Claims: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A temperature sensitive and gravity sensitive switch including a pair of flexible conductive arms arranged for contact adjacent one end thereof, insulation means mounting and separating the opposite ends of said arms, a temperature responsive actuating arm and insulating means mounting and separating one end thereof from said conductive arms, means on said actuating arm positioned for contact with one of said conductive arms to effect opening and closing of said conductive arms,

a bracket in electrical contact with a conductive arm and mounted thereto by said insulation means, and a conductive liquid tipswitch mounted in said bracket and connected in series with said conductive arm through said bracket.

2. The structure of claim 1 further characterized in that said bracket includes an opening, locating means in said opening for positioning said conductive liquid tipswitch within said opening.

3. The structure of claim 2 further characterized in that said conductive liquid tipswitch has a generally cylindrical outer housing, at least one axially extending groove in the outer surface of said housing, said locating means including a projection integral with said bracket and extending into said opening.

4. The structure of claim 3 further characterized by and including a pair of circumferentially-extending spaced projections extending into said opening for locating said conductive liquid tipswitch therewithin.

5. The structure of claim 1 further characterized in that said insulation means include a plurality of separate discs, there being one disc between said flexible conductive arms and a second disc between one of said arms and said temperature responsive actuating arm.

6. The structure of claim 5 further characterized in that said bracket has a portion thereof lying flat upon a portion of a conductive arm.

7. The structure of claim 6 further characterized in that said insulation discs, bracket, temperature responsive actuating arm and flexible conductive arms are all secured together in a single stack.

8. The structure of claim 7 further characterized by and including strengthening means formed in said bracket between said tipswitch and the portion of the bracket lying flat against a conductive arm.

9. The structure of claim 1 further characterized by and including a terminal connected to one of said conductive arms and a second terminal connected to said conductive liquid tipswitch, said bracket being in electrical contact with the other of said conductive arms.
