The top of the push handle is located at the top of the pedestal through the through hole of the upper side frame, and reinforcement is additionally provided with the push handle
Part.By setting reinforcer in push handle, push handle intensity is greatly improved, rather than rely solely on the strong of push handle plastic rubber material itself
Degree, so as to which push handle is not easy to break during stirring, it is relatively reliable to stir process.
Preferably, the reinforcer is pin, and the pin is embedded in the inner chamber of the push handle, the diameter of the pin
Equal to the diameter of the push handle inner chamber.Pin is brought into close contact with push handle inner chamber, is not easy to drop.
Preferably, it is additionally provided with thin film between the movable contact spring and the push handle.By setting the film, to pedestal
Movable contact spring in cavity carries out insulation blocking, avoids movable contact spring oxidation by air and can play a part of isolating dust.
Preferably, the movable contact spring includes five spring leafs, upper a connecting portion and a lower connecting portion, described five
Spring leaf includes middle springs piece and first to fourth spring leaf around the middle springs piece, is arranged outside the push handle
Have a push rod, the upper body of the push rod is located at the top of the pedestal, the bottom of the push rod be provided with described first to
One-to-one first to fourth convex closure of 4th spring leaf, first to fourth convex closure is located in the base cavity and difference
Contacted with first to fourth spring leaf, the bottom of the push handle contacts with the middle springs piece, the terminal include with
One-to-one first to fourth terminal of first to fourth spring leaf, intermediate terminal corresponding with the middle springs piece with
An and normal open terminal.By the distinctive design form of above-mentioned movable contact spring, push handle, push rod and terminal and its mutually match somebody with somebody
Close, a touch-switch is that may replace five traditional switches, and space interest rate is also improved while production capacity is lifted and is used, and is pushed away
Handle is internally provided with reinforcer, and without worrying that the problem of easy fracture occurs during the fiddling with of all directions in push handle, operation is more
Add flexible safe and reliable.
It is further preferred that first to fourth spring leaf forms square, the first to fourth spring leaf arrangement
In four angles position of square, the middle springs piece is arranged in the center of square.
It is further preferred that the quantity of the movable contact spring is two.So that convex closure, push handle, movable contact spring, each terminal
Between contact it is more sensitive, better reliability.
Preferably, the lateral surface of the pedestal is provided with the buckle of outwardly convex, and the lower edge of the upper side frame is provided with
The hole position being engaged with the buckle.Upper side frame is connected with substrate latch fastener so that upper side frame covers closely.
Compared with prior art, the present invention is advantageous in that：By setting reinforcer in push handle, make push handle intensity
Greatly improve, rather than rely solely on the intensity of push handle plastic rubber material itself, so as to which push handle is not easy to break during stirring, stir
Process is relatively reliable.
