the conclusion I had come to.
“Why is it that people out there are taken in by the 'waterproof 12 volt switch myth' ?????????”
I don’t believe I have been taken in. Are you suggesting that an IP66 rated switch offers no more protection against water than a non-rated switch? It just seemed a sensible precaution. I’m not sure who you’re referring to when you mention “companies claiming that we should need waterproof switches”. It seems fair enough to me that manufacturers make switches with different levels of protection to suit the needs to which they might be put. I currently have a rocker switch which I bought from R.S. and it has an IP65 rating and wondered if I should really have an IP66 one. I was just looking for some advice. Thanks for the input though.![]()
