Tactile Metal “Key-Pad” Dome Switches

Featured Product from Keystone Electronics Corp.


Keystone Electronics Corp. debuts a new line of snap action “Key-Pad” dome contacts specifically designed as a momentary contact for printed circuit boards, flex circuits, membrane switches and discrete switches. 

Equipped with a unique four-legged shape, these innovative dome switches offer enhanced durability, reliability and versatility while maintaining exceptional tactile feel for single or double-sided printed circuit boards, flex circuits, and membrane switch panels.  Offered in Mini (.331” Dia), Compact (.394” Dia) and Maxi (.480” Dia) styles with trip forces from 7.8 oz. to 14.8 oz.  

Manufactured from Nickel-plated stainless steel, these domes are built for harsh environments such as Microwaves, Vending Machines or any application requiring substantial tactile response along with extensive actuation life.  

Supplied on tape and reel, they are ideal for use with most vacuum and mechanical pick-and-place assembly systems.  Domes are also supplied in convenient tubes for individual placement applications.  Availability is from stock through Keystone’s global distribution network.  Online ordering is accommodated. 

Adhesive backed spacer material for creating custom “Key-Pad” arrays is also available.

Spacer material is designed to provide the proper spacing between the circuit board, the dome and the device graphic layer.  Made from clear polyester, the spacer material is supplied in sheets for customization and assembly/inspection ease.
