PURPOSE:To reduce a space necessary for installing a switch by placing an indicator lamp between a common terminal strip and the other terminal strip among a plurality of terminal strips to be connected to the terminal of the switch. CONSTITUTION:Terminal strips 9 comprising an L-shaped common terminal strip 9a with a penetrating hole 8 and a normally opened terminal strip 9b are fixed to the ends positioned. Along the longitudinal direction of the printed circuit board of a substrate 7 having insulating property and made in a rectangular form or the like opposing to each other. In addition, a series circuit comprising a resistance 11 and an indicator lamp 12 is connected between both terminal strips 9a and 9b through a printed circuit conductor 10. The indicator lamp consists, of for instance a light emitting diode or an incandescent lamp. To a lead wire 15 forming a power circuit or a control circuit is connected a compressively attached terminal 17 with a penetrating hole 16, the terminal 17 is fixed onto the switch 1 together with each terminal strip 9 through each terminal screw 5, each terminal screw 5 is passed through the penetrating hole 16 of the compressively attached terminal 17 and the penetrating hole 8 of each terminal strip 9 and screwed into each threaded hole 4, and thus an indicator lamp unit 13 is fixed onto the switch 1 and further the lead wire 15 is connected to a common terminal 2a and normally opened terminal 2b. |
