By adopting technique scheme, consequently: can increase two creepage distances between pin, still can use safely in the situation that electric current is larger, increase the dependability of described sensitive switch.
Of the present utility modelly further be set to: described drive rod is divided into three parts, be respectively from down to up stop portion, support section, pressing part, stop portion is an inclined-plane of conflicting and coordinating with housing, on support section, be provided with housing on the projection that is rotatably assorted of fulcrum, pressing part is drive rod free end.
By adopting technique scheme, consequently: on drive rod and housing, fulcrum forms a set of lever system, stop portion can only be rotated in the part limiting drive rod, can realize with very light dynamics the keying of switch change by pressing part.
Of the present utility modelly further be set to: one end that described common pin inserts in housing is provided with the first rivet installing hole, quick-action conductive reed stiff end is provided with the second rivet installing hole matching, the first rivet installing hole and the second rivet installing hole coaxial cooperation, rivet runs through the first rivet installing hole and the second rivet installing hole, the fixing riveted joint of common pin and quick-action conductive reed.
By adopting technique scheme, consequently: make the connection between quick-action conductive reed and pin more firm, effectively extended the useful life of switch.
Of the present utility modelly further be set to: the stressed rear in described pin upper contact position and riveted position is provided with support bar.
By adopting technique scheme, consequently: in the swing process of the process of pressing and quick-action contact, stressed member can not depart from the position of setting, has effectively extended the useful life of switch.
In addition, on existing structure, switch is amplified and strengthens design, the switch obtaining can be applied on main equipment at the safe end.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
