Abstract:
Provided are a standby power cut-off device for automatically cutting off standby power according to power-on/off of an electronic product and a control method for the standby power cut-off device. By providing an electronic product to which the standby power cut-off device and the control method therefor are applied, the present invention can efficiently cut off standby power by using an existing general outlet without a need to use an outlet having a separate function added thereto. Moreover, the present invention automatically cuts off the standby power according to power-off of the electronic product without unplugging the electronic product, thereby maximizing user's convenience.
Abstract:
The present invention discloses a relay switch arrangement for a toaster, the arrangement has an actuating member releasably engaged to the engaging metal positioned above the electromagnet, and shifted between a power-on position and a power-off default position. A homing spring is provided biasing against the actuating member for maintaining the actuating member in the power-off position. Electrical contacts are respectively provided onto a pair of power slabs for selectively completing the circuit, wherein in the power-on position, the actuating member drives two contacts approach with each other complete the circuit to charge the electromagnet attracting the engaging metal, in the power-off default position, the circuit is powered off enabling the electromagnet to release the engaging metal, the homing spring will upwardly push the actuating member thus driving the engaging metal tilt up so as to disengage the pair of contacts for security purposes.
Abstract:
A dual mode switch is provided in accordance with the present invention. The switch is selectively and mechanically cycled between a first state and a second state while power is provided to a biasing member. The switch is selectively cycled from the second state to the first state by stopping the supply of power to the biasing member.
Abstract:
A switch device including a switch operation shaft movable between a plurality of operation positions for setting a control amount for an apparatus. A follower is driven to follow the movement of the switch operation shaft. An attraction member generates magnetic force to attract the follower so that the follower becomes immovable and to hold the switch operation shaft at a single operation position.

Abstract:
A timed switch has a housing member, an output connecting leg connected to an appliance, and a circuit board including both a timing device and an electromagnet. The output connecting leg is electrically connected to the circuit board, and has a front end movable member disposed behind the front wall of the housing member. A control button is pivoted to the outer side of the front wall from a middle with an upper and a lower pushing protrusions passing through the front wall to abut an upper part and a lower part of the movable member respectively. A first, and a second input connecting legs are provided, which are connected to the power, and the second further to the circuit board. A power-on end of the button is pushed to make the upper part, and the lower part of the movable member to contact the first leg and the electromagnet respectively; thus, the appliance and the circuit board are energized, and the electromagnet attracts the lower part of the movable member thereto so as to make the upper part continue to contact the first leg to complete the circuit. At the same time, the timing device is actuated such that the appliance can be automatically turned off at a preselected time after it has been actuated.

Abstract:
A power shut-off connector has contact terminals 55, 56 coming into sliding contact with a moving pin 43, a mating portion 54 and a retaining member 45 of the moving pin, an urging member 62 and a driving member (solenoid) 42 with respect to the moving pin. One side of a locking member 45 as a retaining member is coupled to the plunger 44 of a solenoid 42 and the other side is pivotally supported with a bracket 46 and besides the locking member is mated with the mating portion. The solenoid 42 is provided with a second plunger 150 symmetrically and by coupling a second locking member 151 to the plunger 150, the plunger may be mated with the second mating portion 65 of the moving pin 43. In place of the locking member 151, the plunger 44 may be pulled by means of a weight and a folded wire. A mating portion 54 is provided at the leading end of the moving pin 43, and the locking member 45 and a bracket are disposed on the projecting side of the moving pin so as to dispose the solenoid on the side of the moving pin. The locking member is provided with a plastic tip 53. A housing portion for housing a coil spring 62 is provided in the moving pin.
Abstract:
An electrical switch has a movable contact 15 and a fixed contact 14. A member 26 can move the contact 15 to make or break the switch. A latch including a movable device controls the initial movement of member 26 but the member 26 then moves independently of the latch. The device can be moved to release the latch either manually (by 31) or by another mechanism. This other mechanism can be an electromagnet 41; it also can be an inertia body 51 releasable from a rest position in response to excessive acceleration.
Abstract:
A rotary switch adapted to be integrated into a push-to-start electrical control for a clothes dryer or the like employs a rotatable and axially translatable operator having an outwardly extending arm supporting a downward finger which travels across a pivotally mounted and downwardly arcuate lever to open and close contacts mounted on one end of the lever with rotation of the operator. Stops on rotation ensure that the finger is positioned on the lever so as to provide positive biasing of the operator to its end positions. The armature of a relay is actuated by a second arm from the operator contacting the armature within a triangle formed by the electromagnet coil and pivot supports preventing de-stabilization of the armature by the operator. Assembly of the relay to a base of the switch is provided by integrally molded hooks receiving tabs which cover holes necessary for the hook's manufacture. The operator is supported in a socket having a thin bottom wall that breaks free upon axial impact against the operator such as otherwise would be expected to damage the integrity of the switch housing.
