Claims

[Scope of utility model registration request]

A base plate, a rotary plate provided with a gap on the base plate and rotating integrally with the slot valve, a cam groove formed with a predetermined groove shape on the upper surface side of the rotary plate, and the cam groove. first and second contact plates that are slidably engaged with the rotary plate and repeatedly turn on and off as the rotary plate rotates; a potentiometer that detects the rotational position of the rotary plate; A predetermined rotational position of the rotary plate is detected based on ON and OFF signals output from the first and second contact plates, and the detected value of the potentiometer is corrected at the predetermined rotational position. A throttle valve switch device comprising a detected value correction means.
