An electrical contact system includes a pair of static contacts, a rotatable member disposed between the static contacts and rotatable about a rotation axis between a first position and a second position, and a movable contact mounted on and rotated with the rotatable member. A pair of opposite ends of the movable contact are in electrical contact with the static contacts when the rotatable member is rotated to the first position. The ends of the movable contact are separated from the static contacts when the rotatable member is rotated to the second position. The movable contact has a Z-shape and is slidably mounted on the rotatable member. The movable contact slides under a pushing force from a first static contact of the static contacts toward a second static contact of the static contacts to be in electrical contact with the second static contact.
