The utility model relates to mechanical switch field discloses a kind of connecting mechanism of mechanical switch, adopt spring and
copper pipe combination, spring can be folded arbitrarily,
copper pipe can keep spring position state, since
copper pipe internal damping coefficient is small, copper pipe can guarantee spring to slide in copper pipe inside arbitrarily, spring and copper pipe combination not only can guarantee connecting mechanism to shuttle and turn in narrow space continuously, and further improve the strength and reliability of connecting mechanism;For the installation position and external environment of various kinds of mechanical switch internal parts, in the case where some reserved space is smaller, the parts connection of mechanical switch can also be satisfied with various complex situations, using ingenious design, make connecting mechanism become an independent component, disassembly is convenient, can be operated in each direction, convenient for later maintenance and replacement, improve the versatility of connecting mechanism.
