<\/div>\n

Four legs series metal domes (also named as 4-leg tactile metal domes, F-series metal domes<\/a> or cross metal dome) are four-legged dome designed specifically for mounting on a wide variety of switching surfaces, including single or double-sided printed circuit boards, flex circuits, and membrane switch panels, where traces of negative and positive can designed under the dome on the same side of circuits.<\/p>\n\n\n\n

The four legs metal dome can achieve high actuation forces and tactile relative to their size, in the meantime, they are available in a wide variety of sizes and actuation forces.<\/p>\n\n\n\n

F-series metal domes has better click feeling than Circle and Oblong series domes, and its life cycle is longer than Triangle dome, its normal life times are >= 1 million. The height of it is higher than other domes, based on the same diameter, force and clicking ratio. That\u2019s why the cost of cross metal dome is higher than others.<\/p>\n\n\n\n

In addition, the size of F series metal dome can be made from 5mm to 20mm in a range of (trip) force, typical 125- 500 gf. The trip force, rebound\/return force, click, travel, and height, etc., can be adjustable according to clients’ request. No matter what size or force you require, we’ll do our best to produce it.
