Snaptron offers Peel-N-Place arrays which is the most common way to secure tactile domes to your PCB or flex circuit.  Typically, metal domes are not meant to be soldered.  When a dome is actuated, the center of the dome collapses making contact at the center.  As this happens, the legs of the dome flex out. […]

Choosing Tactile Dome PCB Board Plating

When evaluating the type of PCB pad plating you will need with tactile dome contacts, it is important to ask yourself two questions: 1. What is the product life cycle requirement? 2. What type of contact resistance do I require? The circuit pad base is often copper, which will oxidize if not plated. Nickel has […]

Placing metal domes quickly and accurately in membrane applications can be tricky. Typically, domes arrive in bulk form and are packaged in jars. Getting domes placed quickly can be challenging and “double doming” common. At Snaptron, we have invented a proprietary technology that allows for fast placement and assures only one dome is placed in […]

The Importance of Venting a Metal Dome

The movement of air in and out from under the dome is called “venting” and it is important to have so the metal dome functions properly. Lack of venting can cause adverse effects on the feel and function of the switch. Venting metal domes is crucial in order for the dome to feel the way […]

What are the benefits of incorporating this dome contact into medical devices? How is that accomplished with existing devices? The DT-Series domes can produce two electrical contacts with a single dome. Benefits of metal domes include: low profile high reliability competitive price This is a new innovative technology that is open to the creativity of […]

What metals or other materials are used to make dome contacts? Metal domes are made of stainless steal and can be plated (typically with Nickel or Gold) to lower contact resistance. All standard DT-Series domes are stainless steel with nickel plating (ROHS compliant). Metal domes are extremely versatile and can be used in a wide […]

How were you able to create a less-complex, longer-lasting, easy-to manufacture component than existing tact switches? Metal dome contacts are essentially a single piece of stamped stainless steel with optional plating. Tact switches typically include a housing in which a metal dome resides, an enclosure, and often a built in actuator. Therefore manufacturing of tact […]

What was the development process like, and how long did it take to get the product to market? What challenges did you encounter during that process? Once the dual action dome concept was created, researched, and tested, the production of the first DT-Series dome took less than 2 months. The DT-Series are essentially SPST metal […]

What led Snaptron to develop the DT-Series dome contact with IntelliTac technology? The DT-Series dual action dome was created in response to a customer inquiry. The customer wanted a switch that, once activated, would stay permanently in the “on” position for the life of the product. They wanted to be able to test this product […]
