A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may switch from controlling one characteristic of the electrical loads to controlling another characteristic of the electrical loads based on the position of one or more components of the load control device. Such a position may be manipulated by moving the one or more components relative to an idle position of the load control device. The load control device may be a wall-mounted device or a battery-powered remote control device.

A member has a first recess, a second recess, and a depression. The depression accommodates a movable member and a contact member. Positioned on a bottom surface of the first recess is a first fixture contact, whereas positioned on a bottom surface of the second recess is a second fixture contact. When a pressure receiving section of the movable member is pressed toward a bottom surface of the depression, the movable member is elastically deformed to separate a movable joint from the contact member. When the pressure receiving section is further pressed toward the bottom surface of the depression, the movable member is elastically deformed to separate the first movable contact from the first fixture contact and to separate the second movable contact from the second fixture contact.

To provide an input operation device capable of detecting, using a simple configuration, a first operation of touching an operation surface with an operation body and a second operation of pressing the operation surface with the operation body.

An input operation device 11 includes a detection value changing part 31, which changes a detection value of a capacitive sensor 12, and a supporting part 41, which supports a touch sensor part 21 in a state in which the detection value changing part 31 and the touch sensor part 21 are separated from each other. The detection value changing part 31 is arranged on a back surface 24 side opposite to the operation surface 22 of the touch sensor part 21, and changes the detection value depending on contact with the detection part 23. The supporting part 41 includes an elastically shape-changeable part 42, which elastically changes shape so as to bring the detection part 23 into contact with the detection value changing part 31 in response to pressing of the operation surface 22. The capacitive sensor 12 of the input operation device 11 generates a first detection value indicating a first operation of touching the operation surface 22 and a second detection value indicating a second operation of pressing the operation surface 22 toward the detection value changing part 31.

A foot pedal for controlling a medical device, in particular a dental device, including a housing with a housing base, a cover element which is mounted so as to be vertically displaceable with respect to the housing base along an actuating direction and so as to be inclinable with respect to the housing base, a first switch for initiating a first functionality on the medical device and a second switch for initiating a second functionality on the medical device, and an actuating device which is vertically displaceable along the actuating direction and which actuates the first switch during a movement in the actuating direction within a first height offset section and actuates the second switch within a second height offset section, the actuating device being configured in such a way, in that it is in a first state in the first height offset section and in a second state in the second height offset section, where the foot pedal being configured such that, at a predeterminable angle of inclination of the cover element, the actuating device is always arranged within the first height offset section.

A key structure includes a keycap, a supporting plate, a connecting element, a circuit board and an elastic element. The circuit board is disposed on the supporting plate. The circuit board includes a switch element. A first switch unit of the switch element is formed on a top surface of a first film layer of the circuit board. A second switch unit of the switch element is formed on a top surface of a second film layer of the switch element. When the keycap is depressed in response to an external force, the elastic element is subjected to deformation. Consequently, the first switch unit and the second switch unit are selectively turned on to generate a first key signal and a second key signal.

The switch opening-closing mechanism, which makes it possible to increase a contact force so as to improve a vibration resistance, includes a sliding part, a second movable piece, and a second fixed contact. In a case where an amount of movement of a sliding part reaches a second retraction amount, the second movable piece comes into contact with the second fixed contact due to a spring force applied to the second movable piece. In a case where the amount of movement of the sliding part reaches a third retraction amount which is larger than a second retraction amount, the sliding part presses the second movable piece against the second fixed contact.
