Brand Name: VIT Max. Current 100mA Max. Voltage 30V DC Max. Working
Pressure 50V DC Membrane switch: Thickness is above 0.7mm, Pressing
life-span is over one million times, have fine hermetic ability.
The metal dome is made of stailess steel and we can embed metal
domes into the membrane switches if you want to get more strong and
clear tactile feedback. At present, the metal-dome-button has
already been used in a great deal of machine, because it has very
steady force and clear click. Its life-span can reach 1 million
times at most, and the strong environmental adaptive capacity
enables metal domes to work in -40+80. The metal dome membrane
switches have the following characteristics: 1. Have strong and
clear tactile feedback; 2. Have strong environmental adaptive
capacity; 3. The effective area is largemoderate.
