发明名称 Electric sauna heater
摘要 This invention relates to an electric sauna heater comprising one or more heating resistors (1, 2) and means (3, 4) such as a time switch (3) for controlling the supply of electric power to the heating resistors, the time switch (3) comprising at least three inputs (A, B, C) the first (A) of which is connected to a first time switch contact 3A), the second (B) to a second time switch contact (3B) and the third (C) to a first terminal in a driving motor (M) for the time switch while a second terminal is connected to a counter contact (b) in the second contact (3B). In the invention, in order that the time switch could therefore be connected to two different operating voltages, a resistor (R) is connected between the third input (C) of the time switch (3) and a counter contact (a) in the first contact (3A).
