Within the ASCO family of Industrial Control Products reside world recognized lighting control and specialty products including design optimized mechanically held lighting contactors that are the industry standard for quality and performance.
The current generation of ASCO ICP products reflect a 100 year tradition of applied technology and progressive design improvement. Our 918 lighting contactors employ a patented single, bi-directional solenoid operator that is mechanically held in both on and off positions. The 918 in the truest sense is mechanically held not relying on magnetic latches or impressed current to maintain contacts in the open or closed position. This inherent design feature results in "zero" control voltage and current flowing through the coil since the coil is de-energized once the main contacts are driven to the open or closed position. Therefore, the 918 will not generate the ever present AC hum and continuous power drain characteristic of electrically held designs.
Innovative variations on transfer switch technology and lighting control are found in specially engineered ASCO ICP products for by-passing commercial dimming systems.
