Cover each member assembled on top of 7. Magnetic pole plate 2a
and 2b are fixed to the contact spring driver 4 with the permanent magnet 3 sandwiched therebetween. The two L-shaped contact spring drive body holding parts 9 have locking hooks formed on the flange part 11 forming the end face of the coil assembly 7, and are located inside the upper block of the contact spring drive body 4 as shown in the drawing. The hidden shaft portion 12 (see FIG. 1) is loosely fitted in a bar-like manner. The contact spring driver 4 moves in the direction of arrow A as shown in FIG. 2, and the shaft portion 12 slides on the contact spring driver holder 9. Shaft part 12
is a linear protrusion 121 parallel to the sliding direction on the sliding surface.
(see Figure 1), the sliding surface is minimized to reduce sliding resistance.

押圧、開放して接点を切替る。 The movement of the contact spring driver 4 in the direction of arrow A occurs when the excitation winding 71 of the coil assembly 7 is energized and the magnetic circuit is closed by the iron core 5 and the yoke 6. This is realized, for example, when one magnetic pole plate 2a that has been in contact with the other magnetic pole plates 2a is released and the other magnetic pole plate 2b is brought into contact with the other magnetic pole plate 2b. Through this operation, the contact spring driver 4 presses and releases the contact spring 22 provided on the base 17 to switch the contact.
