The STKLBK is a microminiature SPDT key switch featuring a single changeover contact arrangement with non-shorting mode of operation. It is designed for low-level switching with a maximum switching power of 240 mW DC and maximum switching voltage of 24 V DC, supporting a maximum switching current of 10 mA DC. The switch offers both momentary and push-push latching function options, with an operating force of 1.5 ± 0.5 N, total travel of 3 mm, and switching travel of 1.5 mm. It features high reliability with an operating life of =5×108 operations for momentary mode and =5×105 operations for push-push mode, along with excellent contact resistance characteristics and RoHS compliance. The STKLBK is ideal for medical instrumentation, industrial electronics, and audio electronics applications where compact size, reliability, and precise switching are required.
