摘要： A latching relay has a fixed iron core including an exciting coil wound around an intermediate portion and a magnetic pole piece at two ends; movable iron pieces sandwiching a permanent magnet between two bar-shaped iron pieces disposed in parallel with each other, and are fixed with a holder; and a switchable electrical contact portion. The fixed iron core and the movable iron pieces are disposed facing each other to insert each of the magnetic pole pieces on two sides of the fixed iron core to be spaced apart in a space between the two bar-shaped iron pieces of two end portions of the movable iron pieces. The movable iron pieces are supported pivotally in a direction in which the two bar-shaped iron pieces are aligned. The movable iron pieces are linked to the electrical contact portion, and the movable iron pieces perform a switching of the electrical contact portion.

摘要： An operation portion and a switch portion of a push button switch are removably coupled. The switch portion includes a contact opening mechanism having a rotatably supported lever and a spring. The lever has one end acting on a part of the operation portion coupled with the switch portion, and the other end acting on a contact switching mechanism of the switching contact unit in the switch portion to open/close the contacts. The spring urges the lever in a fixed rotation direction. The contact switching mechanism is urged to move a movable contact from a standby state position toward an operating state position by the contact opening mechanism when the switch portion is separated from the operation portion. The contact switching mechanism is released from the urging when the switch portion is coupled with the operation portion.

摘要： An electromagnetic contactor includes an iron core members formed of a first core bent in a U-shape, and a second L-shaped core contacting the first core. A coil is wound around a spool disposed on an upper arm of the first core and the second core to form a main leg while a lower arm of the first core constitutes a yoke. Thus, the iron core members can be processed by a press machine operating at a normal cutting speed, and welding and polishing operations can be eliminated to thereby reduce the number of processing steps required.
