Description

【００１６】
＜実施の形態１＞
このスイッチ回路は、携帯用電気ドリル、インパクトドライバ、ジグソー、刈込み機等、ＤＣモータを使用した電動工具に利用可能であり、図１に示すように、ＡＣ電源５側に形成されたメイン接点としてのＡＣ用速度制御スイッチ１と、整流回路としてのブリッジダイオード７を介してＤＣ側に形成されたＤＣモータ１０と、このＤＣモータ１０に並列に接続された常時閉の接点８ａを有するブレーキ用接点８とを具備する。[0016]
Embodiment 1
This switch circuit can be used for portable electric drills, impact drivers, jigsaws, pliers and other electric tools using a DC motor, and as shown in FIG. 1, as a main contact formed on the AC power supply 5 side A DC speed control switch 1 for AC, a DC motor 10 formed on the DC side via a bridge diode 7 as a rectifier circuit, and a braking contact having a normally closed contact 8a connected in parallel to the DC motor 10 And eight.

【００１８】
ブリッジダイオード７は、交流電源を整流して全波もしくは半波の直流に変え、ＤＣモータ１０に供給するようになっている。[0018]
The bridge diode 7 rectifies the AC power supply to convert it into a full wave or half wave direct current, and supplies it to the DC motor 10.
