Abstract

1,192,186. Liquid-break switches. PLASTICS Inc. 30 Aug., 1967, No. 39663/67. Heading H1N. A switch has a sealed housing A including a body 19 of transparent material and end closure plates 20, 23 sealed to the body. At least one pair of spring contact blades 34 is mounted on the plate 23 so as to be insulated from one another and biased to move into contact with one another. A switch member 60 is slidably mounted on the other plate for movement into the position shown in which it separates the blades to interrupt the circuit between them. The housing is filled with transparent oil so that the blades can be seen through the body 19 and the oil. The member 60 may be wholly of insulating material, but in an arrangement having two pairs of contact blades 34, the member 60 may have conducting strips 39 so that when the blades are separated, each blade of one pair is connected to the respective blade of the other pair. In this switch arrangement the member 60 is carried by two rods (one shown) which extend through the plate 20 to a transverse bar 67. This bar may serve as the operating member or be moved by a pivoted lever 69 which may be latched in its upper position by a pivoted latch arm 70, the end of which may engage in an indentation 72 in the plate 20. The body A is cylindrical and it is supported in a pressed-out part 16 of a mounting plate 11.
