Can it be used for mechanical switchs on keyboard

On a mechanical keyboard, you would only want to use this on the stabilizers where the metal bars come into contact with the housing. As for the switches themselves, you would want to use a much thinner lubricant. Suggestions are below: Linear - Krytox 205g0 is a thicker lubricant that can help linears feel super smooth. Tactile - Tribosys 3203 is thinner and provides good performance. Avoid lubing the legs, as these are responsible for the "bump" in tactile switches. Clicky - Although you can lube clicky switches, nearly everyone recommends not doing so, as there is a high chance of losing some of what makes a clicky switch appealing to those who enjoy it.

How many uses do you get out if this tube?

Depends on how it is used and for what. It will obviously last longer when used on small jobs vs. big jobs.

Is it a good product to use on ordinary home inside or flood lightbulbs? thanks

Absolutely, it will keep bulbs from freezing into the sockets, it keeps oxidation out of any connections.

Can this be used with rubber O rings on flashlight?

I am sure that it would not harm the o ring if you use it.

カプラーに。

ヘッドライト(H4)のカプラーに塗りたくってます。カプラーの焼け焦げが無くなった気がします。湿気やホコリから守ってくれてるのかも。
