ROTARY SWITCH RT 401 / RT 801

The RT 401 / RT 801 is a series of rotary switches that can be configured for up to 3 circuits and provide step-by-step control for home appliances, heating and ventilation systems, and industrial equipment.

In the RT 401 / RT 801 series, each stage activates its own defined contact combination, and the selection is maintained until a new position is selected. The series is manufactured with 1–3 circuits; the number of positions can be customized from 1 to 5 or more. This design is suitable for medium-scale functional schematics where several independent circuits must be controlled from a single control unit. In devices where the program selector is positioned as a switch, the stage configuration is determined by the manufacturer’s operating modes; the pin material is selected as either plastic or metal depending on the button design.

The Series operates at 250 V with current ratings of 16(4) A and 18(5) A; that is, it switches resistive loads of 16 A to 18 A and inductive loads of 4 A to 5 A. The PA66 GF25 housing, rated T125 for temperature class and V0 for flame class, allows the switch to be used in hot spots within the device. A switching life of 10,000 cycles meets the expected service life in regularly controlled applications. Connections are made via 6.3 x 0.80 mm tab terminals; due to its IP00 protection rating, the product is unprotected against the ingress of solid objects and water and must be mounted inside the device’s enclosed housing.

RT 401 / RT 801, 850 / 750 °C glow wire values and 125 °C ambient temperature resistance meet the safety requirements for use inside the device.

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 demonstrate the insulation material’s resistance to ignition, while the T125 classification indicates its ability to operate at ambient temperatures up to 125 °C. The 10,000-cycle life rating indicates the rotary switch’s ability to withstand repeated operation under the specified load. In accordance with the IP00 protection class, the product is designed for use inside an enclosed device housing.
