PURPOSE:To prevent simultaneous separation of contact pieces by a housing so as to lengthen life and improve high frequency response characteristics and contact reliability by dividing the contact parts of contact pieces into plural segments different in natural frequency. CONSTITUTION:In the contact structure that the contact parts of both contact pieces are contacted or separated by driving one hand of the contact pieces opposed to each other in the plate thickness direction, respective contact parts 2 and 6 of fixed and movable contact pieces 1 and 5 are divided into plural segments 3 and 7. Respective natural frequency of these plural segments 3 and 7 are so designed as to be different, so they oscillate in oscillation synchronism different for each, and simultaneous separation by a housing is prevented. As a result, it becomes contact structure having long life and high frequency responsiveness and high reliability. |
