[embodiment]

Please refer to Fig. 1 to shown in Figure 4, the utility model actuating type switch 1 comprises insulating body 10, plurality of fixed terminal 20, movable terminal 30, actuator 40, back-up block 50 and lid 60.

Insulating body 10 roughly is the box-shaped of top opening, comprises that diapire 11 reaches antetheca 12, rear wall 13, the two side 14 that extends upward setting around diapire 11.Wherein diapire 11 is concaved with a roughly rounded accepting groove 15 downwards, rear wall 13 middle parts are provided with first breach 16, then be arranged with second breach 17 on the two side 14, in addition, antetheca 12 and rear wall 13 at 14 places, contiguous two side respectively symmetry convex with projection 18.

Plurality of fixed terminal 20 is arranged in insulating body 10 diapires 11, comprises the first terminal 21 and second terminal 24, and the first terminal 21 comprises that first contact site 22 and first weld part, 23, the second terminals 24 comprise second contact site 25 and second weld part 26.First,

second contact site

22,25 bottom of protruding the accepting groove 15 on insulating bodies 10 wherein, and first,

second weld part

23,26 protrudes out insulating body 10 both sides in order to weld mutually with electronic device circuit plate (not shown).In the present embodiment, fixed terminal 20 is to be integrally formed in the insulating body 10.

Movable terminal 30 is provided with the top that is circular arc 31 that raises up and is located at top 31 sidepiece 32 all around.Actuator 40 is provided with movable part 41 and is convexly equipped with out insulating body 10 press section 42 outward.Wherein movable part 41 then is provided with Actuator Division 44 in the middle of being provided with 43, two support portions 43, two support portions, and Actuator Division 44 front ends are provided with first inclined-plane 45.
