RSP, Inc.

United States

RSP is a membrane switch manufacturer with operations in the US and China. Our team has extensive experience creating membrane panels for a variety of uses for our clients.Membrane switches, also known as membrane panels or keypads, are electrical switches with a user interface to control equipment and machines. The top layer is typically the graphical interface, also known as a graphic overlay, which identifies the functions being controlled using icons or text. Next, below the graphic overlay, are adhesive layers and a spacer layer to bond the circuit to the graphic overlay. The circuit layer is where the magic happens. Conductive inks are applied through a silk screen-printing process. In some cases, the membrane switch requires additional insulating layers made of non-conductive materials to prevent short-circuits. To complete the switch, an additional adhesive layer is used on the rear of the circuit to bond it to the bezel or substrate. To improve the user experience, membrane switches typically provide haptic or visual feedback. A great example of haptic feedback is through the use of tactile metal domes or poly-dome construction. When this type of feedback is used, a user will press a key or button and feel a ‘snap’ action as the dome is compressed. This type of key might also provide some audible feedback from the ‘snap’ of the dome. As for visual feedback, the membrane switch can have embedded LED indicators or feedback can be visually displayed on a separate display or monitor. Typically the membrane switch circuit only has resistors and LEDs mounted to it, as opposed to a circuit board which has limitless options.

Believe it or not, our beginning started with printed graphics. Some of the first products RSP produced were overlays for Harley Davidson and advertising banners for Schlitz Brewing in Milwaukee, WI. Those first customers set a very high standard for RSP, a standard we continue to meet and exceed to this day. Over the past 50+ years, we have created a variety of high-quality printed graphics. Our experience helped us create a highly proficient printed graphics department to create custom graphic overlays and other custom graphics that bring our customer’s products to life.

RSP manufacturers silicone keypads, which are ideal for a range of products. The average person comes in contact with silicone keypads, also known as elastomeric keypads, almost every single day. Because of their low cost, flexibility of design and reliability, silicone keypads are used in a variety of industries, including medical, marine, and military, in addition to consumer applications, such as TV remotes and electronic games. Resistance to both high and low temperatures (-55° C to 250° C) Minimal noise generation due to soft and elastic contact structure Minimal abrasion and high resistance to sulfur dioxide and oxidation even in heavy humidity Designed for snap ratio and tactile feedback Translucent color which is excellent for backlighting Multi-color designs easily accommodated Water and contamination resistant Coating options for increased durability chemical and environmental resistant
