| In this breaker device, a pair of stationary electrodes 35, 35 are arranged while the protruding wall 32 is interposed between them and the U-shaped movable electrode 60 is engaged with them so as to close an electric circuit. The protective protruding section 61 is arranged at an upper end of the stationary electrode 35, and the protrusions 62 are provided on both sides of the protective protruding section 61. When the movable electrode 60 is engaged, it is elastically expanded and deformed when it comes into contact with the protrusion 62. Even in a case in which the protrusion 62 is scraped away by the friction caused between the protrusion 62 and the movable electrode 60, since the protrusion 62 is located at a position shifted from the stationary electrode 35, the scraped powder never gets into between the movable electrode 60 and the stationary electrode 35. | ||||||

| 160 | Detented paddle blade switch assembly | US326886 | 1994-10-21 | US5486669A | 1996-01-23 | Thomas J. Oshgan |
| A lever type switching assembly having a pair of generally U-shaped spring blade contact members disposed in oppositely spaced-parallel arrangement for alternate actuation by a common paddle lever frictionally contacting the contact members for effecting switching upon user movement of the lever in a clockwise direction. Each contact blade member has one end pivoted on a center contact for rocking motion to cause the U-shaped region and the opposite end of the blade member to make and break contact with side-contacts on opposite sides of the center contact. Overtravel of the paddle in one direction after actuation causes the contact blade member to break from the side contact and make contact with an auxiliary contact. A spring biased plunger on the paddle lever engages a detent surface on the base to give a tactiley discernible indication. | ||||||
