CoActive KDM offers a broad range of metal domes to meet our customers most stringent requirements, our most popular metal domes include:

Round domes; with superior life and tactile; options available exceeding 5 million actuations

• Side-cut domes; small footprint, ideal for side key applications
• Venting options to meet your application
• Dimple domes to meet robust environmental performance
• Plated domes, providing reduced electrical resistance
• Combination Arrays, mixing dome type, trip force and diameters & including the above features
• Actuator on domes, delivers enhanced tactile within customer’s assembly
• Total interface solutions, we design and supply domes integrated with keypads, backlighting and PCB/FPC’s ensuring optimized solutions

Standard Dome Arrays

• Metal domes are available in a wide range of trip forces and tactile feel
• Round domes in diameters from 3.5mm to 5mm to suit your configuration
• Side cut domes starting from 3mm x 4mm
• Available in internally & externally vented designs to meet customer requirements
• Very thin switch profile; typically 0.10 mm thick cross section with an overall height of 0.28 mm including the metal dome
• Short crisp travel ( 0.16mm - 0.33 mm) with excellent tactile feel
• Part profile and size changes are quickly made using software driven lasers
• Produced by high precision, in-house controlled tooling

Value-Added Dome Arrays

Actuator on dome side key assembly

Dome arrays with plastic light guide

ESD/RFI shielding

Actuator on dome

Adding any one of many features can enhance standard Metal Dome arrays

• An ESD/EMI shield can be printed onto the top surface
• On unsealed designs where contamination may be a concern, a "dimpled" dome can cut through debris to maintain switch operation
• Varied tactile switch forces can be designed into the same array by using multiple metal dome technologies
• Our “actuator on dome” will control and optimize the tactile performance of the array, this reduces the sensitivity of the dome and keypad assembly tolerance easing the final assembly process and reducing customer rework and scrap
• KDM is experienced in providing dome arrays as part of a fully integrated assembly, tested and ready to go; with vertical integration we are able to manufacture the keypad, light-guides (both traditional injection & thin light guide foils) and plastic injection/IMD housings. As we own, and therefore control, more of the package we ensure the assembly is optimized for performance and costs. We can add the PCB and other components to provide a fully functional module solution

Flexible Manufacturing Processes

Dome stamping and placement options:

• CoActive’s proprietary ‘multi-up’ TM process for high volume projects, with automated, simultaneous dome punching and placing guarantees quality at the best cost
• Flexible high speed “Pick and Place” processes for low to mid-volume, allowing full flexibility and ideal for supporting project ramp up
• Class 10,000 clean rooms are installed to ensure we control the environment and minimize contaminates from the array

Array cutting options:

• High volume reel to reel laser cutting for rapid cut path revision and zero tooling costs as well as rapid prototyping
• Die cutting and lamination lines provide high tolerance adhesive and spacers for internally vented arrays
