A switching device includes a housing and a paddle actuator operably coupled to a front face of the housing and adapted to control a state of a load. The paddle actuator has a pair of opposing long sides and short sides and is configured to pivot about a hinge disposed proximate to one of the short sides of the paddle actuator. At least one component is disposed adjacent to the short side of the paddle actuator that is disposed proximate to the hinge and is configured to sense at least one condition. A control element is configured to control at least one of a sensing range and a sensitivity of the at least one component. The paddle actuator occupies at least 50% of the front face of the housing and the at least one component substantially occupies the remainder of the front face.

A switch module of built-in anti-surge disconnection structure mainly comprises an overcurrent protection switch and has anti-surge and disconnection structures ingeniously built inside a fire-proof and heat-resisting housing. The present invention comprises a switch area formed by a binary alloy conductive spring leaf and two connecting points, an anti-surge area formed by at least one bare metal oxide varistor placed in the housing and a plurality of conductive plates, and a disconnection area formed by a spring element, a band, and a thermo-sensitive piece. When the connecting points in the switch area are contacting with each other—turning on the switch—and an overvoltage occurs, the temperature of the metal oxide varistor would suddenly rise up to a degree higher than a pre-determined number, melting the thermo-sensitive piece, loosening and displacing the band, thus ejecting the spring element and forcing the connecting points detaching from each other to turn off the switch, so as to ensure more of electricity safety.

A switch unit contains a case; a fixed contact members disposed on a bottom wall of the case; conductor plates rockably disposed on the bottom wall; driving bodies disposed on the conductor plates in a rotatable state in which the elevating movement thereof is allowed; a plate spring member for resiliently biasing the driving bodies; and a cover member for covering an upper opening of the case. The driving bodies are provided with pressed parts that protrude above the cover member. When the pressed part is driven to rotate laterally by the rocking operation of the operating knob, the driving body rotates, which causes the conductor plate to slide on the bottom wall. As a result, the switch unit is switched to its ON state.

Provided is a switch capable of easily, visually identifying the operation position of an operation handle. The switch is provided with a reverse handle 50 that is retained on the front side of an equipment body 1 so that the reverse handle can be rocked with respect to the equipment body 1 and changes a contact in the equipment body 1; and an operation handle 2 that is arranged in the opening window of a decorating plate that is connected to the front side of the reverse handle 50 and is attached to the front of a plate frame and has both ends that alternately perform the raising and falling operation by alternately pushing down both the ends. The operation handle 2 comprises an operation handle body 60 connected to the reverse handle 50, and a handle cover 80 that is deposited to the front side of the operation handle body 60 while the front of both the ends of the operation handle body 60 is exposed. The color of the operation handle body 60 is made different from those of the handle cover 80 and decoration plate.

A safety switch has a casing, a first circuit prong, a second circuit prong, a switch contact, a rocker, an arm and a latch. The first and second circuit prongs are mounted in and extend through the casing. The switch contact bends upward when temperature of the switch contact increases, is mounted on the first circuit prong and has a distal end selectively contacting the second circuit prong. The rocker is pivotally mounted on the casing and has a deactivating end and an activating end. The arm is formed on and protrudes down from the activating end and connects to the distal end of the switch contact. The latch is mounted in the cavity and selectively locks the arm to prevent the distal end of the switch contact from contacting the second circuit prong as the temperature drops. The safety switch may be used in severely cold environments.
