C&K launches SSW series detect switch for automotive and industrial safety applications

Electromechanical switches may seem like a quaint form of
technology in the era of machine learning and self-driving automobiles, but the
truth is that switches are still ubiquitous in all manner of electrical devices
and systems. C&K recently developed the SSW series detect switch,
targeting automotive and industrial safety applications.

 The double-pole/double-throw
(DPDT) switch is IP67 sealed to prevent long-term erosion from liquid or dust
particles, and can withstand operating temperatures ranging from -40°C
to 85°C,
making it particularly well-suited for harsher operational environments. It
offers switching travel compatibility with existing products on the market,
making it easy to replace switch devices in established designs.

The SSW detect switch also provides low-level switching (5 V
– 1 mA) and rapid switching times (less than 15 ms), as well as long-term
product life (approx. 300,000 electrical cycles), even when operating in
extreme conditions. Other key features include built-in redundancy, self-failure detection and lack
of bi-stability with controlled switching time.

Sealed switches offer robust protection from the environment,
which is critical in industrial and automotive applications. A switch that is
IP67 sealed is particularly resistant to both dust and water. Ingress
Protection (the “IP” in IP67) is just one of the highest levels of several
rating levels defined by the International Electrochemical Commission (IEC), an
organization with global scope responsible for electronic device standards.

The IP sealing rating identifies both the ingress protection
against solid particulates, or dust, and water. The first digit in the IP
rating identifies the size of the particulate being protected against. At level
0, protection against objects larger than 50 mm is specified. Protection levels
from 2 to 4 protect against objects from 12.5 mm, 2.5 mm and 1 mm,
respectively. Level 5 specifies protection sufficient to prevent significant
damage, while level 6 is totally protected against dust. The second digit in
the IP rating indicates the level of protection against water. Levels 1 through
6 specify protection from light rain up to high-powered water jets. A level 7
rating specifies protection for up to 1 m of immersion for up to 30 min. Make
sure you carefully match the rating of your switch to your target environment.
