摘要	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.
