Feature: 1. The button is an all-metal structure of the operating head and the fixed middle plate. Its ruggedness and reliability are unmatched by any similar products. It can be removed from the front. 2. All contacts have the dual function of switching circuit and self-cleaning. When the switch is operated, the contact surface is wiped clean by sliding closure, so the contact can be guaranteed in low voltage and low current (5V, 5mA). 3. Control button XB2 series mechanical life and electrical life reaches 3 million times, electrical life. 4. Equipped with a built-in screw connection which is safer to use. 5. The XB2-B(E) series has powerful functions and can form a complex multi-function control system, which is very convenient to operate.
