Snaptron, Inc.

Our tactile domes are momentary switch contacts that, when used in conjunction with a printed circuit board, flex circuit, or membrane, become normally open tactile switches. Tactile domes are placed onto the substrate with pressure sensitive adhesive tape (Peel-N-Place Array) or captured in a membrane-type pocket design.

For nearly 30 years, Snaptron has been the industry leader in providing high-quality tactile metal switch contacts and snap domes, along with complementary equipment for a wide variety of industries. Our customer service and breadth of product selection (variety of dome styles, sizes, and forces available) are second to none.

Snaptron carries more than 10 different standard dome styles, with sizes ranging from 4mm to 25mm. Custom tactile domes can also be created with minimal lead times.

Snaptron works directly with customers worldwide. Our goal is to provide the best customer service and industry expertise to make our customers’ projects a success. We do not use distributors, so please contact us directly. We look forward to working with you!

Peel-N-Place Dome Arrays


Snaptron tactile metal domes are often placed onto a printed circuit board or flex circuit using a pressure sensitive adhesive tape – referred to as Snaptron’s Peel-N-Place dome arrays.

Two options for Peel-N-Place Arrays:

Standard – A single dome on a square piece of adhesive tape (packaged in sheet form)

Custom – Multiple domes placed in the exact locations you require (including cuts for “keep out” areas.  Send Snaptron a PNP drawing.
