A switch assembly having a housing with a lower housing portion removably securable to an upper housing portion is provided. A switch subassembly including a printed circuit board (PCB) is removably secured within the lower housing portion. A mechanical switch assembly and a sensor are electrically connected to the PCB, and the PCB includes circuitry to place each of the mechanical switch assembly and the sensor into electrical communication with an external source. The switch assembly further includes a plunger engageable with the mechanical switch assembly. An attachment assembly for securing the upper housing portion to a mounting structure includes a mounting plate securable to the mounting structure, wherein the mounting plate includes at least one threaded opening. At least one opening is formed in the upper housing portion that is alignable with the threaded opening in the mounting plate that is sized and configured to receive a fastener.

1. A switch assembly, comprising: (a) a housing having a lower housing portion removably securable to an upper housing portion;(b) a switch subassembly receivable within the lower housing portion, the switch subassembly comprising a printed circuit board removably secured within the lower housing portion, the switch subassembly further comprising a mechanical switch assembly and a sensor electrically connected to the printed circuit board, wherein the printed circuit board includes circuitry to place each of the mechanical switch assembly and the sensor into electrical communication with an external source;(c) a plunger support removably receivable within a receptacle defined within the lower housing portion, the plunger support having a flange extending outwardly from the plunger support that is selectively engageable with a top surface of the printed circuit board to removably secure the printed circuit board within the lower housing portion such that the printed circuit board is positioned substantially parallel to the bottom surface of the lower housing portion; and(d) a plunger engageable with the mechanical switch assembly; and(e) an attachment assembly for securing the upper housing portion to a mounting structure, the attachment assembly comprising: (i) a mounting plate having at least one threaded opening, the mounting plate securable to the mounting structure; and(ii) at least one opening formed in the upper housing portion that is alignable with the threaded opening in the mounting plate and that is sized and configured to receive a fastener. 2. The switch assembly of claim 1, wherein the at least one opening formed in the upper housing is a slot configured to adjustably receive a fastener. 3. The switch assembly of claim 1, wherein the attachment assembly further comprises at least one spacer mateable with the housing and disposable between the upper housing portion and the mounting plate, the spacer having at least one opening that is alignable with the opening in the upper housing portion. 4. The switch assembly of claim 1, wherein the sensor is positioned on the printed circuit board such that it is receivable within an opening in the lower housing portion. 5. The switch assembly of claim 1, wherein the sensor is a thermal sensor. 6. The switch assembly of claim 1, further comprising an alignment assembly for maintaining the plunger in substantial linear alignment, the alignment assembly comprising a plunger guide extending from the plunger, the plunger guide slidably receivable within a plunger track formed within the bottom portion of the housing. 7. The switch assembly of claim 6, wherein the plunger support extends between the upper and lower housing portions to provide structural stability to the housing. 8. The switch assembly of claim 7, wherein a biasing member is engageable with a portion of the plunger to bias the plunger out of engagement with the mechanical switch assembly. 9. The switch assembly of claim 8, wherein the plunger support includes an annular protrusion sized and configured to receive a portion of the biasing member to position the biasing member on the plunger. 10. The switch assembly of claim 1, wherein the plunger is removably receivable within an opening defined in the plunger support to removably secure the plunger within the housing. 11. A switch assembly configured to trigger an alarm upon the activation of at least one switch assembly component, the switch assembly comprising: (a) a housing having a lower housing portion removably securable to an upper housing portion;(b) a switch subassembly receivable within the lower housing portion, the switch subassembly comprising: (i) a printed circuit board removably secured within the lower housing portion;(ii) a mechanical switch assembly electrically connected to the printed circuit board;(iii) a sensor electrically connected to the printed circuit board and positioned on the printed circuit board such that it is received within an opening in the bottom portion of the housing; and(iv) a quick disconnect assembly electrically connected to the printed circuit board and in electrical communication with the mechanical switch assembly and the sensor, the quick disconnect assembly configured to independently electrically connect the mechanical switch assembly and the sensor to an external source; and(v) a plunger support removably receivable within a receptacle defined within the lower housing portion, the plunger support having a flange extending outwardly from the plunger support that is selectively engageable with a top surface of the printed circuit board to removably secure the printed circuit board within the lower housing portion such that the printed circuit board is positioned substantially parallel to the bottom surface of the lower housing portion;(vi) a plunger engageable with the mechanical switch assembly, the plunger moveable between a first engaged position, wherein the mechanical switch assembly is in a first state, and a second disengaged position, wherein the mechanical switch assembly is in a second state; and(c) an attachment assembly for removably securing the upper housing portion to a mounting structure. 12. The switch assembly of claim 11, wherein the sensor is one of a thermal sensor and a motion sensor. 13. The switch assembly of claim 11, wherein the mechanical switch assembly is closed in the first state such that no electrical current is flowing between the mechanical switch assembly and the quick disconnect assembly. 14. The switch assembly of claim 11, wherein the mechanical switch assembly is open in the second state such that electrical current is flowing between the mechanical switch assembly and the quick disconnect assembly to electrically connect the mechanical switch assembly with the external source. 15. The switch assembly of claim 14, wherein the external source is an alarm that is triggered when the mechanical switch assembly is in the second state. 16. The switch assembly of claim 11, wherein the external source is an alarm that is triggered upon receiving a signal from one of the mechanical switch assembly and the sensor. 17. The switch assembly of claim 11, further comprising an alignment assembly for maintaining the plunger in substantial linear alignment, the alignment assembly comprising a plunger guide extending from the plunger, the plunger guide slidably receivable within a plunger track formed within the bottom portion of the housing. 18. The switch assembly of claim 17, wherein the plunger support extends between the upper and lower housing portions to provide structural stability to the housing. 19. The switch assembly of claim 11, wherein the attachment assembly comprises: (a) a mounting plate having at least one threaded opening, the mounting plate securable to the mounting structure; and(b) at least one opening formed in the upper housing portion that is alignable with the threaded opening in the mounting plate and that is sized and configured to receive a fastener. 20. The switch assembly of claim 19, wherein the attachment assembly further comprises at least one spacer mateable with the housing and disposable between the upper housing portion and the mounting plate, the spacer having at least one opening that is alignable with the opening in the upper housing portion.
