Abstract

PURPOSE:To imcrease the range of utilization of a two-wire switch by connecting an adapter in parallel to a high-impedance load. CONSTITUTION:A two-wire photoelectric switch body 1 and a load 3 are connected to a power source 7. The load 3 is connected in parallel to an adapter 5. The photoeletric switch 1 is composed of an SCR14, an oscillating circuit 16, a projecting element 17, a photodetecting element 18, a photodetecting circuit 19, and a switching curcuit 20. Then, even when the impedance of the load 3 is infinite, a current can be supplied to the main body 1 through the adapter 5, so the load 3 is switched by the main body 1 securely.
