T-series snap domes(metal domes) are triangle shape switches that can be mounted on double-sided printed circuit boards, flex circuits, or in membrane switch panels, and they are widely used in the electronic toys, desktop phones, medical equipments.

We have the diameter of T-series snap domes is from 4mm to 12mm, and the force is from 100g to 5000g. The advantage of the T-series snap domes in the same diameter is that with the higher actuation force, normal the force can over the 600 gram.

As most of the triangle snap domes have two legs, you can insert into the hole of circuit board, it can be fixed on circuit without any adhesive tape, it will save much time and cost for production. But we don't recommend to sold the snap dome to PCB, it will affect the function, such as the life cycle and clicking feeling.

According to the structure of the T-series snap domes, it divided into four items:

1. NT-series: Without legs

2. ST-series: With two short legs: 0.8*0.8mm(width * length of the legs)

3. MT-series: With two middle legs: 0.8*1.5mm

4. LT-series: With two long legs: 0.8*3.0mm

According to the thickness of the PCB, you can select the suitable legs, then insert the legs to the holes of the PCB to be fixed.
