摘要： An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

摘要： Provided are a control switch mechanism, a trigger switch, and an electric tool, having vibration resistance and durability and capable of preventing malfunction. The control switch mechanism (20) includes an optical sensor (21) having a light emitting element (21a) and a light receiving element (21b), and a reflector (22) that increases or decreases an amount of light received by the light receiving element (21b). An increase and a decrease in output of an operation device are controlled along with an increase and decrease in amount of light received by the light receiving element (21b) due to relative movement between the optical sensor (21) and the reflector (22).

摘要： The present disclosure relates to a shift device for a control system for a vehicle. The shift device may include at least one optical fiber for conducting a light signal, where the light signal has an input characteristic when entering the shift device, and where the light signal has an output characteristic when exiting the shift device. The shift device may further include a control element, where the control element can be moved between a home position, a first actuation position, and a second actuation position by an actuation force. The control element may have an adjustment device for adjusting the characteristic of the light signal, where the adjustment device is configured to set the output characteristic of the light signal to a first value when the control element is in the home position.

摘要： An operator control device has a control panel with a user side facing a user and an inner side facing away from the user. The control panel has an operator control element region. A rotary knob is positioned on the user side of the control panel in the region of the operator control element region and can be rotated about a rotational axis. The rotary knob is detachably attached to the control panel and has an encoder block with a code section which is at a distance, changing along the circumferential direction, from a lower end side, facing the control panel, of the rotary knob. An optical sensor is arranged on the inner side of the control panel in the region of the operator control element region and is configured to sense a distance between the optical sensor and the code section of the encoder block by electromagnetic radiation.

摘要： A photoelectric switch, including: a main body, an upper cover, an infrared tube, an elastic shading mechanism, a bridge piece, a slidable switch member, a key, a sound mode trigger block, a silent mode trigger block, and an accommodating space. The slidable switch member is transversely slidable between the main body and the upper cover. The handle of the slidable switch member protrudes out of the main body. Both the sound mode trigger block and the silent mode trigger block are up-down movably disposed on the slidable switch member and move along with the slidable switch member. When the slidable switch member is slid to one side, the sound mode trigger block is disposed right beneath the key; and when the slidable switch member is slid to the other side, the silent mode trigger block is disposed right beneath the key.

摘要： A photoelectric switch, including: a base, an infrared tube, a keycap, a balance frame, a resetting mechanism, and a light-blocking member. The light-blocking member is configured to change the propagation direction of light emitted from the infrared tube to allow or block the light propagation in the infrared tube. The infrared tube is disposed on the base. The infrared tube includes a light-emitting end and a light-receiving end. The infrared tube, the balance frame, and the resetting mechanism are disposed beneath and covered by the keycap. In operation, upon being pressed by an external force, the balance frame leads the keycap to move downwards smoothly; the light-blocking member moves upwards or downwards along with the motion of the keycap and the balance frame or the resetting mechanism. The resetting mechanism is configured to reset the keycap or the balance frame.

摘要： A door switch includes a casing, a cam, the cam being caused to operate by manipulation of a manipulation key, and a detection unit for detecting an operating state of the cam. The casing houses at least a part of the cam and the detection unit. The cam is configured to be caused to operated by insert manipulation of inserting the manipulation key into the casing when the manipulation key has a shape adapted to a shape of the cam, and not to be caused to operate by the insert manipulation when the manipulation key does not have a shape adapted to the shape of the cam. The door switch can be adapted to Category 2 of ISO 13849-1.
