ABSTRACT:
An engine throttle valve position detector has a throttle switch formed by a rotary detector member rotatable with the engine throttle valve, a single stationary contact and a single movable contact movable by a guide groove in the rotary detector member into and out of electrical contact with the stationary contact. The stationary and movable contacts are contacted together when the throttle valve is in both fully-closed and fully-open positions, to thereby emit electric signals to an electric control unit which compares the signals with another signal representative of the engine operating condition, such as engine intake air per engine revolution or manifold vacuum, to judge one of the throttle valve fully closed and fully-open positions.
