A modular transfer switch () and actuator () wherein multiple transfer switches are connectable in linear arrangement with the actuator such that the actuator controls the position of all of the transfer switches. Each of the transfer switches () includes a contact assembly () that converts over-rotation of the drive linkage () in the transfer switch to added pressure between the load contacts and the power contacts in the contact assembly. The actuator has an embodiment wherein a joint () that connects counter-rotating arms () is linked to the armature of a linear motor () and spring tension from springs () is additive to the closing force applied to the transfer switches ().
