Wiring Diagram Q638
Q638 is a popular model of quartz clock, and it has a few electrical connections that are worth noting.
The main switch, labeled "xy" in the diagram, controls the main power supply to the clock. When it is in the "on" position, power is supplied to the oscillator, which produces the time signal. When it's off, the oscillator is turned off and the clock stops working.
There is also a small button labeled "start stop", which controls a separate circuit that starts and stops the oscillator. When the button is pressed, a relay is activated, which connects the start switch to the control circuit. This allows the oscillator to start running and the clock to display time. When the button is released, the relay deactivates, disconnecting the start switch and stopping the oscillator.
In addition, there are a few other components on the diagram that are related to timing functions. The crystal oscillator (labeled "XO") produces the time signal, and the divider circuit (labeled "divider") divides the signal down to produce the hours, minutes, and seconds.
Overall, the Q638 clock is a simple but reliable device that can provide accurate timekeeping for many years. If you're working with one of these clocks and need to troubleshoot or modify the wiring, be sure to follow the wiring diagram carefully to avoid any damage to the device.
