Note: Our company currently produces the following categories of tactile switches {waterproof type, dustproof type, illuminated tactile switches}.
Domestic spring contact lifespan: 50,000-70,000 times; imported spring contact with single-sided silver plating lifespan: over 100,000 times; stainless steel spring contact: over 500,000 times.
Out of context, a tactile switch refers to a switch whose contact state can be changed without applying much force, so the contact capacity is very small and the structure is simple. After the switch strength is removed, it can only maintain its original state. In other words, a suitable switch can be pressed with very little force, without a definite single contact button switch. Currently, membrane switches and small micro switches can both be considered as Tactile switch mostly composed of two insulating films structurally, or made of thin elastic metal in the shape of a butterfly spring, with the spring connecting printed circuits.
