WebA switch is a device that opens and closes the circuit, like a light switch. It is analogous to a valve in a water circuit, as shown on the right side of Figure 19.12. With the switch open, no current passes through the circuit. With the switch closed, it becomes part of the wire, so the current passes through it with no loss of voltage. WebMar 27, 2024 · It will provide 2 low-voltage wires, and when they are shunted (shorted), the relay operates. This means it'll have at least 8 wires: 4 for the DPST contacts, 2 to supply …
