Title:
NEW MAGNETIC PROXIMITY SWITCH
Document Type and Number:
WIPO Patent Application WO/2015/196630
Kind Code:
A1
Abstract:
A new magnetic proximity switch, comprising a shell (1), wherein a moving magnet (2) which can move up and down is provided on an upper part within the shell (1), a first terminal strip (6) and a second terminal strip (7) are fixedly provided at the bottom within the shell (1) in parallel left and right, a static contact (71) is provided on the second terminal strip (7), an elastic piece (4) is provided on the first terminal strip (6), a moving contact (41) is provided at an outer end of the elastic piece (4), and the moving contact (41) and the static contact (71) are provided correspondingly; and an assistant rod (3) is provided at a middle part within the shell (1), the assistant rod (3) is swingably provided within the shell (1), an assistant portion (33) is provided at an inner end of the assistant rod (3), a limiting mechanism is provided between the assistant rod (3) and the shell (1), the moving magnet (2) and the assistant portion (33) are provided correspondingly, an elastic tongue piece (5) is provided on the elastic piece (4), and an outer end of the elastic tongue piece (5) is provided against the assistant portion (33). The structural arrangement of the switch is reasonable, and solves the existing technical problem that metal fatigue and arcing occur easily by effectively controlling an acting force borne by the elastic tongue piece with the spacing mechanism.
