Electric switching element, in particular for attachment to the brake pedal of a motor vehicle

摘要

The electric switching element (on/off switch) (1) is provided for attachment to the brake pedal of a motor vehicle for switching on the vehicle's brake lights (34) by actuating the brake pedal. It consists of a housing (2, 3) which comprises a switch (12, 20) with a movable contact (12) which can be adjusted by means of a displaceable pressure rod (6) which is actuated by the brake pedal. It is connected to an input (31) which can be permanently connected to a power supply source (V) and to a first output (32) which can be connected to the brake lights (34) via the switch (12, 20), and a second output (33) which can be connected to an auxiliary circuit (30). The switching element comprises a rapidly switching, electronic circuit (36) which is coupled to the switch (12, 20) and is constructed in such a way that it can detect the application of an electric signal from the power supply source (V) to the first output (32) or to the second output (33) when this switch (12, 20) is closed or opened, and is capable of performing the switching of the signal from one of the two aforesaid outputs to the other more quickly than the switching process of the aforesaid switch (12, 20). <IMAGE>
