In daily use, attention should be paid to the waterproof condition of the interface. After using micro sockets for a long time, there may be some dust or debris inside the interface. For the removal of dust and debris, it is not advisable to wipe with a damp cloth. Wiping with a damp cloth can easily cause accidents such as electric shock, and should not be contaminated with water. If the metal chip of the terminal inside the hardware shell is contaminated with water, it may cause a short circuit in the socket circuit and may also cause a fire. The product uses materials, hardware shell: high-strength stainless steel, plastic body: environmentally friendly and high-temperature resistant LCP plastic, pins: high conductivity copper. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life.
