Abstract
A bypass switch provides a bypass path between a first terminal and a second terminal. The bypass switch includes: a first contact device; a second contact device; and a plunger being moveable from an initial state, via a first state, to a second state, wherein in the initial state the first terminal and second terminal are conductively separated; in the first state a movement of the plunger causes the first contact device to close a first conductive connection between the first terminal and the second terminal; and in the second state the plunger mechanically forces the second contact device to close a second conductive connection between the first terminal and the second terminal.
Claims20
A bypass switch for providing a bypass path between a first terminal and a second terminal, the bypass switch comprising:
- a first contact device;
- a second contact device;
- and
- a plunger being moveable from an initial state, via a first state, to a second state, wherein in the initial state the first terminal and second terminal are conductively separated;
- in the first state a movement of the plunger causes the first contact device to close a first conductive connection between the first terminal and the second terminal;
- and in the second state the plunger mechanically forces the second contact device to close a second conductive connection between the first terminal and the second terminal, AND
- wherein the plunger comprises a front section and a back section, wherein the front section is detachably connected to the back section, and wherein, in the first state, it is the back section which causes the first contact device to close the first conductive connection.
A method for providing a conductive path between a first terminal and a second terminal, the method being performed in a bypass switch comprising a first contact device;
- a second contact device;
- and a plunger, wherein the method comprises the steps of:
- moving the plunger from an initial state to a first state wherein in the initial state the first terminal and second terminal are conductively separated, and in the first state the plunger causes the first contact device to close a first conductive connection between the first terminal and the second terminal;
- and
- moving the plunger from the first state to a second state, wherein in the second state the plunger mechanically forces the second contact device to close a second conductive connection between the first terminal and the second terminal,
- wherein the plunger comprises a front section and a back section, wherein the front section is detachably connected to the back section, and wherein, in the first state, it is the back section which causes the first contact device to close the first conductive connection.
