A switch and methods of assembling a switch. The switch may include a housing; a first terminal electrically coupled to a power source; a second terminal electrically coupled to a load; a contact having a first contact end and a second contact end, the contact being operable to be in a closed position, in which the first contact end engages the first terminal and the second contact end engages the second terminal such that the contact electrically connects the first terminal to the second terminal, and an open position, in which the contact does not electrically connect the first terminal and the second terminal; and a biasing member configured to bias the contact towards the first terminal and the second terminal, the biasing member being operable to apply a first biasing force proximate the first contact end and a second biasing force proximate the second connect end.

An rotary switch operating apparatus has a drive shaft and a first and a second drive element, the first drive element having a rotationally fixed coupling to the drive shaft, and the second drive element being rotatably mounted on the first drive element. The apparatus includes a spring coupling the first and the second drive element together with a spring action, a lock limiting rotational movements of the second drive element in a first rotation direction and a second rotation direction, opposite the first, and a releaser for canceling rotational movement limitation of the second drive element in pre-specified rotation positions of the first drive element. Latches bearing against the drive elements' guide sections are provided, the first drive element guide section having release sections as releasers and the second drive element guide section having two latch stops as locks. The latches can both lock and release the spring-operated movement of the second drive element.

A disconnector for photovoltaic applications having at least two modular contact boxes, each contact box having a box-like body coupled to a contiguous box-like body of a contiguous modular contact box. The box-like body forms a central seat that accommodates a rotatable contact and two peripheral seats, each of which accommodates a connection portion of a corresponding fixed contact that can be accessed from the outside of the modular contact box. The rotatable contact is able to rotate about the axis of the central seat with respect to the box-like body in order to engage the fixed contacts arranged with their connection portion in the peripheral seats or to disengage from the fixed contacts.

An operating panel device includes an operating ring, and a display device which is disposed to face a back surface of the operating ring. The display device includes a first portion, a second portion, and a third portion. The first portion is located inside the operating ring, and the second portion is located outside the operating ring. The third portion connects the first portion and the second portion. A display of the first portion changes in conjunction with a rotational operation applied to the operating ring.

An ignition switch assembly is configured to be operatively connected to a gas valve. The ignition switch assembly may include a first ignition contact and a second ignition contact. The first and second ignition contacts may be sized and shaped the same. A hub may be configured to be rotated within the ignition switch assembly. A rotation of the hub in a first direction causes a portion of the first ignition contact to engage the second ignition contact. Further rotation of the hub in the first direction or rotation of the hub in a second direction that is opposite from the first direction causes the portion of the first ignition contact to disengage from the second ignition contact.

A power mechanism, a switch, a power conversion apparatus, and a power supply system. The switch includes a contact component, a knob, and a power mechanism connected between the contact component and the knob. The power mechanism includes a fastening bracket, a knob connector, a contact connector, a transmission component, a trip unit, and a cradle. Both the knob connector and the contact connector are rotatively connected to the fastening bracket, and rotation centers of the knob connector and the contact connector are collinear. The transmission component is configured to implement power transmission between the knob connector and the contact connector. The trip unit is configured to receive a switch-off signal, to implement tripping of the trip unit and the cradle. The transmission component is driven to move by using the cradle, to separate the movable contact from the static contact, so that the switch is switched off.
