Abstract
952,529. Fluid actuation of switches. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 25, 1962 [Dec. 15, 1961], No. 44966/61. Heading H2B. [Also in Division G1] A float-controlled contact arrangement comprises a metal cylinder 13 open at its lower end and depending from a closure cap 12 for the neck of a liquid reservoir, and a hollow float 18 open at its lower end with a rod 19 passing through a hole 21 in an insulating plug 14. As the level of the liquid falls, the float 18 lowers and part 22 of the rod 19 engages a metal strip 17 in the plug 14, to complete a circuit to a lamp 26, the float 18 and earthed cylinder 13 being connected by a wire 20. A gaseous discharge lamp may be used in the circuit, Figs. 2 and 5 (not shown). In other embodiments, the contact on the float 45, Fig. 3 (not shown), comprises e disc 47 which makes contact with member 42 or with limbs 43, Fig. 6 (not shown). and terminal 39. In further embodiments, one contact comprises a contact pin 59, Fig. 4 (not shown), and 61, Fig. 5 (not shown), which engages a contact plate 52 on the float 51, Fig. 4, and the float itself 64, Fig. 5. Specification 918,870 is referred to.
