A Relay is generally used when it is required to control a circuit by a separate low-power signal, or when several circuits must be controlled by one signal. For my 40 A stove situation, an SSR meant almost 100 W dissipation. Systems based on relays with low-voltage control circuits permit switching the power to lighting loads from an arbitrary number of locations. Incidentally, I have yet to see one of these larger devices that needs a series resistor on its control voltage input - they just take the control voltage. Inspired by industrial systems that relied on relay switches to control motors, lights and other industrial equipment, vintage remote control wiring systems used relays to switch a current; these relays, in turn, were controlled by small light switches operating at a low voltage comparable to that of a doorbell. perl `rename` script not working in some cases?
