Project Description

KEYPAD

Silicone Rubber keypads are used extensively in both consumer and industrial electronic products as a low cost and reliable switching solution. The technology used the compression molding properties of silicone rubber to create keywall around key switch.

Experience

With our core expertise in designing, engineering and producing from simple to complex keypads, we are involved at every stage of the manufacturing process, from the initial design to full implementation.

Application

The conductive resistance of silicone rubber keypads have very obvious different requirements in different application scenarios. Gold conductive pill is widely used in the automotive controller.

Service

We specialize in producing custom-made products, ensuring the most accurate, timely and cost-effective design and manufacturing process to meet your every need.

CONDUCTIVE CONTACT

The conductive resistance of silicone rubber keypads have very obvious different requirements in different application scenarios. Gold conductive pill is widely used in the automotive controller.

Gold-plated surface conductive capability is strong, the magnetic resistance is strong, manufacturing key switch does not affect the stroke curve and reverse.

  • Longer lifespan
  • Suitable for automotive keypad that need to withstand higher current and voltage.
  • Can satisfy normally 1000MA large current work load, good durability.
  •  Can work in extreme circumstances (85 ℃ to 40 ℃ + / 90% RH)
  • Resist oxidation and SGS qualified.

Conductive pill is the contact medium between the silicone keypad and PCB board. The mixture is molded on sheet form and the round pills are the common shape in standard sizes between 2mm to 8mm diameter. A jig is used to insert the pill onto the keypad.

The most commonly used for silicone rubber is the carbon type pill which the resistance normally is around 200 Ohm with 100 grams loading. For the products requiring the lower resistance, Metal and Gold Conductive Pill are available.

Carbon Conductive Printing is also the contact medium between the silicone keypad and PCB board, using the conductive ink. This can be applied to any shape of carbon contact, say round, square, oval, etc. For product resistance requirement, the resistance will be ranged from 500 ohm to 800 ohm.

Application Examples

  • Inner Silicone Rubber keypad for Steering Switch (in-car Use)

  • Inner Silicone Rubber keypad for Audio Switch (in-car Use)

  • Inner Silicone Rubber keypad for Power Window Switch (in-car)

  • Customer’s Silicone Rubber keypad

QUALITY GUARANTEE

Gooodol’s quality ratings are sustained through the implementation of a rigorous quality control system. Part quality is carefully verified through in-process inspection plans where parts are constantly monitored for defects, damage, or any other inconsistencies. A database control number that calls down to the material batch used to produce the part is assigned and recorded for every part made. Every product packaged can then be traced back to the date the part was produced, the processes performed, and the materials employed.
