A line switch for twin-wire cable comprises a switch housing of one-piece clamshell-type construction, a pair of terminals mounted within the housing, a leaf spring having a pair of movable contact portions within the housing, and an armature for moving the movable contact portions between a closed and an open position. A cover portion and a body portion of the switch housing are hinged together along a common longitudinal edge which serves as a living hinge. The housing has a channel in which an open elongated electrical wire is laid, and a piercing projection integral with a stationary contact portion of the terminals is operative to pierce through and electromechanically engage the open wire when the cover portion is pivoted to close the body portion in an assembled position. Snap-action legs maintain the cover and body portions in the assembled position.
