Sealed Tiny Pushbutton Switches

img description

Image shown represents the product series and may not indicate the actual part number

The EP series of sealed tiny pushbutton switches from C&K are selected to power applications in the telecommunications and networking industry. The EP’s snap-fitting actuator accepts standard caps, and is sealed to protect against solder and cleaning processes – helping ensure it can withstand any harsh environment. Available in thru-hole and surface mount models, C&K’s EP switches are also RoHS compliant.
