An operation apparatus includes: an operation plate having an operation surface performed by a pressing operation with an operation body; a vibrator including a movable yoke and a fixed yoke for generating a magnetic circuit for guiding a magnetic flux, and an exciting coil for generating the magnetic flux, and the vibrator vibrating the operation plate through a magnetic force generated by an electrical conduction on the exciting coil; a detector detecting a pressing amount by the pressing operation; a press determinator determining based on the pressing amount detected by the detector whether the pressing operation is performed; and a vibration controller for an electrical conduction on the exciting coil when the press determinator determines that the pressing operation is performed. The detector detects the pressing amount by detecting a change in an electrostatic capacitance generated between the movable yoke and the fixed yoke.

A key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.

A switch includes a pushbutton comprising an actuating portion, a first fixed contact element and a first movable contact element facing the first fixed contact element for establishing a first switching way. The first movable contact element may include a movable portion of a first elastically deformable conductive blade. The actuating portion may include a first cam which cooperates with a cam follower portion of the first blade to deform or relax the first blade for longitudinally moving the first movable contact element to come into contact, or out of contact, with the portion of the first fixed contact element, depending on the vertical position of the actuation member. A second fixed contact element and second movable contact may be similarly constructed to provide a second switching way.

Implementations of a multi-pole dome switch configured to simultaneously, or nearly simultaneously, close or open two separate circuits are provided. In some implementations, a multi-pole dome switch may comprise a tactile metal dome and a conductive insert that are separated by an insulator. In some implementations, when the dome is depressed, the dome and the conductive insert are configured to simultaneously, or nearly simultaneously, make conductive contact with two traces of a first circuit and two traces of a second circuit, respectively, positioned thereunder on a PCB. In this way, the multi-pole dome switch is able to simultaneously, or nearly simultaneously, close two separate circuits. Succinctly put, in some implementations, the multi-pole dome switch may be configured to act as a double-pole, double-throw switch.

A trigger switch used in electric devices such as various types of electric tools may be provided that drives a drive unit, such as a drive motor of the electric device, by pushing a trigger. A trigger switch includes a mode switching lever that switches between a constant speed mode in which the drive unit is driven at constant speed and a shift mode in which the drive unit is driven by an output corresponding to a pushing amount of a trigger. Further, the mode switching lever includes a regulating portion that regulates the pushing amount of the trigger according to the switched mode.
