Customers often report that the resistance value of the membrane switch button is too high, causing the button to fail, or sometimes it is, and sometimes it cannot be pressed. Frequent detection, if it is caused by the membrane switch button, it is caused by the excessive resistance of the membrane switch circuit. Our company has been engaged in the production of membrane switch buttons for more than 10 years, and has accumulated rich experience. The resistance loop of the switch buttons can be controlled within 10 ohms, so that the buttons will be hit by a large number of times and the keys will not be false. Friends in need can contact me.
