Final answer:

Lighted toggle switches use a neon lamp that illuminates in the on position when an electric current excites neon gas, emitting a characteristic red glow or other colors through different gases or glass.

Step-by-step explanation:

  • Lighted handle toggle switches utilize a neon lamp that is illuminated when the switch is in the on position.
  • Neon lamps and signs operate by passing an electric spark through a tube containing neon at low pressure, which generates the familiar red glow associated with neon.
  • The color of the light can be varied by either mixing other gases such as argon or mercury vapor with the neon or by using colored glass tubes.
  • This phenomenon is based on the principle that electricity excites electrons in the gas atoms, and as the electrons return to a lower energy state, they emit light.
  • While many neon lights do not contain neon, the red-orange glow is characteristic of true neon gas discharge tubes, with other colors often being produced by different gases or glass colors.

Final answer:

The neon lamp in a lighted handle toggle switch is illuminated when the switch is in the on position. Neon signs, often misunderstood as only containing neon gas, can emit various colors depending on the gas or the color of the glass used in the tube.

Step-by-step explanation:

Lighted handle toggle switches utilize a neon lamp that is illuminated when the switch is in the on position. These switches are designed to indicate visually when a circuit is active. Neon lamps are a type of gas discharge tube, which light up when an electric spark passes through neon gas at low pressure, producing a characteristic red glow. However, using different gases such as argon or mercury vapor, or colored glass tubes, can change the light's color.

Neon lights are often used in signage and art installations, known for their ability to emit bright, colorful light when electrified. The color change mechanism in neon lighting involves exciting the electrons in the gas atoms, which then emit light as they return to a lower energy state. While many signs are called "neon," the term generally refers to the type of illumination rather than the specific gas used, as many of these lights do not contain actual neon gas.
