This circuit is similar to the Power Connection with the addition of having six toggle switches. With these added switches, one can control different lights, different rooms of lights, or different circuits within your dollhouse. You simply wire to one of the six terminal blocks, tighten down the screws and control that light with the toggle directly behind the terminal block. As with the Power Connection, the Junction Switch is a fused circuit. Each toggle switch is capable of handling up to 5 amps of power at 24 volts so this Junction Switch could be used to switch power to six different displays.
