Originally, there is no professional name called snap dome in the early days. And a snap dome is made of metal material. Because it is a dome, it can bounce upward and be concave downward (convex and concave). Its initial state is convex upward, and it will concave downward when the operator exerts a force, and then rebounds after the force is removed. This kind of elastic metal material is uniformly called metal dome or snap dome. Later, when metal dome switches were introduced into China, many people were used to calling them metal dome switches. Metal domes also referred to as metal snap domes or tactile metal domes Wootliff, Raoul (18 May 2016). "Israel successfully tests shipborne Iron Dome missile interceptor". The Times of Israel . Retrieved 18 May 2016. [ permanent dead link] These results partly support critics (like Theodore Postol) of Iron Dome's effectiveness during Pillar of Defense. However, they also partly support proponents (like Uzi Rubin) of the system's effectiveness during Protective Edge. With outside forces affecting the life of your dome, the best course of action is to submit the dome to a test within your specific application with an actuator similar to the use it will receive. If a dome is being used in an office setting, only used once in the morning to turn a machine on and once in the evening to turn the machine off, then life-cycle testing is not the most important factor. If a dome is being used in a harsh environment, like a switch for entry of an armored vehicle, where the users are large and use much more force then in an office setting, you must adjust your testing criteria. The life-cycle testing for the armored vehicle will need to have a higher actuation force than the standard 110%, some companies expose domes to testing of up to 25 lbs. to see if they will hold up to their specific application.

Notes: It is more common for triangular pans to have feet, and for round shapes, there are also buttons with feet. Relatively speaking, the round pan pieces have a shorter stroke, the cross-shaped pan pieces have a larger stroke, the ellipse has a smaller diameter and less force, and the triangle has a shape that can reach a higher level. It can reach 3000gf, and all the pots can be silver-plated or tin-plated. The life of pots of different shapes can be the same. The life of pots in China is generally between 100,000 and 700,000 times.

In comparison with other air defense systems, the effectiveness rate of Iron Dome is very high.

But the reality is different, and these constraints forced us to think hard. There are parts in the system forty times cheaper than the parts we buy normally. I can give you even a scoop—it contains the world's only missile components from Toys R Us... One day I brought to work my sons toy car. We Passed it among us, and we saw that there were actually components suitable for us. More than that I can not tell. .
