摘要： An arc quenching device, which is highly reliable, small-sized, and inexpensive, includes: a semiconductor switch connected in parallel to a first switch which is mechanical; a constant voltage circuit configured to use a voltage which is generated between both contact points of the first switch to output a voltage which causes the semiconductor switch to turn on; and a second timer circuit configured to cause the semiconductor switch to turn off after a predetermined time has elapsed since the semiconductor switch turned on.

摘要： Provided is a switch that can be downsized. A switch is provided with a plunger, and an upper torsion spring configured to bias the plunger in a returning direction. The torsion spring has a first arm that extends to the plunger and abuts against the plunger. The plunger has a hole at a position into which the first arm is inserted. The hole is a through hole extending in a direction that is perpendicular to a direction in which the plunger moves, and is the same as a direction in which the first arm extends when viewed in the direction in which the plunger moves.

摘要： An arc quenching device, which prevents a load device from displaying an unnecessary behavior during starting of a power supply, includes: a semiconductor switch connected in parallel to a first switch which is mechanical; a power supply circuit configured to use a voltage which is generated between both contact points of the first switch to output a voltage which causes the semiconductor switch to turn on; and a second switch configured to cause its open state to prevent the semiconductor switch from turning on.

摘要： Provided is a switch with excellent operability. A switch is provided with a plunger, a lower torsion spring in which a biasing direction changes according to the movement of the plunger. The lower torsion spring biases the plunger in a returning direction when the plunger is in a reference position, and biases the plunger in a direction different from the returning direction when the plunger is in an operation position.

摘要： Provided is a switch that can be downsized. A switch is provided with a plunger, two upper torsion springs that bias the plunger in a returning direction, housing-side contacts, and plunger-side contacts. One of the upper torsion springs is arranged on one side of a plane that includes an axis passing through a central portion of the plunger, and that is perpendicular to perpendicular lines M connecting the plunger-side contacts and the axis, and the other one of the upper torsion springs is arranged on the other side of the plane.
