An actuating apparatus having a signal transmitter and a mechanical operating element, wherein the mechanical operating element includes a first position that is stable over time and a second position that is stable over time, wherein the mechanical operating element, in the case of a movement from the first position that is stable over time into the second position that is stable over time, actuates the signal transmitter, and wherein the signal transmitter, upon actuation, causes a first signal change followed by a second signal change of an output signal, and an evaluation circuit detects an actuation of the mechanical operating element based on the first signal change and the second signal change.

A light guide body rotates integrally with an operation knob, has an incident surface that is a concavely curved surface recessed to a side opposite to a light source side, and rotates about a rotation shaft located so as to intersect the incident surface of the light guide body. The incident surface of the light guide body is a concavely curved surface recessed toward the side opposite to the light source (toward a Z1 direction) on a cross-section taken along an X-Z plane.

A switch assembly including an actuator assembly operable to magnetically latch a switch in a closed position, where the actuator assembly includes a cup member coupled to the drive rod opposite to the switch and an opening spring positioned within the cup member and being held in compression when the switch is latched closed, and where the cup member includes a central opening. The switch assembly further includes a scissor link having a first leg and a second leg pivotally attached at a pivot point, where one end of the first and second legs extend into the central opening and are rigidly attached to the cup member and an opposite end of the first and second legs extend through the cover, and where pulling the link away from the actuator assembly breaks the magnetic latch and opens the switch.

A multi-way circuit having a plurality of base modules may be used in multi-way schemes for lighting control devices. The multi-way circuit may operate with a controller and the base modules of a lighting control system to provide a fully functional, multi-way toggle circuit, even when the switches installed in the base module are not paired or in their off modes. The multi-way toggle circuit can be defined as follows: if any button in the circuit is pressed (indicating a desire to change the load state), then the load toggles its state between on and off.

An operating device includes: an operating section that rotates about a predetermined axis; and a shaft part to move integrally with the operating section. The shaft part has a first end and a second end projected in directions opposite from each other along the axis. A guide regulates movement of the shaft part in a radial direction. A first regulation part specifies a position of the shaft part in a thrust direction by contacting the first end of the shaft part. A second regulation part is press-contacted to the second end, such that the first end of the shaft part is made to contact the first regulation part. A locking part is arranged integrally with the second regulation part, and restricts the shaft part from separating from the guide, by contacting the second end.

Push button device for a motor vehicle, has: a mechanical and/or electric function controller with a first control state and a second control state; a push button element pressable from a disengaged state into a pressed state, wherein the function controller has the first control state when the push button element is in the disengaged state and the second control state when the push button element is in the pressed state, the push button element connected to the function controller by a first pivot arm mounted rotatably about a first axis of rotation and by a second pivot arm mounted rotatably about a different axis of rotation spaced apart from the first axis of rotation, wherein the first pivot arm and the second pivot arm are designed to be pivoted in an identical direction of rotation as a consequence of a movement of the push button element.
