Abstract
794,055. Switches held set and freed mechanically; momentary-contact switches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 7, 1955 [Sept. 10, 1954], No. 25638/55. Class 38 (5). In a push-button switch, the button 42, after being depressed against the action of a spring 33, is latched against return movement by a slight sideways tilt which causes a slot 45 to engage the side of an aperture 32 in a plate 23, release being effected by sideways movement of the button. The button is linked to the contacts (not shown) by a pin 39, a lever 40 and link 41. The slot 45 is so shaped that during the locking and unlocking tilting movements, the button moves in a direction opposite to the sliding movement immediately preceding or following the tilting, so as to momentarily change-over contacts 49, 50, 51. Two or more switches may be mounted side by side.
