Common failures of precision shrapnel 'hardware'

Generally speaking, the service life of precision shrapnel is relatively long, and some precision shrapnel can last up to 1 million times. It stands to reason that there are relatively few failures. So, what are the general reasons for the failure of precision shrapnel? Combining years of experience in dealing with products, Dongguan Hardware is here to share with you. Common failures of precision shrapnel are as follows: Over-travel: For example, when the shrapnel is pressed by hand, the stroke is uncontrollable, which may cause over-travel and destroy the precision shrapnel. Overpressure: For example, when the shrapnel is pressed by hand, the pressure is uncontrollable, and the load may exceed the normal preset pressure value of the shrapnel, which may cause overstroke and destroy the precision shrapnel. Excessive crushing: Use sharp objects or nails to cause scratches with precision shrapnel. The contact is too large: the contact design is unreasonable, resulting in the contact not working well with the shrapnel, which affects the normal use of the precision shrapnel. The contact surface of the precision shrapnel is unbalanced: the periphery where the shrapnel is placed is unbalanced. Poor contact: install precision shrapnel reasonably and pay attention to reserve space for precision shrapnel. Resistance value: The resistance value of precision shrapnel is relatively fixed, for example, stainless steel is less than 100 ohms, nickel plating is less than 1 ohm, and gold plating is less than 0.1 ohm.
