C&K Components has developed a momentary power push-button switch that can handle 240V line power directly as a main switch.
The PWR Series push-button switch enables single step processing onto SMD boards, and can latch a larger-sized relay than a typical tactile switch is designed to handle. The momentary, single-pole single throw (SPST) PWR Series switch delivers an extended operating life of 100,000 mechanical cycles and is surface-mount solder process compatible.
The PWR Series push-button switches accommodate a voltage range of 20VAC to 250VAC, and a current range of 10mA to 2A, with a maximum contact resistance of 100mOhms. The PWR Series handles inrush loads up to 7A. The nominal operating force is 7N and operating travel is 1.0mm. Operating temperature ranges from -40ºC to +85ºC.
The PWR Series switches are available in tape-and-reel or tube packaging. The SMD PWR Series switches are ideal for white good and appliance main power, particularly in dishwashers, eliminating the need for a separate panel-mount power switch and wire harness.
