Our experienced design and product management teams are ready to work with you to design custom membrane switches that will meet the unique requirements of your program. We offer a complete line of product features to provide you with the look, feel and performance that meets your needs. Designs Midwest offers textured keypads with clear windows for devices with LCD’s.
Metal Keypad Design and Manufacturing
We manufacture our metal keypad assemblies to satisfy customer specific applications such as custom language and function key output, custom dimensions and mounting styles and custom programming. Together with stringent quality control systems and OEM/ODM experience, we can assure the highest quality that enhances full functionality and capability.
Our metal keypads can be made of Stainless Steel or Cast Zinc, with custom dimensions, layouts and installation schemes. We can design and manufacture dustproof, waterproof, shake-proof, drill-proof and bullet proof assemblies. They can be made to IP 65 specifications. Other options are USB and PS/2 interfaces.
Design and Manufacturing
Designs Midwest offers design and manufacture of Capacitive Touch Sensing Technology switches. Capacitive touch sensors are used in many devices such as laptop trackpads, digital audio players, computer displays, mobile phones, mobile devices and others.
Today design engineers are selecting capacitive sensors for their versatility, reliability and robustness and cost reduction over mechanical switches. This technology is perfect for waterproof devices.
Rubber Keypad Design and Manufacturing
Designs Midwest has years of experience in the design and manufacture of silicone rubber keypads for a wide range of applications and industries. Today Silicone Rubber keypads are used extensively in consumer, automotive and industrial electronic products providing a low cost and reliable switching solution. This technology utilizes the superior compression molding properties of silicone rubber to create reliable and long lasting switches. Depression of a key uniformly deforms the webbing to produce the desired tactile response. When pressure is released, the webbing returns to its neutral position with positive feedback.
To create an electronic switch, a carbon or gold pill is bonded to the bottom of the key which makes contact with a pad on the printed circuit board upon depression of the key.
Designs Midwest provides excellent choices for both simple and the most stringent of design specifications. Unique processes allow light pipes and windows to be incorporated as an integral part of the keypad during manufacture, making them a single sealed component, less likely to fail or separate in use.
Designs Midwest has capabilities that include all molding processes, laser etching, screen printing, pad printing, in house graphics, and custom finishes offering an economical quality solution for your design requirements. Designs Midwest also offers plastic key tops according to customer needs.
