Panel indicators, pilot lights are the most widely used operator interface components. In order to meet different user application needs, a variety of different types of operators and indicators have been developed. The 2191QL5-12V is a type of the selector switch commonly used in industrial automation. It is used for machine control applications in various industry sectors including engineering machinery, industrial control, food processing, and chemical industry.

The 2191QL5-12V selector switch is composed of a three-position switch and a 12V, 5-position indicator lamp. The switch is constructed with a rotating knob, which allows the operator to select between three different positions. The switch is protected by a cover to prevent dust, dirt or other debris from entering the selector switch. When opened, a small window on the cover allows visibility of the indicator lamp, which will indicate the current position of the switch.

The working principle of the 2191QL5-12V selector switch is fairly simple. Power is supplied through the two terminals on the back of the switch. When the switch is turned on, the current flows through one of the two terminals connected to the switch. Depending on which position the switch is set to, the current will be redirected to either the \'On\' or \'Off\' terminal. This will cause the indicator light on the switch to illuminate, signaling that the switch is in the corresponding position.

The 2191QL5-12V selector switch is typically used in industrial control applications, where it is important to maintain a reliable and consistent position of the switch. The switch is highly resistant to wear and tear, and its sturdy construction ensures long-term reliability. The switch is designed to operate in a wide range of temperatures and under vibration, making it suitable for a variety of environments. The switch is also designed to be waterproof, allowing it to be safely operated in wet environments.

The 2191QL5-12V selector switch is used in a wide range of applications such as process control, machine tooling, HVAC/R systems, and power distribution systems. It is often used in industrial control panels and process control systems to set the desired operational state of the system. The indicator model of the 2191QL5-12V selector switch provides visual feedback about the switch position and can be used as a troubleshooting aid. The switch is easy to install and operate and requires minimal maintenance.

The 2191QL5-12V selector switch is a reliable and durable solution for industrial automation applications. It is easy to install and provides a visual indication of the current switch position. The switch is highly resistant to dust, dirt, and vibration, making it suitable for harsh industrial environments. It is a cost-effective solution for a wide range of applications and is sure to provide reliable service for years to come.
