Sensor switch includes a compromisable mechanical restrainer and a biased member. Before compromise, the restrainer can hold the biased member in a first position. When contacted with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased member can assume a second position different from the first position. Monitoring a sample for a target chemical and/or composition can be carried out with the sensor switch.

1.

1. A sensor switch for chemical/composition detection, which comprises a compromisable mechanical restrainer, a biased first member, and a second member, wherein: before compromise, the restrainer can hold the biased first member in a first position, and, upon contact with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased first member can assume a second position different from the first position to make or break contact with the second member; andthe sensor switch operates only by an all-or-none, “open/close” configuration feature such that when the first position provides for the “open” configuration, direct physical contact between the biased first member and the second member is not present, which could be closed by making contact of the biased first member with the second member; and when the first position provides for “close” configuration, direct physic contact between the biased first member and the second member is present, which could be opened by breaking contact of the biased first member with the second member. 2. The sensor switch of claim 1, wherein the restrainer includes a foamed plastic. 3. The sensor switch of claim 1, wherein the restrainer includes a soft reticular plastic core having a coat of a rigid polymer sensitive to the target chemical and/or composition. 4. The sensor switch of claim 2, wherein a microswitch is employed. 5. The sensor switch of claim 3, wherein a microswitch is employed. 6. The sensor switch of claim 1, which further comprises a housing about the sensor switch, which has a screen for access of the target chemical and/or composition. 7. The sensor switch of claim 6, wherein the housing is weighted about a bottom thereof, and the screen is made to be or include copper. 8. A method for monitoring a sample for a target chemical and/or composition, which comprises the following steps, which are not necessarily conducted in series: providing a sensor switch for chemical/composition detection, which comprises a compromisable mechanical restrainer, a biased first member, and a second member, wherein: before compromise, the restrainer can hold the biased first member in a first position, and, upon contact with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased first member can assume a second position different from the first position to make or break contact with the second member, wherein the sensor switch has the restrainer in the first position before compromise; andthe sensor switch operates only by an all-or-none, “open/close” configuration feature such that when the first position provides for the “open” configuration, direct physical contact between the biased first member and the second member is not present, which could be closed by making contact of the biased first member with the second member; and when the first position provides for the “close” configuration, direct physical contact between the biased first member and the second member is present, which could be opened by breaking contact of the biased first member with the second member; andintroducing the sensor switch to the sample such that, when contacted with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased member assumes the second position different from the first position for detection of the target chemical and/or composition. 9. The method of claim 8, which is conducted in water. 10. The method of claim 9, wherein the sensor switch floats in the water. 11. A sensor switch for chemical/composition detection, which comprises a compromisable mechanical restrainer, a biased first member, and a second member, wherein: before compromise, the restrainer can hold the biased first member in a first position, and, upon contact with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased first member can assume a second position different from the first position to make or break contact with the second member;the sensor switch operates only by an all-or-none, “open/close” configuration feature such that when the first position provides for the “open” configuration, direct physical contact between the biased first member and the second member is not present, which could be closed by making contact of the biased first member with the second member; and when the first position provides for the “close” configuration, direct physical contact between the biased first member and the second member is present, which could be opened by breaking contact of the biased first member with the second member; andat least one of electricity and light is employed in conjunction with the “open/close” configuration feature. 12. The sensor switch of claim 11, wherein the electricity is employed in conjunction with the “open/close” feature such that when the “open” configuration is present an electrical circuit is not made between the biased first member and the second member, and when the “close” configuration is present an electrical circuit is made between the biased first member and the second member; and the first position of the biased first member does not make contact with the second member to provide the “open” configuration until the second position different from the first position is assumed, upon which the first biased member makes contact with the second member to provide the “close” configuration. 13. The sensor switch of claim 11, wherein the electricity is employed in conjunction with the “open/close” feature such that when the “open” configuration is present an electrical circuit is not made between the biased first member and the second member, and when the “close” configuration is present an electrical circuit is made between the biased first member and the second member; and the first position of the biased first member makes contact with the second member to provide the “close” configuration until the second position different from the first position is assumed, upon which the first biased member breaks contact with the second member to provide the “open” configuration. 14. The sensor switch of claim 11, wherein the second member comprises an optical fiber, and the light in the optical fiber is employed in conjunction with the “open/close” feature such that when the “open” configuration is present light passes from one position to another in the optical fiber, and when the “close” configuration is present the biased first member assumes the second position different from the first position to make contact with, and disrupt the optical fiber, and the light passing therein. 15. The sensor switch of claim 11, wherein bias in the biased first member is provided by at least one of a spring, a magnet, and gravity. 16. The sensor switch of claim 11, wherein the restrainer includes a foamed plastic. 17. The sensor switch of claim 11, wherein the restrainer includes a soft reticular plastic core having a coat of a rigid polymer sensitive to the target chemical and/or composition. 18. The sensor switch of claim 12, wherein the restrainer includes a soft reticular plastic core having a coat of a rigid polymer sensitive to the target chemical and/or composition. 19. The sensor switch of claim 13, wherein the restrainer includes a soft reticular plastic core having a coat of a rigid polymer sensitive to the target chemical and/or composition. 20. The sensor switch of claim 11, wherein a microswitch is employed.
