Brochure: The best way to switch and dim LED lighting
Two contacts for all switching cases: Tungsten pre-contact
High currents require special contacts. Next to silver tin oxide (AgSnO2), Theben uses a combination of two contacts that close after one-another: the tungsten pre-contact.
The leading contacts comprise high-Ohm and highly-resistant tungsten. It captures the starting current and limits it at the same time. The low-Ohm main contact remains unloaded from the switching peaks in such a manner.
Overview: switching units with tungsten pre-contact
Theben uses relays with tungsten pre-contact with many digital time switches, astronomical time switches, several motion detectors and many presence detectors.
Digital time switch with weekly program
Most digital time switches with a width of 1 TE (Does not apply: TR 608 top2 S) are equipped with a tungsten pre-contact that protects the switching relay and takes over the capacitive switching load.
TR 609 top2 S
- Tungsten pre-contact
- LED switching capacity: < 2 W: 55 W, 2-8 W: 180 W, > 8 W: 200 W
