Tactile switches with SPDT functionality provide superior safety
The KSC DCT switches from Littelfuse provide robust operation and a long lifetime in automotive, industrial and other applications which require high reliability and the ability to detect fault conditions.
The KSC dual circuit technology (DCT) series products from Littelfuse are IP67-rated momentary-action switches which give users a positive, adaptable tactile response.
The KSC DCT series is the first tactile switch to offer single-pole double-throw functionality in a small 6.2 mm x 6.2 mm x 5.2 mm enclosure.
The KSC DCT switches’ dual-circuit technology provides advanced safety functionality in a small form factor. The switch allows precise monitoring of the status of an electro-mechanical tactile switch, even when the switch is not in use, helping the system to distinguish a silent signal from a device malfunction.
This active failure verification enabled by the switch’s single-pole double-throw configuration means that the system can detect faults such as an unwanted door opening.
