The electrical switch includes a first and a second fixed contact, and a rotatable knife contact including at least one pair of blades being flexibly connected to each other and rotating around a rotational axis. A third fixed contact is positioned on an opposite side of the rotational axis in relation to the adjacent first and second fixed contact and a middle portion of the rotatable knife contact is electrically connected to the third fixed contact. The rotatable knife contact connects in a first switching position the first fixed contact and in a second switching position the second fixed contact to the third fixed contact.

A computer device including an integrated input device is provided. The integrated input device includes a positive disconnect system including a display of an open connection to the integrated input device when the integrated input device is deactivated. The open connection comprises a visible metal trace on a line coupling the integrated input device to the computer device.

A gyral-linear actuator for an encoder comprises an actuator housing having a first end, a second end opposite the first end, and a hollow. A control member extends from the first end of the actuator housing. A spring is positioned within the hollow of the actuator housing. Moreover, a coupler has an encoder connector and an extension that couples the control member to the encoder connector. Under this configuration, when the encoder connector is coupled to a rotary shaft of the encoder, rotation of the control member causes corresponding rotation of the encoder connector so as to turn the rotary shaft of the encoder, and depression of the control member causes corresponding depression of the rotary shaft of the encoder operating a switch function of the rotary encoder.

An improved mechanical interlock is disclosed. The mechanical interlock includes one or more features to facilitate a more robust design, easier assembly, and/or enhanced capabilities. For example, the mechanical interlock may include an interlock latch operatively associated with an external handle assembly and an internal connector. The interlock latch being directly coupled to a shaft coupled to the handle assembly, thus providing an improved and more robust latching mechanism. The mechanical interlock may also include one or more keys (e.g., a Poke-Yoke feature) to facilitate easier assembly and/or to prevent human errors caused by improper assembly. The mechanical interlock may also include an integrated magnetic switch and monitoring system to ensure that accurate location of the handle assembly is known.

A rotation operation input device that achieve downsizing and excellent durability while offering clear and good operation feeling. The rotation operation input device comprises detected portions which is provided concentrically with a rotation operation member about a rotation axis and rotates along with rotation of the rotation operation member, and a detection unit which detects the detected portions and a phase of the rotation operation member. The detected portions are provided at a predetermined interval along an outer edge of the rotation operation member, this outer edge is provided with a recess/protrusion part, the recess/protrusion part has recess parts each positioned between the detected portions and protrusion parts each positioned on each straight line connecting each detected portion and the rotation axis, and an urging member that urges the recess/protrusion part is provided on a side opposite to the detected portions across the recess/protrusion part.

A multi-gear brightness adjustment circuit board, and a multi-gear battery holder structure, which through adding the automatic control gear AUTO conductive contact piece and a light spot dot-circle pattern composite conductive contact piece on the circuit board, the gear can be automatically adjusted when the solar cell is used for power supply. Ensuring that the output light power meets the needs of ambient light, rationally use electric energy, which is conducive to energy saving; at the same time, the mode switching of the shooting target is integrated, which reduces the parts of the sight and makes the sight more compact.

A knob assembly includes a lower housing, a pushing member, an upper housing, and a screw member. The lower housing includes a tank and hook structures. A through via is formed at the center of the lower housing. The upper housing is rotatably stacked on the lower housing. A lower surface of the upper housing includes an annular hook groove. The pushing member is disposed between the upper and the lower housing, and includes a body and pushing structures. A screw hole is formed at the center of the body. When the screw member is screwed into the screw hole through the through via, the pushing member moves toward and locks the lower housing, and the pushing structures push the hook structures to cause the hook structures to expand outward and be hooked to the annular hook groove, so that the upper housing is limited by the lower housing.

A disconnector that includes at least two modular contact boxes, each one having a box-like body coupled to a contiguous box-like body of a contiguous modular contact box. Each box-like body defines a seat that accommodates a moving contact and two peripheral seats, each of which accommodates a corresponding fixed contact that can be accessed from outside the modular contact box. The at least two box-like bodies include at least one first box-like body, in which at least the outward-facing surface has a first finish, and at least one second box-like body, in which at least the outward-facing surface has a second finish, the contacts of the first box-like body or bodies having one polarity and the fixed contacts of the second box-like body or bodies having an opposite polarity.
