Document Type and Number:
Japanese Patent JPH0714254
Kind Code:
B2
Abstract:
A relay includes a movable element having first and second portions separated from each other. The first portion can be moved between a first stable position corresponding to a state where contacts are closed and a second stable position corresponding to a state where the contacts are opened while abutting against resilient plates. The second portion can push the first portion so that the first portion is moved from the second stable position to the first stable position by application of external force. The second portion is always urged to go away from the first portion by a spring. The first and second portions are disposed to be separated from each other by a distance corresponding to a stroke of the first portion when the first portion is positioned at the first stable position. The first portion of the movable element is moved from the first stable position to the second stable position by a magnetic force of a solenoid coil when sensor terminals are electrically connected to each other.
