Abstract
A switch actuation device includes a first actuation portion driven by a first moving member and a second actuation portion driven by a second moving member. The switch actuation device further includes a first lever, a second lever, and an actuator. The first actuation portion contacts the second lever to swing the second lever toward the actuator connected to a switch when driven by the first moving member. The second actuation portion swings the first lever to cause the first lever to move the second lever closer to the actuator when driven by the second moving member. The actuator is driven by a combination of the swing of the second lever caused by the first moving member and the movement of the second lever caused by the second moving member so as to turn on the switch.
