In some examples, a switch assembly may switch from one electrical contact to another electrical contact by moving a conductive spring or member from a first conductive contact on a printed circuit board (PCB) to a second conductive contact on the PCB. For instance, in one embodiment, a conductive member moves within a slot in the PCB. In another embodiment, a compression force applied to a conductive spring is reduced while the conductive spring moves from a first conductive contact to a second conductive contact. ## Claims ### Claim 1 A switch assembly comprising: a substrate having at least one first conductive contact;
