A dual switch for selective removal of a recording medium from a compound device is so exactly sized and shaped that are exact switching action may be assured. Two switches are on a base plate, and a button is capable of selectively actuating either switch to take a recording medium out of the slot. The button has resilient member responsive to removal of pressure from the button for returning to its original position. The button can be of seesaw, slide or rotary type.

A switch assembly and method of switching a load between a first power source and a second power source that maintains a desired sequencing of the making and breaking of both the neutral and power connections in response to a single user input. The switch assembly includes an actuator that is movable between a first position and a second position and a first movable element and a second movable element that are operably coupled to one another and the actuator. A positive switch contact arrangement is coupled with the first movable element and a neutral switch contact arrangement is coupled with the second movable element. The positive switch contact arrangement and the neutral switch contact arrangement comprise geometrically different constructions so that moving the actuator between the first position and the second position avoids an open neutral condition.

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 switching device includes a paddle actuator biased to a rest position and configured to pivot relative to a housing to a depressed position to engage an air-gap switch disposed within the housing. The air-gap switch is configured to change a first state of a load connected to the switching device upon engagement by the paddle actuator. The paddle actuator is defined by a pair of opposing long sides and a pair of opposing short sides and has at least one slot defined therein parallel to the pair of opposing short sides thereof and centrally disposed between the pair of opposing long sides thereof. A rocker actuator is disposed in the at least one slot defined in the paddle actuator and is configured to pivot relative thereto to engage at least one switch. The at least one switch is configured to change a second state of the load connected to the switching device upon engagement by the rocker actuator.

A safety switch has a housing, a conducting assembly, a switching assembly and a resilient member. The housing has an on-end and an off-end. The conducting assembly is mounted in the housing and has two conductors and a bimetal strip. The conductors respectively correspond to the on and off-ends and are attached respectively to two separated ends of a circuit. The bimetal strip selectively connects the conductors. The switching assembly has a rocker and a connecting arm. The rocker is mounted pivotally on a top of the housing. The connecting arm connects the rocker and a contacting end of the bimetal strip. The resilient member is mounted between the on-end of the housing and the rocker to stably position the rocker when the circuit is on or off.

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.
