Description

[Detailed Description of the Invention] Technical Field The present invention fixes at least a pair of strip-shaped leaf members to an insulating base, at least one of the leaf members has elasticity, and utilizes the elasticity to make one of the leaf members The present invention relates to a leaf switch comprising an operating tip member having a convex surface and convex surfaces on both sides of the tip for bringing the leaf member into contact with and separating from another leaf member, and particularly relates to improvements in the operating tip member.

BACKGROUND TECHNOLOGY As shown in Fig. 1, the conventional leaf switch
A strip-shaped leaf member 11 made of a pair of spring materials,
12 has one end portions 14 and 15 fixed to an insulating base 13, and the other end portions 16 and 17 extending substantially in parallel. The other ends 16 and 17 protrude longer than the one ends 14 and 15. Attachment holes 18 and 19 for connecting lead wires are bored in one end portions 14 and 15. A contact 20 is protruded from one or both of the inner surfaces of the other ends 16 and 17. and the other end 16,1
An operating tip member (separator) 23 having concave surfaces 21 and 22 inclined in the longitudinal direction of the leaf members 11 and 12 on both sides and a convex surface 27 in the middle thereof is fixed to the outer surface of the leaf member 7. The base body 13 has mounting holes 2
It has 4.

This leaf switch 10 has a base 13 mounted at a desired position, lead wires connected to mounting holes 18 and 19, and a convex surface 2 near the operating chip member 23.
7. An operating rod 26 movable in the direction of the arrow 25 or in the opposite direction is installed so as to abut against the concave surfaces 21 and 22. The operating rod 26 is connected to, for example, a push button, and is moved in the direction of the arrow 25 or in the opposite direction depending on the operation of the push button. When the operating rod 26 is moved in the direction of the arrow 25,
It abuts against the concave surface 22, reaches the convex surface 27, and abuts against the concave surface 21. When the operating rod 26 collides with the convex surface 27,
The other end 16 of the leaf member 11 is pressed and bent by the other end 17 of the leaf member 12 against the elasticity of the leaf member 11, and both ends 16 and 17 are brought into contact via the contact 20 and closed. Ru. Further, when the operating rod 26 reaches or leaves the concave surface 22 or 21 of the operating tip member 23, both ends 16 and 17 are brought into a non-contact state and are opened.

However, according to such a conventional device, the operating tip member 23 has one convex surface 27 and concave surfaces 21 and 22 on both sides, so that the contact point 2
If it is necessary to repeatedly connect and release (on and off) 0 several times in succession, the operating rod 26 must also be moved back and forth repeatedly, which has the drawback of complicating the structure and control of the operating rod 26 and making it expensive. Ta. Also, operating rod 26
The mounting position for the operating chip member 23 was also limited to one location.

DISCLOSURE OF THE INVENTION The present invention was proposed in view of the above points, and by moving the operating rod 26 to one side, it is possible to repeatedly turn on and off multiple times during that time, and the mounting position of the operating rod 26 can be changed to a certain extent. The purpose is to provide a variable leaf switch.

For this purpose, the present invention has a structure in which the operating tip member of the leaf switch is formed with a plurality of consecutive sets of convex surfaces and concave surfaces on both sides thereof.

Therefore, according to the present invention, by moving the operating rod in one direction with respect to the operating tip member, a plurality of leaf switches are turned on and off in succession. Further, the mounting position of the operating rod relative to the operating tip member can be selected within the range of the uneven surface of the operating tip member.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 2 is a perspective view showing an embodiment of the invention, and the same parts as in FIG.
What is new in FIG. 2 is that the operation tip member 23 has convex surfaces 27a, 27b, 27c and concave surfaces 22a, 21a, 22b, 21b, 22c, 21 on both sides thereof.
c, it has three times as many uneven surfaces.

According to this, when the operating rod 26a is moved in the direction of the arrow 25, the operating rod 26a moves to the convex surfaces 27a, 27.
Each time it collides with b and 27c, the contact point 20 contacts,
turned on. Also, concave surfaces 22a, 21a, 22b, 2
1b, 22c, and 21c, the contact 20 is separated and turned off.

Therefore, according to the present invention, the leaf switch 10 can be turned on or off by moving the operating rod 26a relative to the operating tip member 23 in the direction of the arrow 25 or in the opposite direction.
The switch can be turned off three times in a row, and can be switched on and off in multiple stages.

Further, the operating rod 26a can be mounted at a position as shown in 26b, and the mounting position can be changed.

The present proposal is not limited to the above-mentioned embodiments,
Various design changes are possible. For example, in the leaf switch of the embodiment, the leaf members 11 and 12 are always separated and in the OFF state, but this can also be applied to a leaf switch in which the leaf members 11 and 12 are always in contact and in the ON state. In this case, the operating lever 26a and the convex surfaces 27a, 27b, and 27c collide with each other to turn the device into the OFF state.
