Abstract
A switch actuator is provided in which any one of a plurality of rotatable cams is capable of actuating a single switch simultaneously with controlling another mechanism, such as a gas valve that is associated with that particular rotatable cam. When used in conjunction with a kitchen range, each of the rotatable cams controls an associated gas valve which, in turn, controls the flow of natural gas to an associated burner. Each of the rotatable cams is disposed within an associated one of a plurality of openings formed through the thickness of a movable member. The movable member is attached in sliding relation with a stationary member which, in turn, can be attached to a stationary device such as a kitchen range. Each of the openings formed through the thickness of the movable member is provided with an edge that is shaped to perform the function of a cam follower. This cam following edge is disposed in contact with a cam surface attached to the rotatable cam. When the rotatable cam rotates about its central axis, the cam surface moves into contact with portions of the cam following edge of the opening and causes the movable member to move relative to the stationary member and actuate a switch which provides electrical current to a plurality of igniters.
