<h2><strong>Introduction</strong></h2>Panel indicators, pilot lights and 91-NWA120-CAO are all electrical components used for signaling purposes. They are very popular in electrical & electronic devices of all sorts, ranging from industrial automation to consumer applications. <h2><strong>91-NWA120-CAO Application Field and Working Principle</strong></h2>91-NWA120-CAO is one of the most widely used panel indicators. It consists of a double-pole single-throw(DPST) switch, a neon bulb as the indicator, and a mounting plate. It is commonly used in equipment control panels. The DPST switch is used to control the circuit and can cause either an energised or de-energised state. When the switch is in the energised state, it will connect one end of the neon bulb to the power input and the other end to the ground. This causes the bulb to light up and thus indicating the energised state. When the switch is in the de-energised state, the connection will be cut and the bulb will not be able to light up, thus indicating the de-energised state. Pilot lights are another type of panel indicators and can be found in many industrial electrical systems and consumer applications. Pilot lights are typically used to indicate system status, signal alarms and provide instant visual feedback to operators. Generally, pilot lights consist of a miniature bulb or LED light, a base mounting fixture and a switch. They can be connected directly to the power supply or controlled electronically. When the switch is triggered, either manually or through an automation system, the connected power supply is connected to the bulb or LED. This causes the indicator to light up. Colors and intensities can be determined by choosing the right type of indicator and power supply. For example, a green LED pilot light can be used to indicate the ready state and a red bulb can be used to indicate the alarm state. <h2><strong>Conclusion</strong></h2>Panel indicators, pilot lights and 91-NWA120-CAO are all electrical components used for signaling purposes. They are widely used in various applications, such as industrial automation, consumer electronics, and more. The 91-NWA120-CAO is a double-pole single-throw switch and a neon bulb used to indicate an energised or de-energised state. Pilot lights are miniature bulbs or LED lights typically used to indicate system status, signal alarms and provide visual feedback to operators.
