The

R2/R3

temperature switches are very reliable bimetal

technology components, offering a long life time.The
normally closed contacts open when reaching the pre-
defined temperature by snapping of a bimetal disc.
Temperature setting is defined through conditioning
(aging, stamping, ...) of the disc. After a corresponding
cooling down, the bimetal disc snaps back to the original
position and closes the current circuit again (R2-series)
or remains in open position until manually resetted (R3-
series). These R-types are perfect

surface mount compo-

nents,

offering high temperature sensibility and can be

used in a wide range of white goods, automotive techno-
logy, mechanical engineering, kitchen appliances.

Characteristics:

•

ceramic housing for high temperatures available

•

small tolerances of 3 K possible

•

various caps available

•

terminals in various dimensions and

bending angles

•

short switching and contact bounce
