A switch according to one or more embodiments may include a movable unit movable in response to an operation. A drive unit is drivable in response to movement of the movable unit. The switch may include an operation-linked unit movable in response to the movement of the movable unit and an operation follower unit spaced from the operation-linked unit to move in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit. At least one of the operation-linked unit or the operation follower unit is magnetic. The drive unit is drivable in response to movement of the operation follower unit. The operation follower unit accommodated in a chamber is spaced from the operation-linked unit.

Switch

A trigger switch according to one or more embodiments may include a first conductive plate (movable electrode) movable in response to movement of a trigger receiving a depressing operation, and a second fixed electrode (fixed electrode) located adjacent to a movable range of the first conductive plate with a space in between. The second fixed electrode forms a capacitor together with the first conductive plate. The capacitor formed by the first conductive plate and the second fixed electrode has a capacitance that changes as the first conductive plate moves.

Trigger switch

In response to a measured value of temperature of a stator by a thermometer exceeding a first temperature threshold, an overheat signal may be output to a rotor of a rotary connector via a communication device. In response to the measured value of the temperature exceeding a second temperature threshold higher than the first temperature threshold, power supply to a transmission coil that transmits power to a receiving coil of the rotor in a non-contact manner is stopped. In response to the overheat signal being received or a measured value of temperature of the rotor by a thermometer exceeding a third temperature threshold, a limit signal for limiting current flowing through a load circuit is output. In response to the measured value of the temperature by the thermometer exceeding a fourth temperature threshold higher than the third temperature threshold, output of power received from the stator is stopped.

Rotary connector

A metal detectorincludes a detection signal acquisition unit, a threshold value setting and updating unit, and a determination unit. The detection signal acquisition unitacquires a detection signal that changes according to the detection strength for a rebar Wcontained in concrete W, on the surface of the concrete W. The threshold value setting and updating unitsets a threshold value in order to determine the presence or absence of the rebar Won the basis of the maximum value and/or the minimum value included in the acquisition results for the detection signal acquired by the detection signal acquisition unit. The determination unitdetermines the presence or absence of the rebar Wby using the threshold value set in the threshold value setting and updating unit
