The invention provides a rotatable device including a body adapted to be supported for rotation about an axis of rotation. A resilient electrically conductive member is supported by the body for rotation with the body, and has first and second blades, the second blade being generally parallel and spaced radially inwardly of the first blade with respect to the axis of rotation of body. The first and second blades of the resilient electrically conductive member define a battery receiving area therebetween adapted to house a button type battery. A electrically operable device is mounted on the second blade of the resilient electrically conductive member and is centrifugally activated when the body is rotated about the axis.

A rotatable device comprising: a body adapted to be supported for rotation about an axis of rotation; a resilient electrically conductive member supported by the body, for rotation with the body, said resilient electrically conductive member having first and second blades, the second blade being generally parallel and spaced radially inwardly of the first blade with respect to the axis of rotation of said body, the first and second blades of said resilient electrically conductive member defining a battery receiving area therebetween, the battery receiving area being adapted to house a button type battery having a first terminal and a second terminal such that the first terminal of the button type battery is in electrical contact with the first blade of said resilient electrically conductive member, and such that the second blade of said resilient conductive member is spaced apart from the second terminal of the button type battery and resiliently movable toward the second terminal of the button type battery; an electrically operable device having first and second electrical contacts, said electrically operable device being operable when electrically connected to the button type battery by the first and second electrical contacts, said electrically operable device being mounted to the second blade of said resilient electrically conductive member, the first electrical contact of the electrically operable device being electrically connected to the second blade of said resilient electrically conductive member, and the second electrical contact of the electrically operable device being normally positioned in spaced apart relation from the second terminal of the button type battery and movable with said second blade to engage the second terminal of the button type battery when the body is rotated about the axis thereby causing centrifugal force to move said second blade and said electrically operable device so that the second electrical contact moves into engagement with the second terminal of the button type battery when the button type battery is in place.
