Abstract
Abstract An electrical switch having a two-part actuator, the first part of which has a guided path of movement that is substantially linear and the second part being pivotally attached to one end of the first part of the actuator and having an independent pivotal movement in one direction under spring tension during which it closes the switch contacts disposed in its path to momentarily pulse the switch irrespective of any directional movement of the first part of the actuator after the same has moved a predetermined distance.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
A pulse switch having a hollow housing containing the switch components including a switch contact member and a self-restoring actuator having a substantial linear reciprocal path of movement within the housing wherein the improvement comprises: a. an actuating means within said housing connected to and extending longitudinally of one end of the actuator and movable therewith and having an independent pivotal movement relative thereto into momentary contact with the switch contact member so as to complete a circuit therethrough; b. means connecting said actuating means pivotally to one end of the actuator; c. guide means within the housing in the path of movement of said actuating means and in contact therewith as it is initially moved by the actuator for resisting said actuating means independent pivotal movement until it and the actuator have moved a predetermined distance within the switch housing; and d. means connected to said actuating means for independently pivoting the same relative to its pivotal connection to the actuator and into momentary contact with the switch contact member after said actuating means has been moved by said actuator out of contact with said guide means.
Claim 2
Dependent Claim
188 words
A pulse switch having a hollow housing containing the switch components including a switch contact member and a self-restoring actuator having a substantial linear reciprocal path of movement within the housing wherein the improvement comprises: a. an actuating means within said housing connected to and extending longitudinally of one end of the actuator and movable therewith and having an independent pivotal movement relative thereto into momentary contact with the switch contact member so as to complete a circuit therethrough; b. means connecting said actuating means pivotally to one end of the actuator; c. guide means within the housing in the path of movement of said actuating means and in contact therewith as it is initially moved by the actuator for resisting said actuating means independent pivotal movement until it and the actuator have moved a predetermined distance within the switch housing; and d. means connected to said actuating means for independently pivoting the same relative to its pivotal connection to the actuator and into momentary contact with the switch contact member after said actuating means has been moved by said actuator out of contact with said guide means.
Claim 3
Dependent Claim
47 words
A pulse switch as defined by claim 1 wherein said means connected to said actuating means for independently pivoting the same comprises a spring connected between the actuator and said actuating means normally urging the pivotal movement of said actuating means about its connection to the actuator.
Claim 4
Dependent Claim
79 words
A pulse switch as defined by claim 1 wherein said guide means consists of a ramp member having a raised guide wall disposed in the path of movement of one end of said actuating means during its initial movement by the actuator and around and over which said actuating means moves during its independent pivotal movement relative to the actuator and into momentary contact with the switch contact member and return to its original position longitudinally of the actuator.
Claim 5
Dependent Claim
81 words
A pulse switch as defined by claim 2 wherein said guide means is an arcuated ramplike member having a raised guide wall disposed in the path of one end of said actuating means during its initial movement by the actuator and around and over which said actuating means is moved by said spring as it is independently pivoted relative to the actuator and into momentary contact with the switch contact member and returned to its original position longitudinally of the actuator.
Claim 6
Dependent Claim
43 words
A pulse switch as defined by claim 1 wherein said actuating means comprises an elongated lever providing on one face thereof adjacent one end a laterally extending guide lug for engaging said guide means during initial movement of said lever by said actuator.
Claim 7
Dependent Claim
48 words
A pulse switch as defined by claim 3 wherein said actuating means comprises an elongated lever providing on one face thereof adjacent one end a laterally extending guide lug that engages the raised guide wall of said ramp member during initial movement of said lever by said actuator.
