A fixed terminal having a fixed contact and an L-shaped moving member terminal are mounted through oblong openings of a bottom plate of a switch case at each one end. A moving switch-plate having a moving contact at one end part is suspended on the other end part of the L-shaped moving member terminal with a change-over member and a U-shaped leaf spring so that the longitudinal direction of the moving switch-plate is substantially parallel to the bottom plate of the switch case, and that the other end of the moving switch-plate is moved by a slide member to operate the switch.

Switch

A casing 1 has an inside bottom and an open top. Fixed terminals 2 and 3, having stationary contacts 2a and 3a, are provided on the inside bottom of casing 1. An operational lever 5 is swingably supported at the upper part of casing 1. A contact piece 4, made of a resilient thin plate formed into a U-shaped configuration, has a base end engageable with the pivot portion of operational lever 5 and a movable portion 4f brought into contact with the lower surface of operational lever 5. The distal end of contact piece 4 is provided with movable contacts 4b and 4c which are slidably brought into contact with stationary contacts 2a and 3a.

Lever operated slide switch

A stationary terminal 12 and a common terminal 13 are provided on a bottom of an insulating case 11. A pivot 14a is provided on an upper end of common terminal 13. A change-over plate 14 is rotatable about and brought into contact with the pivot 14a. A projection 16a, provided under slider 16, is brought into contact with and slidable along a sliding surface 14g of change-over plate 14 at a position lower than the pivot 14a. Change-over plate 14 causes a seesaw movement about the pivot 14a, and quickly accomplishes the switching movement regardless of the shifting speed of slider 16. Thus, it becomes possible to provide a switch which is highly reliable and free from burnout and welding of the contacts.

Switch for use in electronic devices

A remote controlled electrical circuit apparatus having a master control device, a slave electrical circuit device capable of providing variable electrical circuit parameters in response to a force applied thereto, a force-transmitting mechanism including a transmitting thin strip member, longitudinally spaced transverse sections overlying different sides of the transmitting member and a pair of thin strip guide members rigidly connected to the transverse sections. The transmitting and guide members both have the same thickness and are disposed on the same plane to permit them to have a same radius of curvature when subject to bending. A connector at each end of the force-transmitting mechanism connects a respective end of the mechanism to one of the master and slave devices.
