Brake light switch -OEM QUALITY- Vespa PV125, ET3, PX80, PX125, PX150, PX200 (models without indicators) - NCC (blue/black)

All Vespa brake light switches are operated when installed. This means that the pedal already presses on the spring-loaded actuating pin when not in use. Therefore we always name the function of the switches the same way they work when installed.
However, if you hold the switch loosely in your hand, the circuit diagram is exactly the other way round as we have specified.
