Fig. 2 is the structural representation of normally closed push button switch of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of bipolar single-knife button switch, comprise 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, guide rod 9 is installed on pedestal 2 bottoms, be 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, quiet contact feet 10 is positioned at the both sides of guide rod 9, one end is fixed on the support of pedestal 2, and the other end extends to outside the pedestal 2, and support 13 is installed on the pedestal 2, 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, 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, and 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 by button bit.Moving contact 5 is fixing with movable contact spring 6 riveted joints.
Push-button switch function of the present invention 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.
Take normally open push button switch as example, as shown in Figure 1, push rod 1 is not being applied in the external force situation, switch is in off-state.If to push rod 1 applied thrust, thrust overcomes the elastic force of back-moving spring 8, 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 be subject to inwardly motion under the extension spring 11 pulling force effects, inwardly overturn thereby drive the movable contact spring 6 that is stuck in the slide block slot, until moving contact 5 contacts with fixed contact 12, make switch connection.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.
Take normally closed push button switch as example, 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 lower outwards motion of the slide block 4 drawn stems effect of tiltedly carving was 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 disconnected; If release thrust, push rod 1 is subjected 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, this moment, two slide blocks 4 were owing to be subject to inwardly motion under the extension spring 11 pulling force effects, thereby driving the movable contact spring 6 that is stuck in the slide block slot inwardly overturns, until moving contact 5 contacts with fixed contact 12, make switch connection.
Sliding block material of the present invention 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 Acting situation lower cover and pedestal.
The present invention can control load scope larger, switch can load power less than the resistive load of 3500W with less than the inductive load of 1500W.Switch over travel is larger, 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 disconnects stroke and is about 2-4.0mm, and total kilometres reach 8mm.
Push-button switch of the present invention is bipolar, can control separately two functions, for example one the tunnel controls alternating current circuit, another road control DC circuit; Also can control simultaneously a function with this two-way independent circuits, when using in particular as safety switch, 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 present invention 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 the damage to the people; For example: disinfection cabinet, refrigerator etc.;
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.
