A neutral start switch has a base on which stationary contacts are arranged and a rotor on which movable contacts capable of contacting the stationary contacts are disposed. The stationary contacts include reverse lamp contacts connected to a reverse lamp lighting circuit, position stationary contacts connected to a position signal circuit provided in an electronic control device, and starter stationary contacts connected to a starter motor driving circuit. The contacts are arranged so that contact portions of the movable contacts that contact the reverse lamp stationary contacts are different from contact portions of the movable contacts that contact the other stationary contacts, thereby preventing carbonized powder produced by spark at the time of the closure and opening of the reverse lamp contacts from causing a contact failure of another contact.

Neutral start switch

An electronically controlled automatic transmission control system for controlling an automatic transmission for a vehicle, comprising an electronic controller which receives functions on the basis of input signals corresponding to the running conditions of the vehicle to control a hydraulic controller including a fluid pressure source, shift control valves for changing over the connection of the fluid pressure source to the respective hydraulic servomotors of frictional engaging mechanisms which controls the operation of the components of a gear train included in the automatic transmission, solenoid valves adapted to be controlled by the electronic controller to change input signal pressures to the shift control valves and a manual selector valve having a spool capable of moving through predetermined set positions corresponding to the shift positions of the manual shift lever of the vehicle, in which the input signal pressure is supplied to one of the shift control valves, namely, 1-2 shift control valve, when the spool of the manual selector valve is shifted to a position corresponding to the neutral position, in order to improve the delayed operation of the automatic transmission in shifting the automatic transmission from the neutral or the parking position to the drive position.
