An overload protection switch includes a main body and a press button. Several terminals, a conductive plate and other components are arranged in the main body. By means of switching the press button, the switch is switchable between an on state and an off state. In case of overload, the conductive plate will separate from one of the terminals to switch off the switch. The components arranged in the main body will not hinder the conductive plate from separating from the terminal. When switching on the switch, the conductive plate resiliently contacts the terminal. In case of overload, the conductive plate separates from the terminal to switch off the switch so as to provide overload protection effect.

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.

A remote-controlled switch cover assembly is described for converting an existing rocker switch into a remote-controlled switch. The remote-controlled switch cover assembly receives a wireless signal to actuate the standard rocker switch and, in response, activates an electric motor that causes a gear train to turn in a first direction. This causes a wiper to engage an under-surface of a tilt plate located above the standard rocker switch and, in response, an opposing end of the tit plate depresses the standard rocker switch.

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.

A switch includes a body with a switch member on a top thereof, an extension extends from an underside of the switch member, and a substantially inverted L-shaped slot is defined through the extension. Two terminals extend through a bottom of the body, in which one of the terminals is fixed with a contact plate. The contact plate has a tongue with a free end, which contacts the other terminal when the circuit is ON, and is separated from the other terminal when the circuit is OFF. An operation member has a first end movably engaged with the slot and a second end connected with the contact plate. A positioning member having a first end pivotally connected to an inside of the body and a second end biasing the first end of the operation member. Under the current overload condition, the switch member is pivoted by a torsion spring to the OFF position.
