Abstract: Switches have been developed to connect a source and the load by opening or closing a circuit. This study developed an inexpensive but highly responsive capacitive switch prototype for lighting and motor control systems as a fine-tuned alternative. The control switch consists of a capacitive touch sensor mounted on a standard switch box with an internal control circuit board. Moreover, a capacitive touch switch is applied in one-way and three-way light switches and forward-reversed motor control. We devised a practical application of a capacitive touch switch to control a lamp from two locations and use it to function as a three-way button switch. The prototype was installed in a wooden case consisting of the following components: magnetic contactors, control relays, an Arduino board, a lamp, a capacitive touch control switch for dimmer light, and motor control. A series of test and analyses were performed on the prototype circuit to ensure the correct and targeted functions, meet the desired specifications, and operability and reliability. Based on the test performance, the level of acceptability for its safety (maximum voltage = 12VDC, temperature = 85 °C) and responsiveness (0.05) was highly acceptable with 25% cheaper costs than existing commercially available similar models.
