An electrical switch comprising of a non-conducting hollow housing and a number of spaced electrodes, each of which extends through the housing, and a contact member within the cavity which comprises of a core member having a layer of liquid gallium or gallium alloy adhered to and surrounding the core member. The contact member is moveable within the housing in response to movement of the housing, and able to electrically connect any two electrodes by positioning the gallium or gallium alloy layer in contact with the electrodes, and to electrically disconnect the electrodes by positioning the gallium or gallium alloy layer out of contact with the electrodes.
