Abstract

The invention provides a switching-on/off structure of a lamp and an indicator lamp. The switching-on/off structure comprises button assemblies arranged in pairs, connecting assemblies which are arranged among connecting parts for each pair of button assemblies and are connected in series with a light source control circuit board and elastic elements arranged between the connecting assemblies andthe connecting parts, wherein when contact parts of the button assemblies arranged in pairs are pressed in contact and are electrically switched on, the connecting parts of the button assemblies are respectively switched on with both ends of the connecting assemblies by the elastic elements. The invention realizes the switching-on between the elastic elements and the connecting assemblies by using external conduction components and simultaneously pressing the contact parts of the button assemblies, and realizes the switching-on of the lamp by forming the connecting assemblies and the light source control circuit board into a power supply circuit. The switching-on/off structure ensures that the lamp can be switched on/off only by means of the external conduction components, thereby avoiding potential safety hazard of a directly-opened switching-on/off structure from abnormal switching-on/off under misoperation conditions. The indicator lamp using the switching-on/off structure ensures the safety identification effect.
