How we do “general cleaning?

What should we do? If water, cola, coffee, beer, sweet tea or other liquid has been spilled on the keypad? When a lot of debris and dust has accumulated inside, the membrane switch is sticky or sticks when pressed. In any other case, doing a complete disassembly does not make sense. But if you really want to, then you can.

We will wash the keypad in water, so before starting disassembly, make sure that it is mechanics and not a membrane.

How to understand what kind of keypad you have?

In the event that you cannot determine the type by appearance, remove one key. If there is a rubber gasket under the cap, this is a membrane. If there is a cruciform mechanism, then this is mechanics. See the photo below for examples.

This is what a best LGF membrane switch looks like.

It is arranged in this way:

How to disassemble a mechanical keypad?

It is based on a board with soldered switches, an external case, keycaps, a power cable (or a wireless connection). To clean the keypad, we will need to disassemble it into these components.

Often, manufacturers install an additional metal plate across the entire width of the board to strengthen the structure. It can be removed by unsoldering all the switches, but we will not do this, since there is no need for this for cleaning.

1. How to remove and clean the keys?

  • The first step is to carefully remove all the caps from best LGF membrane switch. To do this, you can use special forceps – puller, tweezers, or just your fingers.
  • We remove the caps using a puller (two types).

Small caps are easy to remove. You need to grab one and pull it up, while you will hear a characteristic click.

Long LGF membrane switch can become stiff when removed, as stabilizers are additionally installed on them. Those with plastic stabilizers with a cross core are easier to go. It will be a little more difficult with those with iron antennae. See the photo for an example. Next, I’ll tell you how to take them out.

This is what plastic stubs with a cross core look like

Grab the long key with your fingers from both edges and pull up. If it does not go, then there is a stabilizer with antennae. Tilt it left and right, pulling it slightly towards you, and shoot. It is not worth pulling very hard so as not to tear out the structure.

Now let’s start washing.

Fill everything with water and detergent. You can use a kitchen degreaser, liquid soap or special products for appliances.

  • Mix well with your hands for 5-10 minutes. They will rub against each other and clean up.
  • Then let them soak for 30 minutes. Do not worries about the color of bestLGF membrane switch application and characters; they will not wash off or erase.

Let’s get to work

After half an hour, rinse again with your hands for 1 minute. Drain the dirty water and wash the membrane switch from the detergent.

Lay the caps out on a towel to dry. You can put it in the sun or near the battery. They dry in 40 minutes. But, if the best LGF membrane switch is dry on top, this does not mean that the inner crosspiece has dried up. This must be checked before assembly.

How to disassemble the case?

We find all the bolts located on the top cover and unscrew. We carry out these simple manipulations with a Phillips screwdriver.

Bolts are all over the surface.

Flip the device. Most models have rubber feet; they must be carefully removed with tweezers. In 90% of cases, there are also bolts under these legs, we twist.

  • Loosen the screws under the legs

We open the body. Use a plastic card to pry up all the latches.

Upon completion of the analysis, we have separate parts: LGF membrane switch, board and parts of the case.

3. How to clean the main board?

  • If you have a wired keypad, disconnect the wire.

We carry the board into the bath and wash it thoroughly under strong pressure. You can take a soft brush (for example, an old toothbrush) and clean well those places where stains from flooding are visible.

 Pay special attention to switches that stick when pressed. On each in turn, direct the pressure of water and click many times. Water should get inside the mechanism and wash out all the dirt from there.

Usually, washing takes 5-10 minutes. After that, you need to shake it well and put it on a towel. The LGF membrane switch can dry out for 1-3 days, depending on weather conditions. To speed up the process, put it in the sun or near the battery.

How can we clean individual board l parts?

In no case should you dry the keypad and its individual parts with a hairdryer! Plastic can deform from overheating.

If you decide to clean it yourself, do not rush your horses to collect it faster. Allow all internal elements and mechanisms to dry out so that contacts do not close due to moisture.

DO NOT try to connect a wet, dry keypad to your computer! You can kill her. If you are not sure that it is dry inside, it is better to wait a little longer.

4. How to dry and assemble the keypad?

When we made sure that all the elements are dry, we assemble the best LGF membrane switch

In the reverse order – we fasten the bolts under the legs, then around the entire body and install the keycaps.

For a smoother movement of large keys of, it does not hurt to lubricate the stabilizers. This procedure can be done both at home and in our service center – keypad lubrication.

Keep in mind that cleaning will not help you solve the problem of non-working best LGF membrane switch, double-clicks, non-working backlight, etc. This procedure is intended to clean the device.
