An electromagnetic relay is provided. The electromagnetic relay includes a first port and a second port, a first coil and a second coil, a movable armature coupled between the first port and the second port constructed to connect and disconnect the first port and the second port, a switch circuit, and a coil control circuit. The switch circuit is constructed to connect the first coil to an external power source to induce the first coil to create a first magnetic field having a first direction and disconnect the first coil from the external power source to cause the first magnetic field to collapse. The coil control circuit is constructed to induce the second coil to create a second magnetic field having a second direction responsive to the switch circuit being in the second state, the second direction being opposite the first direction.
133 LIGHT-CONTROLLED POWER APPARATUS US12952189 2010-11-22 US20120126634A1 2012-05-24 Jui-Hsiung Wu
A light-controlled power apparatus includes an insulating housing, a plurality of conductive terminals and a light-controlled circuit. The conductive terminals are disposed in the insulating housing and partially stretch out of the insulating housing for connecting with an AC power supply. The light-controlled circuit is disposed in the insulating housing and includes a power module, a control module and a switch module having a relay and a driving circuit. The power module is connected with the conductive terminals for getting and dealing with an AC input voltage to output an output voltage. The control module includes a light-detecting unit for detecting environment illumination intensity and then sending out a corresponding first signal, a light-detecting power unit for regulating the output voltage and then providing a work voltage for the light-detecting unit, and a switch control circuit unit capable of getting a second signal reflecting standard illumination intensity.

In some embodiments, an apparatus includes a power supply to generate a supply current; at least one optoisolator coupled to the power supply and responsive to the supply current to generate a charging current; a capacitor, coupled to the at least one optoisolator, to build up a charge in response to the charging current; and an actuating switch, coupled to the capacitor, to release the charge from the capacitor to generate a relay actuating current.

136 Circuit device dedicated in remote control switch US10632163 2003-08-01 US20050025480A1 2005-02-03 Chung-Kai Yeh
A circuit device dedicated in a remote control switch comprises the following elements. A voltage conversion circuit serves for converting AC input current to DC current. A photo sensor serves for sensing a laser light and receiving the DC current from the voltage conversion circuit. A switch button generates a trigger signal as the photo sensor senses an input laser light. A signal integrated circuit is turned on as the signal integrated circuit receives the trigger signal from the switch button. A flip-flop is capable of changing state as the signal integrated circuit is turned on. A relay serves for changing the operation state when the relay receives an input signal from the signal integrated circuit, thereby, the electric device connected to the flip-flop can be switched on or off when the flip-flop changes state.
137 Optically controlled MEM switches US09978314 2001-10-15 US06639205B2 2003-10-28 Tsung-Yuan Hsu; Robert Y. Loo; Greg Tangonan; Juan F. Lam
An optically controlled micro-electromechanical (MEM) switch is described which desirably utilizes photoconductive properties of a semiconductive substrate upon which MEM switches are fabricated. In one embodiment the bias voltage provided for actuation of the switch is altered by illuminating an optoelectric portion of the switch to deactivate the switch. In an alternative embodiment, a photovoltaic device provides voltage to actuate the switch without any bias lines at all. Due to the hysteresis of the electromechanical switching as a function of applied voltage, only modest variation of voltage applied to the switch is necessary to cause the switch to open or close sharply under optical control.

139 Light relay with adjustable core and contact gap US816551 1992-01-02 US5434475A 1995-07-18 Jeff D. Walters; Paul M. Buonpane
An outdoor lighting control includes a photosensor responsive to ambient outdoor light and an alternating current relay with a pair of contacts movable between make and break positions. The relay includes a contact actuating arrangement that responds to the photosensor and alternating current bias the contacts into a make position and move the contacts electromagnetically into a break position. The contact actuating arrangement includes a coiled extension spring for moving the contacts into the make position and a resilient armature which biases the armature toward the break position. The spring and armature have respective resiliences sufficiently stiff and responsive to the alternating current to limit chatter in the contacts during passage from the make position to the break position to 15 milliseconds when the photosensitive means senses a transition between dark and daylight.
140 Snap-acting normally closed AC relay US927596 1992-08-10 US5260677A 1993-11-09 John G. Gamble
A normally closed AC relay with a stator core with primary and shaded poles, a pivotal clapper, an elongated leaf spring fixed to the clapper providing a clapper return spring and a clapper overtravel spring extending radially outwardly from the outer end of the clapper, the overtravel spring being substantially narrower than the rest of the leaf spring to reduce the weight and moment of inertia of the overtravel spring and the complete clapper assembly, the overtravel spring having a spring rate significantly greater than the return spring and both the overtravel spring and clapper assembly having a natural frequency significantly greater than twice the frequency of the AC source so that the clapper is actuated to open the relay without incipient switch chatter.
