The invention relates to an electrical switch (1) having a housing (2), having a contact system (5) which is located in the housing (2) and having a moving operating element (6), which projects out of the housing (2), for switching over the contact system (5) between two switching positions. The operating element (6) is operatively connected to a guide cam (13) in the manner of a switching crossing, in which a pin (14) engages, in such a way that the operating element (6) can be locked in at least one of the switching positions as a result of the interaction between the pin (14) and guide cam (13). A movement means (15) for the pin (14) is arranged in the housing (2). As a result, the pin (14) can be moved into and/or out of the guide cam (13), specifically particularly in such a way that the switch (1) can be switched from the lockable switching position to the other switching position.
