Carbon copy of what I have been making and selling for about 10 years. Problem is the ease at which on of those switches can be flipped off well that and those are not waterproof. That is why I always used the locking switches as they can't be bumped off and they have a special washer fused to the switch body that captured a oring for a water tight seal and the switch itself has a double sealed stem to keep water out. If the water isn't sealed out of the switch it isn't going to last very long and can leak through. NKK discontinued the locking switches. Made the whole idea pretty worthless without the waterproof locking switches.
I am working on something now that is going to be way more bulletproof and dependable than the locking switches were. The last batch I got from NKK was a bum batch. Odd since I had never had a single bad one prior to switches becoming obsolete.
