XD relay with manual override knob

An electromechanical relay with manual override knob, comprising

• the electromechanical relay configurable as part of a modular family of electrical switching relays, the electromechanical relay utilizing interchangeable mechanical override components comprising a manual override knob or a blank filler, and being housed within an enclosure capable of containing two or more of the electromechanical relay;
• where the electromechanical relay is selectively constructed to either have the manual override knob or to have a blank filler, wherein the electromechanical relay is configured independently to include or exclude the manual override knob prior to assembly, thus resulting in a plurality of selectable product permutations from a minimum number of unique components;
• a rotary manual on and off override control where the manual on and off control consists of three distinct positions for
• (1) forcing/maintaining the electromechanical relay on,
• (2) forcing/maintaining the electromechanical relay off, and
• (3) allowing the electromechanical relay to automatically turn on and off or to be remotely turned on and off with an electrical signal;
• and
• a printed wiring board contains one or more configurable mechanical device comprising rotary switches or dip switches separate from the main relay actuator and accessible to installers for non-volatile configuration that allows an installer/operator to set device configuration settings.
