The push to test pilot light is used in applications where the pilot light is:

• A. Rarely needed.
• B. A neon bulb.
• C. Used in DC applications.
• D. In constant use.

Answer: (A)

Push-to-test pilot lights are used when the pilot is not needed all the time. The momentary push energizes the ignition circuit to light the pilot so you can verify that the gas supply, ignition, and flame-sensing (thermocouple) are working. Once you release, the system returns to its standby state and the pilot is off, saving energy and reducing wear. This approach makes sense in applications where the pilot is rarely required, because it provides a quick, on-demand check without keeping a flame burning constantly.
