I bought these keys from Abu 12 Fish Bucket, in Yemen, we said we are trying to make Emirates, and after installing some of them, the key broke after months. It broke from the inside..and it remains either on, stopped or completely idle.The disadvantage of these chips is not only the switches, but the place where the wire is attached. The hole is small, and it is not possible to put a wide wire into it.I have English-made keys and chips, now 17 years old, and maybe another 17 years left.Oh God, it does not exist in our town, and we need to buy it in big cities.I hope the plug switch will be redesigned, so that it will not break from multiple use, and the wire hole is made larger.I bought 1 dozen of these sockets in Yemen.We tried UAE made stuff.After we installed some of them, switch broke down after several months. It make the socket either on or off or not working at all.!Shortcomings of these sockets not just the switch, but the wire opening behind it, it is small not enough for big wire.We have British made sockets that have been used for 17 years, and may last 17 more years. Just we can not buy them from the area where I live.We need to buy it from big cities.I wish you redesign the socket switch, so it won’t break quickly, after using it several times, and make it fit for big wire.
