Abstract
Abstract A burglar alarm and switch system comprising a switch having a unitary springlike contact element positioned within a recess of an integral block and resiliently held between two contact screws to provide a normally open or a normally closed switch. One end of the contact element is substantially fixed in position or anchored in the block contacting one of the contact screws while the extending portion is bent around in the recess to resiliently make and break contact with the other contact screw.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A switch comprising an integral block having an internal recess and an exit opening communicating with said recess, and a unitary springlike contacting element disposed in said recess, first and second contacting posts extending into said recess at spaced apart locations, one end of said contacting element being anchored in said block and resiliently contacting one of said contacting posts, said contaCting element having a base and a tongue extending from one side of said base and defining with said base a substantially V-shaped section, said tongue extending through said exit opening of said recess for engagement with an external member, said V-shaped section including a bent around portion to provide make and break contact with the other of said contacting posts in response to the external engagement of said tongue.
Claim 2
Dependent Claim
131 words
A switch comprising an integral block having an internal recess and an exit opening communicating with said recess, and a unitary springlike contacting element disposed in said recess, first and second contacting posts extending into said recess at spaced apart locations, one end of said contacting element being anchored in said block and resiliently contacting one of said contacting posts, said contaCting element having a base and a tongue extending from one side of said base and defining with said base a substantially V-shaped section, said tongue extending through said exit opening of said recess for engagement with an external member, said V-shaped section including a bent around portion to provide make and break contact with the other of said contacting posts in response to the external engagement of said tongue.
Claim 3
Dependent Claim
27 words
The switch of claim 1, including two spaced eyelets positioned in said block spaced from said recess to receive screws for fastening said switch to a frame.
Claim 4
Dependent Claim
