The invention discloses a linkage switch of a high-voltage breaker cabinet for a box type transformer station, and relates to a linkage switch. The linkage switch comprises a high-voltage breaker cabinet operating handle, a linkage switch (1), a linkage spacer sleeve (2), a linkage plate (3), a linkage rod (5) and a lower door (6). The linkage spacer sleeve (2) on the linkage switch (1) of the high-voltage breaker cabinet operating handle is opposite to the upper end of the linkage plate (3), the linkage rod (5) arranged at the lower end of the linkage plate (3) is fixedly connected with the lower door (6), the linkage rod (5) is provided with a spring, the upper end of the spring abuts against the lower portion of the linkage rod (5), and the lower end of the spring abuts against the bottom of a cabinet body (4). The linkage switch provided by the invention realizes linkage efficacy under the condition that the high-voltage breaker cabinet is seldom changed.
