Rubber Keypad Assemblies

Rubber keypads are used in many industries such as telecommunication devices, consumer and home appliance products and game systems.

 

There are several types of rubber keypads such as traditional silicone rubber keypads, plastic keycaps over rubber keypads, and In-Mold Decorated (IMD) keypads. Silicone rubber keypads are typically compression molded. Custom keypads can combine colors, light pipes and epoxy coatings. A rubber keypad assembly offers the ability to design three dimensional keytops, oversized key surfaces, and improved tactile response. Graphics can be silk screened or painted for additional colors and laser etched for texts and icons. Rubber keypads can also be backlit for icon and switch indication. Keycaps and IMD technology, once only used in high volume cell phone type applications are now cost effective options for many applications. Vmanx integrates the silicone rubber keypads with tactile metal domes and its membrane switch technology to offer complete interface assemblies.
