Designers can quickly identify actuation force ratings thanks to a symbol line identification system developed by C&K Components, which was integrated into its PTS 530 series top actuated switch. The marking system defines the model number and actuation force on the switch itself, which eliminates having to rely on schematics. The switch measures a mere 4.5 by 4.5 mm and is 0.55 mm thick (0.65 mm for high-force versions), saving board space. It has a lifespan of up to 1 million operations. The momentary action switch features a gullwing or J-type terminal, and can be soldered via infrared reflow in accordance with IEC61760-1. Maximum voltage is 12 V dc; operating temperature ranges from −40 to +85°C. Six different varieties are available, depending on actuation force. The PTS 530 is designed for use in rugged consumer devices.
