Mouse button clicks

Greetings all.

How many times does the left mouse button get clicked during the lifespan (projected, i guess) of a computer mouse?

(I would imagine companies that produce these items must have some idea of this…)

Thanks in advance

The switches in a typical mouse button are rated for somewhere around a million clicks. A cheapie mouse will be less than that. A mouse specifically advertised for gaming might have a rating more in the 10 million to 50 million click range.

That rating is just for the switch. Environmental factors like dust, cigarette smoke and ashes, animal hair, etc. might cause the mouse to get clogged up and stop working long before the switch actually breaks.

I used to replace the microswitches in Apple’s original mouse, because people would wear them out.

jeez 50 million clicks. :cool: how on earth would they calculate that?

cheers guys

Do they make the left click button more robust, because they expect it to be used more?

I mouse left handed, so the right click button on my mouse gets more usage than the left click button.

I use a Logitech trackball mouse ( and after a while, the left button does indeed quit working reliably - most commonly, it will register a double click when a single one was intended. I’ve learned that I can use the mouse’s software to switch the buttons… and my brain switches between the two configurations relatively quickly. They still only last about 2 years. I don’t know if that’s a typical lifespan for a 1-million-click mouse or not.

“Funny” stuff with mouse buttons happens to me often enough.

I just unplug it, open it up, clean it out and put it back together. I can make a mouse last 10 years or more.

[/quote]Wow. People used to repair their mouse rather than just throw it away and get a new one? :open_mouth:

Oh, yes.
Back when the Macintosh was introduced, Mice were rare and valuable. You couldn’t just go to Best Buy (or Radio Shack) and buy one, and there was no Amazon. So, spending $2.00 on a new microswitch, 15 minutes of time, and a bit of soldering skills was well worth it.

I recently replaced my Logitech mouse when I could no longer reliably click-and-drag with the left button; I kept dropping items in the wrong spot. I think it lasted about ten years, but not really sure.

Interestingly, there was some metal trim on it where the skin between my thumb and index finger rested; the metal was multi-layered, and over the years my sweat had corroded away the upper layers of metal.

“Used to”? Good mice are expensive, often >$100. I’ve never had to perform a physical repair but I’ve disassembled and cleaned my mice multiple times. 20 minutes to salvage a $100 mouse is certainly worth it to me. Even more so if it’s a model that you like but was discontinued.

Unfortunately, my experience is that the rubbery bits will start melting before the microswitches, etc. go bad. And at that point there really isn’t anything to be done besides tossing it.

Jesus, you’re melting your mouse? I guess you guys are just more extreme users than I am. I don’t even overclock my CPU, and here you guys are worried about heat management for your mice! That’s another level.

I suppose I could buy a model with a little fan attached:


You didn’t follow the memo about mouse balls?
Re: Replacement of Mouse Balls.
If a mouse fails to operate or should it perform erratically, it may need a ball replacement. Mouse balls are now available as FRU (Field Replacement Units). Because of the delicate nature of this procedure, replacement of mouse balls should only be attempted by properly trained personnel.
Before proceeding, determine the type of mouse balls by examining the underside of the mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ depending upon the manufacturer of the mouse. Foreign balls can be replaced using the pop off method. Domestic balls are replaced by using the twist off method. Mouse balls are not usually static sensitive. However, excessive handling can result in sudden discharge. Upon completion of ball replacement, the mouse may be used immediately.
It is recommended that each person have a pair of spare balls for maintaining optimum customer satisfaction. Any customer missing his balls should contact the local personnel in charge of removing and replacing these necessary items.
Please keep in mind that a customer without properly working balls is an unhappy customer.
