ABSTRACT:
An adjuster for a throttle device of an internal combustion engine in which a switch tappet is guided in an actuating tappet in such a way that external forces are not exerted upon it, which prevents any problems to the switch performance. The adjuster is embodied such that the switch performance is easily adjustable and is protected against external influences. The adjuster has an actuating tappet, formed of a guide body and a switch socket, in which a switch is disposed. The switch socket is displaceably supported in the guide body with a guide shoulder counter to the force of a restoring spring and it guides a switch tappet, which is aligned with the switch and which is threaded to a variable depth into the switch socket in order to adjust the switch point. Any external forces act upon an actuating body supported in the switch socket. The adjuster is used to adjust the position of a throttle device in the intake tube of an engine.
