An electrical switch (10) comprises switch contacts (100, 104) having a closed condition and an open condition. The switch (10) comprises an actuator (40) movable in a first direction (110) in a first stroke to close the contacts (100, 104) and movable in the first direction in a second stroke to cause the contacts to open. A rotatable bar (70) is carried by the actuator (40). The switch (10) includes a mechanism (14, 94, 96) for rotating the bar (70) in response to movement of the actuator (40) in the first direction (110) in the first stroke, to locate the bar in a latching position to hold the contacts (100, 104) in the closed condition. The mechanism (14, 94, 96) also rotates the bar (70) in response to movement of the actuator (40) in the first direction (110) in the second stroke, to move the bar from the latching position and to cause the contacts (100, 104) to open.
