A limiting switch suitable for a testing device is provided. The testing device includes a fixed frame and a clamping element pivoted to each other. The limiting switch includes a first rod, a second rod, a first switching element and a second switching element. The first and second rods are fixed to the clamping element. The first and second switching elements are pivotally connected to the fixed frame. When the clamping element is pivoted along a first direction, the second rod pushes the second switching element to pivot and the first rod is moved to contact with the first switching element. When the clamping element is pivoted along a second direction opposite to the first direction, the first rod pushes the first switching element to pivot and the second rod is moved to contact with the second switching element.
