Abstract (en)
[origin: EP0017640A2] 1. A mercury-wetted reed switch of the break-before-make type comprising a capsule (10) including a pair of contacts and a movable magnetic armature (1) consisting of a beam (11) extending axially inside the capsule (10) and having two pole ends (12, 13) capable of alternately contacting engagement with a respective contact (2, 3) when the armature (1) is pivoting, characterized by a helicoidal spring (5) extending axially inside the capsule (10) and being attached at its central portion to a cylindrical annular electrode (6) which extends around it and which is fixedly positioned inside the capsule, said spring (5) working in flexion mode, and by the beam (11) of the armature (1) extending inside the spring (5) and being suspended to the ends of said spring at two points (51, 52) symmetrically situated with respect to the transversal axis of said beam (11), the pole ends (12, 13) of the armature projecting beyond said ends of the spring (5), whereby said spring is capable of storing mechanical energy.
