A latching switch relay has a selector hub which moves a contact carrying rotary switch shaft along with its contacts from a first to a second position. The selector hub moves to a corresponding first and second position to cause movement of the shaft by remote actuation of a rotary solenoid or by manual operation of a handle linked to the selector hub. A spring is engaged with the selector hub to resiliently urge the switch shaft into its first and second positions.
