Abstract
1,136,234. Magnetic switches. CRAWLEY ENG. DEVELOPMENTS Ltd. 11 March, 1966 [24 March, 1965], No. 12472/65. Heading H1N. A sealed magnetic contact unit 20 operated by movement of a permanent magnet 29 on a pivoted float arm 27 is mounted in a non- magnetic probe 16 which also encloses a thermostatic or other condition responsive switch 19. The switch 19 may be in series with the contact unit 20 and mounted so that the unit 20 is operated when the switch 19 is still below the level of liquid which moves the float. The contacts of the unit are biased to the closed position by a permanent magnet 24 held on the unit 20 by a shrunk-on plastics sleeve 25.
