Abstract
Abstract In order to provide better visual indication of the position of an actuating means such as a push button switch there is provided a means for translating the longitudinal movement thereof into the movement perpendicular thereto of an indicating member. Said member, or a device coupled thereto can be more readily observed than the actuating means.

Claim 1
Independent Claim
324 words
Indicator means for indicating the operating condition of a push-button switch, comprising a. a stationary member (34); b. switch means including a push-button member (30) that is axially displaceable between depressed and released positions adjacent and remote from said stationary member, respectively, thereby to switch said switch means from one operating condition to the other, the end of said push-button member adjacent said stationAry member containing a longitudinal bore that terminates in a chamber adjacent the end of said pushbutton member that is remote from said stationary member; c. means for indicating the position of said push-button member relative to said stationary member and, consequently, the condition of said switch means, said indicating means comprising 1. an indicator member (38) mounted in said chamber for radial sliding movement between first and second indicating positions relative to the axis of said push-button member, the remote end portion of said push-button member containing an opening affording a visible indication of the position of said indicator member; 2. a lever member (31) arranged longitudinally within the bore of, and pivotally connected intermediate its ends with, said push-button member, said lever member being pivotable about an axis normal to the plane that contains both the axis of said push-button member and the axis of sliding movement of said indicator member, said lever member being adapted at one end to slidably operate said indicator member and having at its other end a pointed extremity (33) that projects outwardly from said push-button member; and 3. spring means (37) biasing said indicator member toward one of its indicating positions when said push-button member is in the released position, said stationary member containing a recess (35) having a conically convergent orifice so arranged relative to the pointed extremity of said lever member that when said push-button member is displaced toward the depressed position, the lever member is pivoted by the orifice walls to displace the indicator member toward the other indicating position.

Claim 3
Dependent Claim
83 words
a lever member (31) arranged longitudinally within the bore of, and pivotally connected intermediate its ends with, said push-button member, said lever member being pivotable about an axis normal to the plane that contains both the axis of said push-button member and the axis of sliding movement of said indicator member, said lever member being adapted at one end to slidably operate said indicator member and having at its other end a pointed extremity (33) that projects outwardly from said push-button member; and
Claim 4
Dependent Claim
83 words
a lever member (31) arranged longitudinally within the bore of, and pivotally connected intermediate its ends with, said push-button member, said lever member being pivotable about an axis normal to the plane that contains both the axis of said push-button member and the axis of sliding movement of said indicator member, said lever member being adapted at one end to slidably operate said indicator member and having at its other end a pointed extremity (33) that projects outwardly from said push-button member; and
Claim 5
Dependent Claim
75 words
spring means (37) biasing said indicator member toward one of its indicating positions when said push-button member is in the released position, said stationary member containing a recess (35) having a conically convergent orifice so arranged relative to the pointed extremity of said lever member that when said push-button member is displaced toward the depressed position, the lever member is pivoted by the orifice walls to displace the indicator member toward the other indicating position.
Claim 6
Dependent Claim
75 words
spring means (37) biasing said indicator member toward one of its indicating positions when said push-button member is in the released position, said stationary member containing a recess (35) having a conically convergent orifice so arranged relative to the pointed extremity of said lever member that when said push-button member is displaced toward the depressed position, the lever member is pivoted by the orifice walls to displace the indicator member toward the other indicating position.
