摘要:
A light projecting circuit of a photoelectric switch includes a light projecting element (2), a driver circuit (1, 3) for driving the light projecting element by use of pulses, and a change-over switch (4) for increasing or for decreasing an amount of light emitted from the light projecting element. With this provision, in an operation to adjust optical axes, the change-over switch can be used to increase the amount of the emitted light. Consequently, the position of the projected light beam can be easily confirmed.
