An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal.
