Japanese Patent JP7005265
Kind Code:
B2
Abstract:
To save the space while securing sufficient stroke of operation means.SOLUTION: A sheet plate 307 is placed with the depression direction of a release button 114 as the thickness direction. A first electrical contact piece 305 has an L-shaped extension part 305c in cantilever state. When the release button 114 is depressed, the extension part 305c is driven and deformed elastically to bend downward, and when the first electrical contact piece 305 comes into contact with a second electrical contact piece 304, turn ON of a first stage switch is detected. Furthermore, when the second electrical contact piece 304 comes into contact with a third electrical contact piece 302, in a state where the first electrical contact piece 305 is in contact with the second electrical contact piece 304, turn ON of a second stage switch is detected. The sheet plate 307 and the extension part 305c are placed at substantially parallel positions, and the extension part 305c exists almost entirely within the thickness range of the sheet plate 307 in the thickness direction thereof.SELECTED DRAWING: Figure 3
