The first self-testing Non-Powered Optical Switch/sensor, (NPOS) system over a single fiberoptic cable. This feature, for optical circuit fault detection and indication, provides the option of an electric indicator light at the controlled device, computer interface fault signal or on-off flash of the controlled electrical device if a circuit fault is detected.
The first (NPOS) that is capable of a three-position, four-position, etc. option over a single fiberoptic cable. Examples include a three-position automotive window or door lock switch in an up-off-down configuration.
The first (NPOS) that is capable of a three-way, four-way, etc. for multiple remote switching of a controlled device. Examples include a hall light with two or more remote switches or automotive window, or door lock controls located on the driver’s side and the passenger side to control the same window or door lock functions with two separate switches.
Continuity of Light Signal
The first (NPOS) that utilizes a continuity of optical signal in all switch positions allowing for an always on optical return to the optocontrolling transceiver. With this optical system, there is never an absence of optical signal to indicate a switch position such as utilized in current systems, in turn providing the optical self-testing feature of the Spectraswitch system. This provides fault indication for mission critical switching systems.
Wavelength Varying Potentiometer
The first (NPOS) that is capable of a potentiometer or rheostat operation for motor speed control or dimming an electrical light utilizing a continuous reflected variable wavelength and not a diminishing optical signal strength for control.
Visible or Infrared Options
The first (NPOS) capable of utilizing either visible wavelengths over a single (POS) plastic optical fiber for typical ranges up to 100 meters or infrared over glass optical fiber that would have a range of several kilometers.
Passive light Indicators
The first (NPOS) that can utilize the waste light at the (NPOS) to provide a selective colored optical indicator showing the position of the switch.
The first (NPOS) that utilizes the least mechanical parts of any other optical system allowing for the smallest micro switch for control.
Optical Switching Benefits
The first (NPOS) to incorporate these features into one technology that also includes the typical advantages of optical switching such as: explosion-proof, shock-proof, waterproof, lightning-proof and EMF-proof switching systems.
