میکرو سوئیچ 3 پین مناسب Mouse مدل  (10M) D2FC-F-7N بسته 2تایی

میکروسوییچ گونه‌ای از کلید است که با فشار فیزیکی بسیار کوچکی تحریک می‌شود. عمل کلیدزنی در وضعیت‌های مشخصی از محرک اتفاق می‌افتد. استفاده از میکروسوییچ‌ها به علت هزینه پایینشان و عمر مفید بالا بسیار رایج است. فرق میکروسوئیچ با کلیدهای قطع و وصل عادی این است که شاسی میکروسوئیچ به صورت فنری می‏ باشد، یعنی تا زمانی که روی آن فشار اعمال می‏شود، جریان برق را قطع یا وصل نگه می‏دارد و در لحظه رها شدن شاسی، وضعیت به حالت اولیه خود برخواهد گشت.
میکروسوئیچ‏ها معمولاً دارای سه عدد پایه می‏ باشند. یکی از پایه ‏های میکروسوئیچ معمولاً با COM مشخص می‏ شود که پایه ورودی آن می‏ باشد. یکی از پایه ‏های آن با علامت (NC (normally close و پایه دیگر با علامت (normally NO ( normally open مشخص می ‏گردد.

Description:
A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism.
Switching happens reliably at specific and repeatable positions of the actuator, which is not necessarily true of other mechanisms. They are very common due to their low cost but high durability, greater than 1 million cycles, and up to 10 million cycles for heavy-duty models. This durability is a natural consequence of the design.
The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Most successful designs also exhibit hysteresis, meaning that a small reversal of the actuator is insufficient to reverse the contacts; there must be a significant movement in the opposite direction. Both of these characteristics help to achieve a clean and reliable interruption to the switched circuit.

Microswitches have two main areas of application:
Firstly they are used when a low operating force with a clearly defined action is needed.
Secondly, they are used when long-term reliability is needed. This is a result of the internal mechanism and the independence of the closing force on the switch contacts from the operating force. Switch reliability is largely a question of the contact force: a force which is reliably adequate, but never excessive, encourages long life.

Features:
Omron D2FC-F-7N microswitch (10 M)
Life 10 million times life! It is twice as much D2FC-F-7N!
It can be commonly used as long as your mouse has been used as a three-pin rectangular microswitch.
Most of Logitech's original mice are this micro-motion, such as MX518 MX510 G400 G500 G5 G7 G9X and so on.
