Key switch |
摘要 |
A key switch comprises a casing, at least one key slide guided in the casing against the force of a spring and at least one J-shaped leaf spring having a long spring arm and a short spring arm connected to the long arm by a curved intermediate part, the leaf spring being clamped to assume a unilateral curvature between two abutments, one fixed and the other moveable, the leaf spring having the free end of its long spring arm supported in a first abutment in the key slide and its curved intermediate part in a second abutment formed in a fixed contact member provided in the casing. For providing a minimum space the leaf spring is mounted parallel to the sliding direction in an elongated recess of the key slide.
