<p>PROBLEM TO BE SOLVED: To provide a switch having a light dimming circuit which is extremely practical and is also excellent in productivity by controlling a phase of a gate trigger pulse of a TRIAC whose light dimming circuit is connected between a load and a power source by an integrated circuit. SOLUTION: In this switch having a light dimming circuit, a switch main body 5 enclosing a light dimming circuit to be softly turned on and softly turned off by controlling a phase of a gate trigger pulse of a TRIAC connected between a load and a power source by an integrated circuit, is housed and installed in an indoor wiring embedded box of a standard type. In this case, it can be made further convenient by adding a control circuit actuated by another switch arranged in a separate place.</p> |
