A load control device may be configured to provide a user interface for controlling the intensity and/or color of one or more lighting loads. The user interface may include separate actuation members for setting the intensity and/or color of the lighting loads. The user interface may include one actuation member configured to operate in an intensity and/or color control mode. The control mode of the actuation member may be set via a button, a lever, a rotary switch, a rotary knob, etc. The user interface may include a touch sensitive element capable of sensing a user's touch and translate the touch into a control signal. Feedback may be provided on the user interface to indicate the type of control being adjusted and/or amount of control being applied to the lighting loads.

A heat destructive disconnecting switch comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. The overheating destructive member is formed as an integral body on a limiting member, and a first elastic member is compressed to between a contact member and the overheating destructive member, thereby providing the first elastic member with a first elastic force. The second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is smaller than the second elastic force, causing the movable conductive member to disconnect the first conductive member from the second conductive member to achieve a protective effect from overheating.

Problem To be capable of specifying an operation of a knob. Solution A switch 1 includes an operation detecting portion 7 which detects an operation of the knob 5. The operation detecting portion 7 includes a movable member 6 which displaces in association with the operation of the knob 5, a through hole 62a which penetrates through a light shielding portion 62 of the movable member 6 in a thickness direction thereof, one optical source 15 which is provided on one side of the movable member 6 in the thickness direction, a light guiding path 9A which is provided on the other side of the movable member 6 in the thickness direction, and two light receiving elements 10A, 10A which are attached to the light guiding path 9A. The light guiding path 9A is arranged in a position of being capable of receiving light emitted from the optical source 15 through the through hole 62a when the movable member 6 is arranged in a predetermined position by the operation of the knob 5.

An electrical equipment for an electrical installation is connected to an electrical grid, and has at least: a primary functional module (2) suitable for carrying out a current interruption function, and an additional functional module (5) for carrying out at least one function requiring a power supply. The function of the additional functional module (5) is a function requiring a power supply except for an indicator light lighting function.

A safety switch for an automated industrial plant includes a swivel-mounted rocker having at least one rip cord connector and at least one accelerometer arranged on the rocker. Swivel movement of the rocker is identified by evaluating signals of the accelerometer.

An operation lever of a work vehicle has the operation surface including: a connection portion; a front operation surface extending obliquely so that a height from a reference plane increases from the connection portion toward the forward side of the connection portion in a cross-sectional view including a front-rear directions and a front-side edge of the operation surface being defined as a front-side top portion; and a rear operation surface connected to the front operation surface, extending obliquely so that a height from the reference plane increases from the connection portion toward the backward side of the connection portion and a rear-side edge of the operation surface being defined as a rear-side top portion. A length in front-rear directions along the reference plane in the front operation surface is larger than a length in the front-rear directions along the reference plane in the rear operation surface.

A heat destructive disconnecting switch, comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. A first elastic member and the second elastic member act on an operating member. The first elastic member is compressed and provided with a first elastic force, and the second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is diminished or vanishes, causing the second elastic force to be larger than the first elastic force. Consequently, the movable conductive member disconnects the current conducting state between the first conductive member and the second conductive member, thereby achieving a protective effect from overheating.

An electrical switch with identifying features. Embodiments include a toggle assembly for an electrical switch that comprises a switch body including a contact mechanism configured to control an electrical circuit. A movement of the toggle assembly from a first position to a second position is mechanically communicated to the contact mechanism. The toggle assembly can also include a user-operable actuator portion elongated between the switch engagement portion and a front end of the toggle assembly enabling a user to pivot the toggle assembly from the first position to the second position. Embodiments include an interchangeable tile removably coupleable to the toggle. The interchangeable tile can comprise an identifier. Embodiments include an illuminating element.
