Box cover for limit switch

Socket for indicating lamp

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.

Switch

Push switch

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.

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.

Provided is a switch that can reliably bring contacts into contact with each other with a small load, and can be prevented from malfunctioning. 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 an opposite direction to a returning direction when the plunger is in the operation position, and biases the plunger in a direction different from the opposite direction to the returning direction when the plunger is in the reference position.

Main body of push switch

Provided is an electronic device that is highly resistant to a water-soluble grinding oil and a method for manufacturing the same. An electronic device includes a main body and a cable including a lead wire, an insulating portion, and an outer coat, a first sealing portion that covers the insulating portion, and a second sealing portion that seals the first sealing portion, the insulating portion is made of a material that is more resistant to a water-soluble grinding oil than the outer coat is, and the first sealing portion is made of a material that has higher adherence to the insulating portion than that of the second sealing portion does.

Electronic device and method for manufacturing the same

A switch has a rotary shaft that rotates in response to an external force, a cam provided on the rotary shaft and including a cam action section, wherein the cam rotates in response to the rotation of the rotary shaft, a displacement member including a cam support section that contacts the cam action section, wherein the displacement member is displaced in response to the cam support section being pressed by the cam action section rotating, and a switch module that performs an on-off action in response to the displacement of the displacement member. The cam action section is made of a metal. The cam support section is made of a resin softer than the cam action section.
