These can reliably prevent the tilting of the operating member.
  • the shape of the movable contact 8 is formed bilaterally symmetrically. Therefore, attachment of the movable contact 8 to the operating member 7 becomes easy. Further, since the holding portion 7b of the operating member 7 has the pair of walls 7b3 which can be provided to face each other to shield the movable contact 8, attachment of the operating member 7 which holds the movable contact 8 to the upper case 1 becomes easy. These can improve assemblability.
  • the pair of walls 7b3 cover the first and second elastic arms 8a and 8b including the first and second contact portions 8a1 and 8b1, the first and second elastic arm 8a and 8b are protected by the pair of walls 7b3 during attachment. This prevents deformation.
  • the pair of walls 7b3 cover the whole movable contact 8
  • the tilting of the movable contact 8 can be suppressed via the pair of recesses 1d as a pair of guide portions provided in the upper case 1.
  • the supporting portion of the lever 3 is arranged at one end of the upper case 1, and as shown in Fig. 2 , etc., the operating member 7 is arranged at the other end of the upper case 1.
  • a dead space inside the upper case 1 to be formed between the one end of the upper case 1 and the coil spring 9 can be effectively utilized as routing regions of the terminals 4a and 5a of the first contact 4 and the second contact 5 which forms fixed contacts.
  • the insulating portion 11 provided between the first contact 4 and the second contact 5 is made of insulating resin, and the insulating portion 11, the first contact 4, and the second contact 5 are arranged such that the surface of the insulating portion 11 and the surfaces of the first contact 4 and the second contact 5 are included in the same plane.
  • the second contact portions 8b1 of the movable contact 8 can be made to slide smoothly and excellent ON and OFF performance can be secured, in a state where contact pressure is kept constant among the surface of the first contact 4 which forms a fixed contact, the surface of the insulating portion 11, and the surface of the second contact 5 which forms a fixed contact during sliding of the movable contact 8 accompanying the movement of the operating member 7 by the pressing operation of the lever 3.
  • the surfaces of the insulating portion 11 are provided with the groove 11a.
  • the metal powder or resin power generated by the sliding between the second contact portions 8b1 of the movable contact 8, and the first contact 4 and the second contact 5 which form fixed contacts, or by the sliding between the second contact portions 8b1 of the movable contact 8 and the insulating portion 11 made of insulating resin can be accommodated in the grooves 11a of the insulating portion 11 with the sliding of the movable contact 8.
  • a switching contact portion is constituted by the first contact 4 and the second contact 5 which are arranged vertically so as to sandwich the insulating portion 11.
  • the first contact 4 may be excluded from the above-mentioned configuration, and places other than the first contact 4 may be formed in an insulating portion connected to the insulating portion 11.
  • the second contact portions 8b1 of the movable contact 8 contacts the insulating portion connected to the insulating portion 11.
  • the common contact 6 and the second contact 5 are cut off from each other, resulting in an OFF state.
  • the common contact 6 may be a fixed contact of a switching contact portion adapted to have the same shape as the second contact 5 in which an insulating portion is formed as mentioned above.
  • the first and second contact portions 8a1 and 8b1 of the movable contact 8 contact the insulating portions, respectively, resulting in an ON state.
  • the first and second contact portions 8a1 of the movable contact 8 and 8b1 contact the fixed contacts by the pressing operation of the lever 3, this results in an ON state. Even in such a configuration, switching of ON and OFF according to the pressing operation of the lever 3 can be performed.
  • the above-mentioned embodiment is configured such that the first contact 4 and the second contact 5 which constitute a switching contact portion, and the common contact 6 are provided uprightly from the case base 2 as a pair of fixed contacts in the upper case 1.
  • the invention is not limited thereto.
  • one fixed contact of a pair of fixed contacts may be erected from a bottom wall of the case base 2, the other fixed contact may be erected from a side wall on the side of one end of the upper case 1.
  • the positions where the fixed contacts are erected may be suitably changed.
  • the other pair of fixed contacts which have different heights other than a pair of fixed contacts may be provided in positions lower than the pair of fixed contacts, and the other pair of elastic arms may be provided in the movable contact 8 in correspondence to the other pair of fixed contacts. Even in such a configuration, contact portions formed in two pairs of elastic arms of the movable contact 8 are gradually brought into contact with corresponding fixed contacts by the pressing operation of the lever 3, so that an ON and OFF state can be obtained gradually.
  • the fixed contacts and the elastic arms are not limited to one pair, and the number thereof to make pairs may be suitably set according to designs.
  • the movable contact may not be formed bilaterally symmetrically.
  • one elastic arm provided with contact portions which sandwich a common contact may be provided on one side of the movable contact, and a plurality of elastic arms provided with a plurality of contact portions which sandwich a normal open contact and a normal close contact may be provided on the other side of the movable contact.
  • the grooves 11a which can accommodate metal powder or resin powder are formed in the central portion of the insulating portion 11.
  • the invention is not limited to a configuration in which the grooves 11a are arranged in the central portion of the insulating portion 11.
  • the groove 11a may be provided at the end of the insulating portion 11 which be located in a boundary between the first contact 4 and the insulating portion 11, and may be provided at the end of the insulating portion 11 which is located in a boundary between the second contact 5 and the insulating portion 11.
  • the grooves may not be provided.
