Description: The bedside door fixture delay circuit features a straightforward design and offers cost-effectiveness. It is constructed using a hex inverter CD4069.

The bedside door fixture delay circuit employs the hex inverter CD4069, which is a versatile integrated circuit (IC) commonly used in digital logic applications. This circuit operates by delaying the activation of a light fixture or similar load when the door is opened or closed.

The primary components of the circuit include the CD4069 hex inverter, resistors, capacitors, and a relay or transistor to control the load. The CD4069 consists of six inverting gates, allowing for various configurations to achieve the desired delay timing.

In operation, when the door is opened, a signal is sent to the input of one of the inverters. The inverter outputs a low signal, which is then processed through a resistor-capacitor (RC) timing network. The values of the resistor and capacitor determine the delay duration before the output transitions to a high state, activating the relay or transistor. This activation can power the light fixture, providing illumination for a predetermined period.

The simplicity of the circuit allows for easy adjustments of the delay time by varying the resistor or capacitor values. Additionally, the use of the CD4069 ensures that the circuit remains cost-effective while providing reliable performance. The compact nature of the design makes it suitable for bedside applications, where space may be limited. Overall, this delay circuit effectively enhances convenience and safety in environments where immediate illumination is not necessary upon door operation. Bedside door fixture delay circuit has a simple structure, the advantages of affordable, the circuit with a hex inverter CD4069 composition.
