C&K Components (Newton, MA) has developed the new PTS 530 Series ultra-low- profile top actuated SMT switch. Utilizing C&K’s unique symbol line identification system, design engineers can quickly and easily identify actuation force ratings. The marking system defines the model number and actuation force on the switch itself, which eliminates the need for designers to rely on confusing schematics. The PTS 530 Series SMT switch is only 4.5mm x 4.5mm with a 0.55mm thickness (0.65 mm for high force versions) and features a lifespan of up to 1,000,000 operations. The momentary action, top actuated SMT switch features a gullwing or J-type terminal and can be soldered via infrared reflow in accordance with the IEC61760-1 standard. The PTS 530 Series switches are available in six different varieties, dependent on actuation force. The PTS 530 Series SMT switch has a maximum voltage of 12VDC. The operating temperature range is -40°C to +85°C.
