To complement our diverse variety of domes, Snaptron offers E-Series metal domes with various features. Our E-Series domes come in three different shapes – triangular, round, and oblong. E-Series triangle tactile domes are an inexpensive alternative for projects with relaxed tolerance requirements and cost constraints. Contact Snaptron to see if E-Series domes may be right for your application or check out our WT-Series triangle domes for higher forces and life cycle ratings.

Contact Snaptron for pricing, to order, or to request samples of E-Series domes.
