General information

Open temperature switches / current switches or time switches (A / D series)

They are characterized by their variable function: in addition to the automatic reset, these switches offer the possibility to perform a manual reset, and an electrical self-retaining.

In particular, the non-housed variants can be operated in combination with a ventilation system in the superheated state. When the cooling airflow is interrupted (through a blockage of the fan motor or a covering of the device), the switch triggers very rapidly and prevents damage.

Typical applications include a wide range of domestic appliances (dryers, cooking appliances, heaters, etc.), automotive and electronic applications. There are numerous connection options: Plug, rivet, screw, welding or soldering Connections.
