Abstract
A switch apparatus includes: a button key being displaceably supported in a pressing direction; a displacement portion being displaced in the pressing direction in interlocking relation to the button key; and a switch being disposed on a downstream side in the pressing direction of the button key. The switch is operable a switching action by being pressed by the displacement portion when the button key is operated by pressing. The displacement portion deviates from the button key with respect to the pressing direction.

A switch apparatus comprising:
- a button key displaceably supported in a pressing direction;
- a displacement portion in interlocking relation to the button key and configured to be displaced in the pressing direction;
- a switch configured to be pressed by the displacement portion when the button key is operated by pressing;
- and
- a key frame disposed to intersect the pressing direction of the button key, and the key frame supporting an outer edge of the button key;
- wherein the displacement portion is on the key frame and at a position offset from the button key with respect to the pressing direction, and the key frame as a first notch for separating the button key and the displacement portion.
