What is contact grease? An explanation of its role and applications as a lubricant to prevent contact failure.
"Contact failure" occurs in electronic devices, control panels, and automotive connectors.
One of the causes is oxidation or wear of the contacts, as well as corrosion due to moisture.
This is where contact grease is used.
Contact grease is a lubricant that stabilizes the contact state while protecting metal contacts, and it can provide effects such as:
✔ Prevention of contact oxidation
✔ Moisture and rust prevention
✔ Reduction of wear
✔ Suppression of contact failure due to vibration (fretting wear)
It is particularly used in automotive connectors, terminal blocks, switch contacts, and sensor terminals to enhance the longevity and reliability of contacts.
It is important to note that contact grease and conductive grease serve different purposes.
The main purpose of contact grease is "contact protection," while the main purpose of conductive grease is "assistance in conductivity." Selecting the appropriate product according to the application is crucial.
For those struggling with contact failure or terminal corrosion, it is important to understand the differences between contact grease and conductive grease and to choose the right product accordingly.
