Provided are a switch module and a push switch that have a soft sensation when pressed. A push switch and a switch module have a substrate, a first fixed contact point disposed on the substrate surface, a second fixed contact point disposed around the first fixed contact point on the substrate surface, a convex dome-shaped upper spring disposed on the substrate surface so that an end part is in contact with the second fixed contact point, the upper spring being pressed so as to invert the dome shape and to establish conduction between the first fixed contact point and the second fixed contact point, and a lower spring disposed below the upper spring, the lower spring adjusting the operation load applied to the upper spring during inversion of the dome shape.

A detachable keyswitch mechanism includes a base and a keyswitch. The base includes a bottom plate and a lateral plate bent from the bottom plate. The base further includes an opening structure disposed on the lateral plate, a first rotating portion disposed between the bottom plate and the lateral plate, and a constraining portion disposed on the bottom plate. The keyswitch includes a body rotatably disposed inside the opening structure, a second rotating portion disposed on an upper side of the body and pivotably connected to the first rotating portion, a recovering portion connected to a low side of the body, and an actuating portion disposed on a surface of the body. An end of the recovering portion opposite to the body contacts against the constraining portion. The actuating portion is adapted to actuate a switch disposed on the base when the keyswitch rotates relative to the base.

A switching system may include a body and a set of key elements. The body may be electrically connectable to a first electrical device and a second electrical device, and may have a keypad with key element attachment features to which the key elements can be attached. The key elements may be attachable in various positions and/or combinations on the keypad. The key elements may include one or more buttons of various sizes and/or a rocker. The keypad may have multiple positions to which key elements can be attached, with larger key elements requiring multiple positions. The key element attachment features may be domes, which may be inserted into holes in tabs extending from the key elements to pivotably attach the key elements to the keypad. Each key element may be retained on the keypad independently of any other component aside from the keypad and the key element.

An apparatus includes communication circuit; an actuator electrically coupled with the communication circuit; and a switch engagement component mechanically coupled with the actuator. The apparatus is configured for mounting adjacent to a switch (e.g., a rocker switch, a toggle switch, a button switch, etc.). The communication circuit is configured to activate the actuator in response to one or more instructions received by the communication circuit. The actuator is configured to rotate the switch engagement component. Rotating the switch engagement component while the switch is in a first state places the switch in a second state that is distinct from the first state.

A push switch includes a housing, a fixed contact member, a movable contact member, and a first pressing member. The housing includes an opening and a compartment, the movable contact member includes a dome that protrudes toward the opening and is invertible, and the first pressing member includes a first fulcrum portion, a first load portion, and a first effort portion. The first fulcrum portion is disposed on one side of the first pressing member to contact the housing, the first load portion is disposed on another side of the first pressing member to press the movable contact member, and the first effort portion is disposed between the first fulcrum portion and the first load portion. Upon the first effort portion being pressed through the opening, the first load portion presses and inverts the dome of the movable contact member, and the movable contact member contacts the fixed contact member.

The invention relates to a device (2) for detecting manipulation on an object comprising an actuating switch (22) which has a snap-action disk (220) which can be switched between a first position and a second position, and an actuating element (21) which has a body (210) and an actuating stud (211), projecting from the body of the actuating element (21), for acting on the snap-action disk (220), wherein the actuating stud (211) has a first stiffness. According to the invention a contact element (213), arranged on the actuating stud (211), acts on the snap-action disk (220), wherein the contact element (213) has a second stiffness which is greater than the first stiffness.

A push switch contains a case including a housing space having an upper-opening and including fixed-contacts disposed on a bottom of the housing space, a movable contact member disposed in the housing space configured to deform in response to receiving pressure applied from above, and contacting the fixed-contacts upon defoming in response to the received pressure, and a pushing member disposed on the movable contact member and configured to transmit the received pressure to the movable contact member. The movable contact member includes a pair of first-linear edges, wherein the pushing member includes a plurality of projecting-pressing portions disposed on a bottom surface of the pushing member facing the movable contact member, and wherein the plurality of pressing portions is disposed on the bottom surface at positions not overlapping a straight-line that passes through a center of the movable contact member and intersecting each of the pair of first-linear edges.

A push switch according to the present disclosure includes: a case including a recess; a fixed contact member including a fixed contact disposed in the recess; a movable contact member including a movable contact disposed in the recess; a protective sheet disposed in a first direction from the recess and covering the recess; and a rib disposed on the protective sheet. The protective sheet includes: a pressing portion; a fixed portion fixed to the case; and an intermediate portion located between the pressing portion and the fixed portion as viewed in the first direction. As the pressing portion of the protective sheet is pressed along the first direction, the movable contact member deforms by force received from the protective sheet. The movable contact touches the fixed contact as a result of the deformation of the movable contact member.

A portable radio includes a printed circuit board, a frame positioned in front of the printed circuit board, a speaker positioned within the frame, a support platform positioned in front of the speaker and the frame, a button positioned in front of the support platform, and electrical components linked between the button and the printed circuit board. The button is movable between a first position where an electrical signal is sent through the plurality of electrical components to the printed circuit board, and a second position where the electrical signal is interrupted.

A control device includes a button assembly having one or more buttons and a button carrier that includes a plurality of resilient, independently deflectable spring arms. The control device may be configured as a wall-mounted keypad to control a load control device, or as a thermostat to control a temperature regulation appliance. The button carrier may be configured to prevent interference between the buttons during operation of the control device. The button assembly may be captured between a faceplate of the control device and a housing that is attached to a rear side of the faceplate. The control device may include one or more button retainers that are attached to the buttons and that are configured to align respective outer surfaces of the buttons relative to each other, and relative to the faceplate of the control device, when the buttons are in respective rest positions.
