This push-button switch is bipolar, can control two functions separately or control a function simultaneously.
Described lid and pedestal fastening place have increased escapement, to prevent that the client from installing or product is thrown off by external force effect situation lower cover and pedestal.
Compared with prior art, the utlity model has following advantage:
1, the scope of application is wide: the controllable load scope is big, can control less than the resistive load of 3500W with less than the inductive load of 1500W; Can be used as the double break safety switch and use, also can be used as glass control switch and use, can also be as gate controlled switch or the like purposes.
2, fail safe is higher: this switch is bipolar, can control two circuit separately, also can use this two-way independent circuits to control a function simultaneously; When safety switch uses; So, even wherein one the road break down, another road can also play a protective role, and both being equivalent to has double protection, and fail safe is higher.
3, installation is more convenient: this switch directly adopts two screws to utilize the elliptical aperture of base and lid to fix, and installs more convenient.
4, more economical: as to adopt two sensitive switches when comparing double break, the utlity model has and take up room for a short time, install more conveniently, need not other design driving mechanism, so also more economical.
Description of drawings
Fig. 1 is the structural representation of the normally open push button switch of the utility model;
Fig. 2 is the structural representation of the normally closed push button switch of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
As shown in Figure 1, a kind of low-cost bipolar hilted broadsword push-button switch comprises push rod 1, pedestal 2, lid 3, slide block 4, moving contact 5, movable contact spring 6, short quiet pin 7, back-moving spring 8, guide rod 9, quiet contact feet 10, extension spring 11, fixed contact 12; Push rod 1 is installed on pedestal 2 tops, and guide rod 9 is installed on pedestal 2 bottoms, is positioned at the below of push rod 1; Back-moving spring 8 is socketed on the guide rod 9 and is connected with push rod 1, and quiet contact feet 10 is positioned at the both sides of guide rod 9, and an end is fixed on the support of pedestal 2; The other end extends to outside the pedestal 2, and support 13 is installed on the pedestal 2, and fixed contact 12 is fixed on the quiet contact feet 10; Short quiet pin 7 is positioned at the outside of quiet contact feet 10, and an end is connected with movable contact spring 6, and an end extends to outside the pedestal 2; Movable contact spring 6 is stuck in slide block 4 grooves, and moving contact 5 is fixed on the movable contact spring 6, and extension spring 11 1 ends collude in the hole of movable contact spring 6; The other end colludes in the hole of short quiet pin 7, slide block 4 and push rod 1 tiltedly carve support and connection, pedestal 2 and lid 3 are fastened and connected through button bit.Moving contact 5 and movable contact spring 6 riveted and fixed.
The utility model push-button switch function can be the two poles of the earth hilted broadsword (Double pole single throw NO) normally open push button switch or the two poles of the earth hilted broadsword (Double pole single throw NC) normally closed push button switch.
With the normally open push button switch is example, as shown in Figure 1, push rod 1 is not being applied under the external force situation, and switch is in off-state.If to push rod 1 applied thrust; Thrust overcomes the elastic force of back-moving spring 8, and behind the push rod 1 inside motion certain distance, push rod 1 can break away from the supporting role to slide block 4; This moment, two slide blocks 4 were owing to receive inwardly motion under extension spring 11 tension; Inwardly overturn thereby drive the movable contact spring 6 that is stuck in the slide block slot, contact with fixed contact 12, make switch connection up to moving contact 5.If cancel the thrust that puts on the push rod 1, push rod 1 is tiltedly carved by utilization under the effect of back-moving spring 8 two slide blocks 4 to be pushed open outward, outwards overturn thereby drive the movable contact spring group 6 that is stuck in the slide block slot, and moving contact 5 disengages with fixed contact 12, makes the circuit disconnection.
With the normally closed push button switch is example, and as shown in Figure 2, then switching function is just opposite; Be to be in on-state under the switch free state; When push rod 1 was applied external force, the effect of tiltedly carving of slide block 4 drawn stems is outwards motion down, outwards overturn thereby drive the movable contact spring 6 that is stuck in the slide block slot; Moving contact 5 disengages with fixed contact 12, and circuit is broken off; If discharge thrust; Push rod 1 receives to move upward under the effect of back-moving spring 8 behind the certain distance; Push rod 1 can break away from the supporting role to slide block 4, and two slide blocks 4 inwardly overturn thereby drive the movable contact spring 6 that is stuck in the slide block slot owing to receive inwardly motion under extension spring 11 tension at this moment; Contact with fixed contact 12 up to moving contact 5, make switch connection.
The sliding block material of the utility model can use fire retardant plastic, also can use metal material, to increase product useful life; Lid has increased escapement with pedestal fastening place, to prevent that the client from installing or product is thrown off by external force effect situation lower cover and pedestal.
The utility model can control load scope bigger, switch can load power less than the resistive load of 3500W with less than the inductive load of 1500W.Switch over travel is bigger, and normally open push button switch is connected stroke and is about 3.2-5.0mm, and total kilometres reach 12mm, and normally closed push button switch breaks off stroke and is about 2-4.0mm, and total kilometres reach 8mm.
The utility model push-button switch is bipolar, can control two functions separately, for example one the tunnel controls alternating current circuit, another road control DC circuit; Also can use this two-way independent circuits to control a function simultaneously, when safety switch used, even so wherein one the road break down, another road can also play a protective role, and both being equivalent to has double protection, and fail safe is higher.
The utility model is mainly used in:
1, cold and hot liquids is drunk equipment, and as cup control safety switch, cold and hot liquids is to people's injury with to the damage of equipment when preventing misoperation;
2, household electrical appliance, as gate controlled switch, the control apparatus interior light, and close the electrical equipment running, prevent damage to the people; For example: disinfection cabinet, refrigerator or the like;
3, miscellaneous equipment, as the safety switch of safty shield, when opening protective cover, no matter closing device whether, equipment all can be cut off the electricity supply, to guarantee personal security.
