Switch arrangement device for connection to a wire

A device configured for installation on a wire, the device comprising:

• a housing;
• a wire passage provided in the housing;
• a blade positioned in the housing and configured to extend substantially through the wire passage, the blade dividing the wire passage into a first portion and a second portion;
• a first electrically conductive member positioned in the housing and configured to extend into the first portion of the wire passage, and a second electrically conductive member positioned in the housing and configured to extend into the second portion of the wire passage;
• a switch arrangement retained by the housing, the switch arrangement including an electrical pathway extending between the first electrically conductive member and the second electrically conductive member, the switch arrangement moveable between a closed position and an open position, wherein the electrical pathway is closed when the switch arrangement is in the closed position, and wherein the electrical pathway is open when the switch arrangement is in the open position;
• and
• a manual actuator configured to move the switch arrangement between the open position and the closed position.

A method of coupling an electronic module to an existing circuit, the method comprising:

• coupling a housing with a switching arrangement to a wire of the existing circuit, the switching arrangement including a manual actuator;
• severing the wire into a first end positioned within the housing and a second end positioned within the housing, the first end connected to a first terminal retained by the housing and the second end connected to a second terminal retained by the housing with an electrical pathway extending between the first terminal and the second terminal;
• connecting leads of the electronic module to the first terminal and the second terminal, the electronic module separate from the housing;
• and
• moving the manual actuator of the switching arrangement from a first position to a second position such that the electrical pathway is opened between the first terminal and the second terminal.
