Claims (22)

42511/3 What we claim is:
1. A temperature-actuatable snap-action device which assumes one configuration above a transition temperature and another configuration below said transition temperature, which device comprises two interacting spring members at least one of which exhibit a substantial change in force/deflection characteristics on passing through the transition temperature and at least one of which has a non-linear force/deflection curve having a maximum therein through which said member passes as the device snaps from one configuration to the other,
2. A device as claimed in claim 1 , wherein one spring member exhibits a negligible variation in force/deflection characteristics with temperature.
3. A device as claimed in any one of claims 1 or 2, wherein the spring member whose force/deflection curve passes through a maximum is the member which exhibits a substantial change in force/deflectio characteristics on passing through the transition temperature,
4. A device as claimed in claim 3, wherein the deflection of said spring member below the transition temperature lies on one .side of the maximum in its force/deflection curve at that temperatu and the deflection of said spring member above the transition temperature lies on the other side of the maximum in its force/ deflection curve at that higher temperature.
5. » A device as claimed in any one of claims 1 or 2, wherein the spring member whose force/deflection curve passes through a maximum does not exhibit a change in force/deflection characteristic on passing through the transition temperature. 42511/3
6. A device as claimed in claim 5» wherein the deflection of said spring member below the transition temperature lies on one side of the maximum in its force/deflection curve and the deflectio of said spring member above the transition temperature lies on the other side of said maximum.
7. A device as claimed in any one of claims 1 to 6, wherein the spring member which exhibits a substantial change in force/ deflection .characteristics on passing through the transition temper ture is made from a metal.
8. A device as claimed in claim 7» wherein the metal has a higher modulus above the transition temperature than below it.
9. · A device as claimed in claim 7 or claim 8, wherein the metal is an alloy of nickel and titanium.
10. A device as claimed in claim 9t wherein the alloy comprises about equal proportions of titanium and nickel.
11. A device as claimed in any one of claims 1 to 6, vrherein the spring member which exhibits a substantial change in force/ deflection characteristics on passing through a transition temperat is a polymer or a non-metallic elastomer.
12. A device as claimed in any one of claims 1 to 11, wherein th transition temperature lies below ambient temperature.
13. · A device as claimed in any one of claims 1 to 12, wherein on of said members is a longitudinally loaded leaf spring.
14. A device as claimed in any one of claims 1 to 12, wherein one of said members is a Belleville spring. 42511/3
15. '·" A device as claimed in claim 13 or claim 14» wherein the other spring member has two tines and the leaf spring or the Belleville spring is located between the tines,
16. A device as claimed in claim 15f wherein the other spring member is a curved end cantilever spring and the leaf spring or the Belleville spring is located across the curved end thereof.
17. A device as claimed in any one of claims 1 to 16, which is, or is part of, a connector.
18. A device as claimed in claim 17, wherein at least one of said spring members includes a projection or similar portion adapted to make good electrical contact.
19. · A device as claimed in claim 1, substantially as described herein with reference to, and as illustrated in, Figure 1, Figure 2 or Figure 3 of the accompanying drawings.
20. A method of making a connection which comprises bringing an object or objects into contact with a device as claimed in claim 17, and then effecting the temperature change necessary to actuate the device.
21. A method as claimed in claim 21 , wherein the temperature change is a rise in temperature.
22. A' method as claimed in claim 20 or claim 21, wherein a connection is made to a printed circuit board.
