Abstract

A centrifugal electrical switch comprises an insulating casing, a fixed contact, a moving contact, a centrifugal block, a spring, a first electrode and a second electrode. The moving contact is welded on the centrifugal block; one end of the spring is connected with the centrifugal block and the other end of the spring is connected with the first electrode; and the fixed contact is connected with the second electrode. A centrifugation device rotates to drive the moving contact on the centrifugal block to contact the fixed contact so as to turn on a circuit. When a rotating speed of the centrifugation device is lower than a certain speed, the circuit is turned off under effects of the spring pulling force. According to the technical scheme of the utility model, the defect that a conventional switch cannot move at a certain rotating speed is overcome, and the circuit is easy to turn on/off when the on-off of the circuit is realized on basis of the rotating speed.

Description

A kind of centrifugal electric switch

Technical field

The utility model relates to a kind of electric switch, especially a kind of a kind of electric switch of realizing Push And Release by centrifugal rotation.

Background technology

At present, general electric switch is all fixed, and makes switch motion by craft or solenoid generation magnetic force, and sometimes we need switch to move when reaching certain rotating speed, but substantially do not have on the market this type of switch to sell.

The utility model content

Can't be implemented in the shortcoming of moving under the condition of certain rotating speed in order to overcome existing switch, the utility model proposes a kind of centrifugal electric switch with head it off, its good effect is: adopt a kind of centrifugal electric switch of the present utility model, can realize at needs the convenient Push And Release of realizing circuit of occasion of switch by rotating speed.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of centrifugal electric switch of the present utility model, formed by insulation crust, fixed contact, moving contact, centrifugal-block, spring, the first electrode, the second electrode, moving contact is welded on the centrifugal-block, spring is connected with centrifugal-block with an end, the other end is connected with the first electrode, fixed contact is connected with the second electrode, utilize the rotation of centrifugation apparatus, moving contact on the centrifugal-block is contacted with fixed contact, the realization circuit is connected, when the centrifugation apparatus rotating speed is lower than certain speed, under the effect of spring tension, realize that circuit disconnects.

The technical solution adopted in the utility model will cooperate accompanying drawing to elaborate in specific embodiments.

Description of drawings

The below is brief description of drawings.

Fig. 1 is a kind of centrifugal electric switch structure schematic diagram of the present utility model.

1. insulation crusts among the figure, 2. fixed contact, 3. moving contact, 4. centrifugal-block, 5. spring, 6. the first electrode, 7. the second electrode.

Embodiment

In the embodiment in figure 1, we further specify the utility model as example to implement a kind of centrifugal electric switch:

Fig. 1 is a kind of centrifugal electric switch structure schematic diagram of the present utility model, insulation crust 1 adopts plastic production among the figure, fixed contact 2 is positioned at the far-end (with respect to rotating shaft) of insulation crust 1, moving contact 3 is welded on the centrifugal-block 4, centrifugal-block 4 uses the good metal of conduction and makes, the requirement quality is suitable, spring 5 one ends are connected on the centrifugal-block, the other end is connected on the first electrode 6, can utilize dexterously spring as conductor, UNICOM's moving contact 3 and the first electrode 6, the second electrode 7 is connected with fixed contact 2, in the specific implementation, to require to determine according to the action rotating speed quality of spring strength and centrifugal-block 4, to guarantee under this rotating speed, electric switch energy normally closed, centrifugal electric switch by the above-mentioned requirements making, in use, can centrifugal electric switch of the present utility model be fixed on the centrifugation apparatus with screw, its spring terminal is to the axle of walking around, the fixed contact end is positioned at far-end, when centrifugation apparatus turned round, centrifugal-block 4 to the direction motion away from the axle center, made moving contact 3 contact with fixed contact 2 under the effect of centrifugal force, circuit turn-on, when the centrifugation apparatus rotating speed was lower than certain speed, under the effect of spring tension, moving contact 3 separated with fixed contact 2, circuit disconnects, realized the effect of centrifugal switch, the just this situation of normal open switch of certainly drawing among this figure need to be made the closed type centrifugal switch, only need to spring and moving contact switch, spring be worked as stage clip used just.
