The electrical switch comprises a rotatable carriage having two contractors for engaging a series of contact points. Each contactor comprises a sector-shaped portion for engaging the contact points, and a point portion spaced inwardly from the sector-shaped portion. In the case of one contactor, the point portion is engageable with a contact sector on the insulating board which carries the contact points. In the case of the other contactor, the point portion rides along the insulating board. The switch may be employed in a turn signal switching system comprising left and right-hand signal lamps. A first battery feed wire is connected to the stationary contact sector through a flasher. The contactors are movable to four positions, comprising an off position, a flash left position, a flash all position and a flash right position. The first contactor establishes the connections between the contact sector and the contact points for flashing the left signal lamps, all signal lamps, and the right signal lamps. A second battery feed wire is connected to a pair of contact points through a dimming resistor. These contact points are engageable by the second contactor, which establishes connections for lighting the right lamp dimly when the left lamp is flashing, while lighting the left lamp dimly when the right lamp is flashing. Other modified switches and turn signal switching systems are also disclosed.
