Abstract

A high security switch for use with an alarm includes a switch assembly for mounting to a fixed structural member. The switch assembly includes a pressure sensitive switch; a magnetic attractive movable body; a cavity having a first end and second end, the cavity confining, directing, limiting and defining the travel of the movable body; and a biasing element near the first end of the cavity to position the moveable body adjacent the first end of the cavity. The switch also includes an actuating element coupled to a movable structural member. In response to moving the actuating element away from the switch assembly the moveable body is magnetically acted upon by the biasing and moved from the second end to the first end of the cavity. The electrical state of the pressure sensitive switch is changed and an alarm activated.

Claims

1. A high security switch for use with an alarm comprising:

a switch assembly for mounting to a fixed structural member, the switch assembly comprising;

a pressure sensitive switch comprising a push button, wherein the push button is moveable between a first and second position;

a magnetic attractive movable body;

a cavity having a first end and second end, the cavity confining, directing, limiting and defining the travel of the magnetic attractive movable body; and

a biasing element near the first end of the cavity to position the moveable body adjacent the first end of the cavity; and

an actuating element coupled to a movable structural member, wherein;

in response to moving the actuating element away from the switch assembly the magnetic attractive moveable body is magnetically acted upon by the biasing element to move the magnetic attractive moveable body from the second end to the first end of the cavity allowing the push button to move to the first position and activating an alarm; and

in response to moving the actuating element toward the switch assembly the magnetic attractive moveable body is magnetically acted upon by the actuating element to move the moveable body to the second end of the cavity wherein the magnetic attractive moveable body engages the push button and moves it to the second position.

2. The switch of claim 1, wherein the cavity is angled to create a sloped cavity wherein the first end is higher than the second end and the moveable body can travel substantially linearly between the first end and the second end.

3. The switch of claim 2, wherein the cavity is sloped upwardly and outwardly from the fixed structural member.

4. The switch of claim 1, wherein the actuating element comprises a stronger magnetic influence on the moveable body than the biasing element.

5. The switch of claim 1, wherein the magnetic attractive moveable body is moved from the second end to the first end of the cavity in response to placing an external magnet adjacent a switch assembly.

6. A method of using a high security switch with an alarm system comprising:

mounting a switch assembly to a fixed structural member;

mounting an actuating member to a moveable structural member;

positioning the actuating member adjacent the switch assembly;

maintaining a pressure sensitive switch of the switch assembly in a second electrical state in response to positioning the actuating member adjacent the switch assembly, wherein the pressure sensitive switch comprises a push button, wherein the push button is moveable between a first and a second position;

moving the actuating member away from the switch assembly;

changing the pressure sensitive switch from the second electrical state to a first electrical state in response to moving the actuating member away from the switch assembly; and

activating an alarm in response to the pressure sensitive switch being moved to the first electrical state.

7. The method of claim 6, further comprising placing an external magnet adjacent the switch assembly.

8. The method of claim 7, further comprising changing the pressure sensitive switch from the second electrical state to a first electrical state in response to placing the external magnet adjacent the switch assembly.
