PURPOSE:To make the contact gap between contact spring pieces or the contact pressure constant and make the separation operating force of contacts constant by pressing and bending the contact spring pieces and supporting them in the energized state at the preset positions. CONSTITUTION:In a normally opened type, contact spring pieces 2a, 2b are pressed and bent and supported in the energized state at the preset positions P1, P2, in a normally closed type, when the contact spring piece 2e is pressed and bent, contacts (a), (b) are pressed, and the contact spring piece 2b is bent and supported in the energized state at the preset position P1. In the normally opened type, when an operating piece 3 is pressed, the contact spring piece 2a is bent, and its contact (a) is brought into contact by pressure with the contact (b) of the contact spring piece 2b. In the normally closed type, the contact (a) of the contact spring piece 2a normally bent end energized and supported at the preset position P1 is in contact by pressure with the contact (b) and the contact spring piece 2b is bent and energized and supported, and when the operating piece 3 is pressed, the contact spring piece 2b is bent, and the contacts (a), (b) are separated. The contact gap and the operating force are thereby made constant. |
