I see three terminals but there may be more. I cannot see which terminals are connected to the switch and which terminals are connected to the LED. I cannot tell if there is a resistor in series with the LED or what its value is. I do not know the polarity of the LED. I do not know whether the switch is in the closed or open state. I do not know whether the switch is SPST, DPST, SPDT, or something else. I do not know whether the switch has a center position. I do not know whether the switch has a spring return.
Other than that, it is a great photograph.
