Multi-Way Switch Master-Slave Relay Control to Cut Wiring Cost

The patent divides the traditional multi-way switch system into two distinct roles: a master switch that contains the intelligent control unit and sophisticated processing capabilities, and one or more slave switches that have simplified circuitry. This segmentation allows the system to achieve the same control functionality as two intelligent three-way switches and an intelligent four-way switch while using fewer resources, as only the master switch requires full intelligent capabilities

The slave switch acts as a simplified copy or replica of the master switch, containing only the essential switching circuitry without the full intelligent control unit. This copying approach allows multiple slave switches to be deployed in the system without proportionally increasing resource consumption, since each slave is less complex than the master but together they provide equivalent control functionality

By segmenting the system into a master switch with full intelligent capabilities and slave switches with simplified circuitry, the patent enables differentiated manufacturing processes. The master switch can be manufactured with higher complexity components while slave switches use simpler, less expensive components, reducing overall manufacturing cost while maintaining complete control functionality

The slave switches are designed as simpler, less expensive units that can be manufactured at lower cost. While they lack the full intelligent capabilities of the master switch, they fulfill their specific function in the multi-way circuit effectively, providing an cost-effective solution that reduces overall system manufacturing cost
