Does your design require a durable and flexible protective solution?
Rubber keypads can provide outstanding and reliable performance in rugged working conditions where components may encounter water, dust, chemicals, vandalism or extreme temperatures. The Rubber Keypads works like a gasket to completely seal your device. While you gain all of this additional protection to your Human-Machine Interface (HMI), you won’t need to sacrifice device functionality or appearance.
We can provide you with the ideal operating solution
RH can review your 3D CAD files and help you design the latest in rubber keypads. If you know that an HMI is destined for an extreme working environment, we can help you produce this type of rugged keypad. Our experience will transform your product needs into a solution that will safely operate within the most severe working conditions.
A Robust Design
With a bold appearance and tactile response, your Rubber keypads can be designed to seal a specific section of your HMI, or completely sealed your product from the harmful influence of the outside world.
The many options in rubber keypad design
By adding this type of rubber keypad to your HMI, you provide a very definite tactile feedback. This feedback may be necessary to your machine operators in noisy and dirty environments or where the operator is wearing gloves, headgear and PPE. Over-printing the keys can provide a bold visual appearance while illuminating the keypad with user-friendly backlighting is also a fantastic product option. The design of rubber keypads can also be very flexible and can incorporate complex or irregular shapes. If you require a hard button for your keypad interface, this can be incorporated with the use of plastic moulded keytops.
How is a rubber keypad constructed?
Rubber keypads are made using compression moulding techniques and can be made with multiple colours and impressions. To backlight a keypad, you mould the keys using translucent rubber which is then sprayed or printed. Finally, the key is laser etched for detail and shape. For constructing a hard button keypad, injection moulded keycaps are fitted to a rubber mat. Metal or polyester dome arrays can also be added for extra tactile feedback.
Solutions for different market sectors
Under the surface of a keypad, you will find delicate circuitry that is vulnerable to the surroundings. Rubber keypads are often the ideal solution for operating in market sectors where you experience difficult conditions.
- Harsh industrial environments
