Abrégé

A magnetic proximity sensor assembly 10. The magnetic proximity sensor assembly 10 comprises a switch assembly 12 received in a blind bore 14 of a body tube 16. The switch assembly 12 comprises a magnetic assembly 18 moveable in the blind bore 14. The switch assembly 12 comprises an operator 42 which extends from the magnetic assembly 18 and serves as a drive for a moving contact 44 positioned between a first contact 46 and a second contact 48. The magnetic assembly 18 comprises a primary magnet 20 and a biasing magnet 22. The switch assembly 12 comprises a centre magnet 26 interposed between the primary magnet 20 and the biasing magnet 22. The blind bore 14 has a uniform bore diameter. The magnetic proximity sensor assembly 10 comprises a sleeve 28 in the blind bore 14 contacting the closed end 30 of the blind bore 14. The switch assembly 12 is seated on the sleeve 28 such that the primary magnet 20 of the magnetic assembly 18 is surrounded by the sleeve 28.
