Technical parameters of membrane switch

Membrane Switch is a type of switch based on diaphragm, conductive material and bonding technology, which has the advantages of small size, light weight and high reliability. Commonly used in electronic products and instruments and other fields of control panel.

1. Trigger force

Trigger force refers to the force required to press the membrane switch , generally in grams (g) or N (N) as a unit. The size of the trigger force has a certain impact on the operator's hand feel and switch life, so it is necessary to choose the appropriate trigger force according to the actual situation.

2. Life span

The life of the membrane switch  refers to the number of keys it can withstand or the time of use. Life is related to manufacturing process, material selection, mechanical design and so on. Normally, the life of the membrane switch  can reach more than one million times.

3. Impedance

The impedance of the membrane switch  is usually expressed in ohms (Ω), which refers to the difference between the switch's return to zero resistance and the on-off resistance value. The impedance is directly related to the reliability and anti-interference ability of the switch, and the general requirements are small.

Step 4: Size

The size of the membrane switch  is generally customized according to user needs, including thickness, length and width, aperture and so on. Due to the small space required by the membrane switch , the space of the entire switching system is greatly saved, so it has an irreplaceable role in some applications.

5. Whether it is waterproof

The waterproof performance of the membrane switch  refers to whether it can work properly when it encounters water or other liquids. Some membrane switch  need to be waterproof to ensure the normal use of the equipment.

Thin membrane switch  has the advantages of small size, light weight, high reliability and low cost, and has been widely used in modern electronic products and instruments. membrane switch  with different technical parameters can be selected for different use environments and requirements.
