General information

1/2″ Switches (R)

When the nominal switching temperature is reached, the contacts open through a snapping of a thermo-bimetal snap-disc whose temperature has been dimensioned through embossing, aging, etc. After the appropriate cooling, the bimetal disc automatically snaps into its previous position, and closes the circuit again, or the interruption will continue until a manual reset is performed. Half-pin switches can also be supplied with a NO contact function.

These R-types are ideal on-switches with a high temperature sensitivity for applications in household appliances, railway technology, electronic devices, mechanical Engineering.
