Which of the following statements is true about a push-to-test light?

The statement regarding the push-to-test light being true is that it has a unique testing mechanism. The push-to-test function allows users to check that the light is operational and verify that it is connected properly within the motor control system. When the button is pressed, the lamp illuminates, providing a quick visual confirmation that the light is functioning as expected. This feature is particularly useful for maintenance and troubleshooting, ensuring that the indicator is reliably indicating the status of the system.

This unique mechanism is what distinguishes push-to-test lights from standard indicator lamps, which illuminate under normal operating conditions but do not provide a means for direct testing. The ability to test the light independently makes the push-to-test light valuable in applications where the reliability of indicators is critical for safety or performance monitoring.
