Abstract

553,489. Actuation of switches. BLISS, CO., E. W. Sept. 30, 1942, No. 13727. Convention date, Oct. 28, 1941. [Class 38 (v)] A retractive switch 12 is operated by increase or decrease of pressure in an air line by movement of a diaphragm 16 forming one wall of a rigid air drum 15. The adjustable mounting of the switch 12 is fitted with springs 27 holding lugs on the switch rigid mounting-piece against the heads of bolts 26, all within a housing 30.
