The SI400 consists of an end switch (normally closed contact / switch) and a magnetic switch contact (actuator) which is mounted either on the floor stand R472 with the fixing device SI472 or alternatively on the telescopic stand R474 with the fixing device SI474. The stirring unit RW47 can only be switched on through the SI400, when the agitator is adjusted to the user-selected height within the mixing vessel. The power supply to the RW47 automatically shuts off if the stirring unit is lifted above the selected height.
