Title: Method for determining contact closing behavior of a bifurcated cantilever spring
IPC: H04Q1/20
Filed: 1970-03-06
Abstract: The contact closing behaviour of a bifurcated cantilever-spring contact set, having two arms each carrying a contact to co-operate with a respective further contact, such as used in a telephone relay, is determined by applying alternating voltage between the spring and further contacts and using a search coil at a given position to monitor the field produced by the current that flows when the pairs of co-operating contacts are closing or supposedly closed. The given position is closer to one arm than the other. The coil 6 may be disposed to one side of the spring 1. If current flows only in the more distant arm a relatively weak signal will be detected, if it flows in both arms a stronger signal will be obtained, while if it flows only in the nearer arm a still stronger signal is obtained. The contacts may be held in their supposedly closed condition and the test conducted to ensure that both contacts are indeed closed, or a closing operation may be initiated, the test being used to determine whether the contacts close simultaneously.
