Abstract: The present disclosure describes a mechanical switch (10) to switch a light emitting diode (LED) or another load. The mechanical switch (10) includes a rocker (1) pivotally mounted with respect to a first pivot point (PI), at least one fixed electrical contact (4), and a blade (2) pivotally mounted with respect to a second pivot point (P2). The blade (2) has an electrical contact (3) connectable with the at least one fixed electrical contact (4). The rocker (1) and the blade are mechanically coupled to each other via a cam (5), a plunger and a follower (6).
