Leading ends 23 of cores of a cable 7 introduced into the switch case 3 are inserted in insertion holes 49a, 49b formed in the terminal block 9. Screws 53a, 53b mounted to the terminal block 9 are tightened to press the leading ends 23 of the cores against conductive connection portions, on one side, in the insertion holes 49a, 49b, thereby to establish electrical connection. <IMAGE>
