Feature:1. The button is an all-metal structure with operating head and fixed middle plate. 2. The firmness and reliability are incomparable to that of any similar product. 3. All contacts have the function of switching circuit and self-cleaning. The surface of the contacts is wiped off by sliding closure at each operation of the switch. Therefore, in low voltage and small current (5V, 5mA), the reliability of contact can still be ensured in use. 4. Control button XB2 series mechanical life and electrical life are up to 3 million times. 5. Built-in screw type wiring, more security,the function is strong, can constitute a complex multi-functional control system, operation is very convenient.
