A switch device includes an operating knob on which a tilting operation is performed, a detected portion that tilts with the tilting operation of the operating knob, a detection portion that detects movement of the detected portion, and a substrate on which the detection portion is arranged. The detection portion is aligned in an in-plane direction of the substrate and performs a switching operation upon detection of movement of the detected portion in the in-plane direction.

An electronic device includes a rotation operation unit including a rotation operation member, and a finger placing portion configured so that a finger is placed on it when the electronic device is gripped. The rotation operation unit and the finger placing portion are located in close proximity to each other on a surface on a user side of the electronic device. The rotation operation unit is tilted with respect to the electronic device toward the finger placing portion.

According to the present invention, an optical latch circuit includes a voltage detector configured to compare a first power generation voltage input from a first input terminal with a preset first threshold voltage and output a set signal from a determination output terminal when the first power generation voltage exceeds the first threshold voltage, a first photovoltaic element connected between the first input terminal and a grounding point in a forward direction and configured to output a first power generation voltage to the first input terminal according to photovoltaic power when light is radiated, and a feedback resistor inserted between the first input terminal and the determination output terminal.

An example embodiment includes a playback device comprising a wireless communications interface including a wireless (e.g., a radio frequency (RF) antenna), a capacitive sensor comprising an electrode that is coupled to the RF antenna, one or more processors, and a data storage having stored therein instructions executable by the one or more processors to cause the playback device to perform operations. The operations include operating the playback device in a first power state, detecting that an object is in proximity to the capacitive sensor, and in response to detecting the object, adjusting operation of the playback device from the first power state to a second power state.
