A multi-command trigger switch includes a rotary switch, a rotary casing and a trigger element. The rotary switch includes a base and a rotary disc coupled with the base and movable on a swivel locus against the base. The base and the rotary disc are interposed by a housing space to hold a rotary trigger assembly and a depressing trigger assembly. The rotary trigger assembly outputs a first trigger signal while moving on the swivel locus. The depressing trigger assembly outputs a second trigger signal while moving on a vertical locus. The rotary casing and the rotary switch define a movement space therebetween to hold the trigger element. The base and the depressing trigger assembly confine movement of the depressing trigger assembly through a positioning notch and a confining rib. The depressing trigger assembly and the trigger element include confine the trigger element from rotating against the rotary casing.

Abstract

A multi-instruction switch for enhancing electrical insulation is provided. The multi-instruction switch includes a housing, a common pin and a switching pin set. The housing comprises an accommodating space which includes a conductive elastic plate moving back-and-forth and a support rack therein. The conductive elastic plate includes a normal connection section and a switching connection section. The support rack includes a limiting track. The common pin is normally in electrical contact with the normal connection section in the housing. The switching pin set includes a first pin having a contact section and a second pin having a trigger section. The limiting track includes a first insulation plate, a second insulation plate, and an insulation space between the first and second insulation plates. As such, the present invention enhances the insulation effect by the first and second insulation plates and the insulation space located at the limiting track.

Abstract

A transformer without coil racks includes a winding set, multiple conductive plates and an insulation mounting sheet. The winding set includes a coil portion and a magnetic core set running through the coil portion. The magnetic core set includes at least one inner magnetic core portion and at least two outer magnetic core portions that are spaced from each other by a gap. Each conductive plate includes a connecting section and two extended arms connected to two ends of the connecting section and running through the gap. The insulation mounting sheet includes multiple retaining slots corresponding to the gap to allow the extended arms to pass through and multiple retaining portions each being formed between two neighboring retaining slots to prevent the extended arms from contacting each other. The conductive plates run through the retaining slots and are confined by the retaining portions from moving.

Abstract

An enhanced withstand voltage micro switch includes a base and a cap covering the base. The cap has a press element movable up and down. The base has a conductive member depressed by the press element and a connecting section extended upwards. The base also includes a first contact, and a second contact extended from the connecting section and located above the first contact. The conductive member is swung during up and down movement of the press element to connect with the first or the second contact. The connecting section has an isolation portion jutting sideward between the first and second contacts to prevent generation of a conductive layer caused by connection of the conductive member with the first and second contacts on the connecting section. Thus secured insulation can be formed between the first and second contacts to withstand a higher voltage test.

Abstract

An enhanced returning elasticity micro switch includes a base and a cap mounted thereon to form a housing compartment therebetween. The base is run through by a first pin and a second pin. The first pin has an anchor portion in the housing compartment to couple with a conductive member. The conductive member has a lower contact portion and swings when being pressed. The second pin has a first contact in the housing compartment. The first contact has an inclined surface connected to the lower contact portion during swing of the conductive member. The inclined surface is located at an elevation tapered towards the anchor portion. Hence the contact area between the conductive member and second pin increases, and adhesion force between the conductive member and second pin during power transmission decreases. Returning elasticity of the conductive member increases, and resistance against depression of the conductive member decreases.

Abstract

A luminous micro-switch mainly includes a case which holds a depressing member and at least a first pin and a second pin inside that are spaced from each other. There is a bridging member interposed between the two pins and the depressing member to form electric connection with the first pin in regular conditions and output a signal when the bridging member is connected to the second pin due to depressing of the depressing member. The depressing member has a depressing end which has a holding trough to hold a lighting element which has two conductive terminals to receive electric power to generate light. By holding the lighting element in the holding trough the size of the micro-switch can be made smaller to be used on smaller electronic devices to overcome the bulky problem of conventional micro-switches caused by disposing the lighting element beneath the depressing member.
