Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A remote controlled sound muting device for operating an audio jack switch comprising: a housing; a hollow shank extending from and fixed to said housing for extending into the audio jack; engaging means on said shank for snugly gripping the inside of the audio jack and preventing rotation of the shank; a cam member rotatably mounted in said shank and extenting beyond the end of said shank into said audio jack to actuate the audio circuit contacts in the audio jack; a shaft connected to said cam member; means for driving said shaft in steps to alternately open and close said audio circuit contacts; and remote actuator means for operating said means for driving said shaft.
Claim 2
Dependent Claim
