SWITCH RTH D01 / RTH D01-3

The RTH D01 / RT D01-3 is a series of rotary switches designed for home appliances, heating and ventilation systems, and industrial equipment with medium-scale functional diagrams.

In the RTH D01 / RT D01-3 series, the control lever determines the device’s operating mode by closing its assigned contact group in each position, and this state persists until the next stage. The series is manufactured with a 1-3 circuit, and the number of positions can be configured from 1 to 5 or more. This configuration provides a balanced solution for applications where multiple circuits must be controlled from a single control unit but do not require an extensive programming scheme. In devices where it is used as a program selector switch, the stage sequence is configured according to the manufacturer’s function list; the pin material can be selected as plastic or metal.

The electrical ratings are specified as 16(4) A and 18(5) A at 250 V; this corresponds to switching 16 A to 18 A resistive loads and 4 A to 5 A inductive loads. The T125 temperature class and the glass-fiber-reinforced PA66 GF25 V0 housing ensure stable operation of the switch in the device’s hot zones. A 10,000-cycle lifespan meets the expected service life in regularly controlled applications. Connections are made via 6.3 x 0.80 mm tab terminals, and due to the IP00 protection rating, installation is performed inside the device’s enclosed housing.

The RTH D01 / RTH D01-3 ensures safe switching in continuously operating equipment with glow wire temperatures of 850 / 750 °C and a T125 temperature class.

The series is designed and tested in accordance with the requirements of the EN 61058-1 standard, which covers switches used in household and similar appliances. The 850 / 750 °C glowing wire test (GWIT) results reveal the insulation material’s behavior in the connection area when exposed to ignition; they indicate that a Class T125 product can operate at ambient temperatures up to 125 °C. The 10,000-cycle life rating confirms the rotary switch’s durability under repeated operation at the specified load. In accordance with the IP00 protection rating, installation must be performed inside a sealed device enclosure.
