PTS645TL50 is a subminiature tactile switch from the C&K PTS Series designed for cost-effective switching applications in consumer products, instrumentation, computer products, and hand-held devices. This 6 x 6 mm model features a 130 g typical operating force with a black actuator and a height dimension of 0.197 inches (5.0 mm), and includes an ESD pin for electrostatic discharge protection. The switch is rated for 50 mA at 12 V DC with a contact resistance of 100 milliohms maximum and an insulation resistance of 10? O minimum, delivering 100,000 mechanical and electrical operations over its lifetime. Operating across a temperature range of -10°C to 60°C with dielectric strength of 250 V AC minimum, the PTS645TL50 combines long-life contact design with multiple actuation force options, making it ideal for reliable switching in compact electronic assemblies.
