CONTACT SPRING AND SUPPORT STRUCTURE FOR DIGITAL MULTIMETER

摘要

The present invention relates to a contact spring mounted in a rotary switch of a digital multimeter.;According to the present invention, a contact spring having a pair of contact portions formed by cutting and forming a central portion and both ends extending outwardly is supported on both sides of the support surface of the support portion inside the handle, and the internal contact is caused by the rotation of the handle. In the digital multimeter in contact with the pattern, the support surface on which both ends of the contact spring are supported is protruded in a round shape so that the contact spring is rotatably supported in a circumferential direction.;And as another embodiment, instead of making the support surface protrude round, by forming both ends of the contact spring in a round shape, the contact spring is rotatably supported in a circumferential direction on the support surface inside the handle.
