Long stroke solution– Silicone Keypad

Long stroke solution– Silicone Keypad.

A Silicone keypad is designed to provide electrical contact and tactile feedback. The tactile feedback indicates and confirms that an electrical contact has been established.

The haptic or the tactile feel is influenced by three factors:

• Force
• Stroke
• Snap

Abatek controls the above three elements by influencing the membrane geometry. 
The total assembly and actuators have significant impact on the haptic.
To fully control all those elements it is necessary to run an own high precision tool making shop and production.

Huge experience in the keypad industry has over many years resulted in exciting solutions and great customer relationships. Mastering all aspects reflecting the desired force/way specification AND controlling the crucial assembly makes Abatek THE partner of absolute trust.

Short Stroke – ClickPad

THE short stroke solution.

The Abatek short stroke solution “ClickPad” replaces traditional micro switches.

The Abatek ClickPad system is an unique integration of the optimal metal dome into the keypad.

It offers the world’s best solution in terms of force, snap, acoustics, life cycle, preload, lighting, sealing, price etc.

In assembly the ClickPad can achieve a stroke between 0,4 – 2,0 mm and is characterized by a distinctive snap feel at the peak force despite the short stroke.
Additionally it gives you the option to adjust the sound without losing the sharp tactile feel. 

Special short and long stroke solutions

Abatek offers many different options and combinations for various force/way curves.

In addition to the two above mentioned and mostly used stroke solutions, we also offer various other special solutions.

The most common ones are:

• Double stroke
• Redundant
• Early contact
• Over stroke
• High force/Snap/Life cycle

This is just a selection from our program. Contact our technicale sales team in case you can’t find the preferred solution.

SC-L Pill

Best price-performance ratio for low resistance contact.

SC-L is the ideal contact technology for silicone keypads in resistance coded or directly switched applications as well as for safety relevant applications. 

SC-L is technically way superior to any Gold- or Carbon contact and thus THE benchmark contact within the automotive industry.

Unique advantages are:

• Very low contact resistance
• Low contact force
• Reliable switching with a distinctive voltage drop when pill hits PCB
• Endures dust and dirt exposure
• Robust also in humid environments
• Reliable also for rotational actuation - e.g. window lifter
• Complete contact silence / no contact noise

SC-M Pill

The perfect contact pill for rotational actuation.

SC-M is the ideal contact technology for silicone keypads in resistance coded or directly switched applications.

SC-M is technically way superior to any Gold- or Carbon contact and thus THE benchmark contact within the automotive industry.

Unique advantages are:

• Best solution for rotational actuation
• Low contact resistance
• Low contact force
• Reliable switching with a distinctive voltage drop when the pill hits the PCB
• Endures dust, grease and dirt exposure
• Robust in humid environments

For rotating actuations SC-M Pill is the preferred solution. This because the entire surface is super conductive resulting in a very low contact force.

SC-H Pill

SC-H pill technology for switches without gold.

SC-H is the extension of the SC-line to enable gold free PCBs and gold free contacts. It enables significant cost savings without compromising technical performance.

SC-H is the ideal contact technology for silicone keypads in resistance coded or direct switched applications.

Unique advantages are:

• UNIQUE: Gold free PCB and keypad contacts
• PCB with conductive trace in special lead free HASL
• Low contact resistance 
• Reliable switching with a distinctive voltage drop when the pill hits PCB
• Endures dust and dirt exposure
• Robust in humid environment
• Best for rotational & flat actuation
• Very cost-efficient

Carbon Pill / Ink

The ideal contact material to create pills in all shapes and sizes.

The common contact technology for silicone keypads in all shapes and sizes. Carbon pills are typically used for high resistance applications.

Carbon ink is mainly used for complex shapes e.g.rings for central backlighting. 

ClickPad

Unique short stroke feel and sound generated through a combination of technologies.

The world’s most robust and versatile short stroke solution enhances and replaces traditional micro switches.

Smart combination of specially selected metal domes with a value adding silicone base.

The ClickPad system performes beyond expectations regarding all relevant dimensions, e.g. feel characteristic, pre-load, acoustic control, lighting, sealing, redundancy and rotational actuation.

Capacitive

Guide the electromagnetic field.

Abatek provides solutions for guiding electromagnetic fields from the surface to the PCB. Furthermore conductive foils detecting the capacitive interaction right below the surface are offered.

Bridging the airgap by guiding the electromagnetic field down from the A-surface to the PCB board via customized silicone is a very cost efficient and robust solution.

 The capacitive function can be combined with tactile feel and illumination.
