Triangle metal dome (triagle tactile metal domes) is triangle shaped metal dome which is designed for mounting on single or double sided printed circuit boards, flex circuits and membranes, where a Via is run through the circuit board.

Applications requiring a good click feeling but limited to narrow space, such as small, hand-held devices, are a perfect fit with our Triangle series metal domes. On the same diameter, we cag get biggest force from triangle dome. The Trip force which can reach up to 6,000gf (6kg), so this triangle tactile dome can be used as heavy force control switch to avoid careless operation.

Most of triangle dome has two legs (feet) which can insert into the hole of circuit board, so that it can be fixed on circuit without any adhesive tape and can be used in high temperature. Sometimes people named it as "metal dome with legs".

Here are most popular legs size for triangle dome

legth: 0.8mm, 1.5mm, 2.0mm(seldom used), 3.0mm
Width: 0.8mm, 1.0mm

The size of T series metal dome is from 5mm to 13mm in a range of (trip) force, typical 150-6,000gf. The trip force, rebound/return force, click ratio, travel, and height, etc., can be adjustable according to clients' request.

We don't recommed soldering its leg on circuit which reduce life cycle and clicking feeling. You can also visit our blog for more information such as how to assemble triangle dome and other technology about triangle metal dome.
