| Number | Title | Issue Date |
| 7186940 | Electrical switch An electrical switch includes two fixed contacts and a moving contact supported for movement between an ON position in contact with the fixed contacts and an OFF position out of contact with the fixed contacts, and an operating mechanism for moving the moving contac... | 03/06/2007 |
| 7115829 | Switch A switch includes a contact mechanism having at least one contact and defining a longitudinal axis. Actuation of a handle moves the contact mechanism transversely to the longitudinal axis between an open position and a closed position in relation to at least one fix... | 10/03/2006 |
| 7112751 | Switch mechanism for reversible grinder A switch mechanism for use with reversible handheld power tools comprises a pair of switches that co-operate using abutment to restrict displacement of each switch according to the position of the other switch. In a tool having a dynamic brake and a series-wound mot... | 09/26/2006 |
| 7105762 | Rocker switch and actuator therefor An actuator assembly is for a short-depth rocker switch including a housing having an opening, a cavity, a base, and a first depth between the opening and base. The actuator assembly includes an operating member having a first end disposed proximate the opening, and... | 09/12/2006 |
| 6919523 | Electrical switch An electrical switch includes a casing having a central and two side chambers that are separated from the central chamber by respective partitions. A switching mechanism in each second chamber has fixed and moving contacts and an actuator. A rocker in the central ch... | 07/19/2005 |
| 6664490 | Switching mechanism and electric switch using the same An AC/DC switch for electric power tools avoids bouncing when turned on, but assures quick cutting-off of heavy current. Operation does not vary with age, as might be caused by wearing of projections of the switching mechanism and/or inconsistency in spri... | 12/16/2003 |
| 6080949 | Quick-break switch with a reinforced pressure point A quick-break switch in which, for switching-over purposes under the spring force (1) of a switching element, the two individual wedge faces of a wedge surface are felt. In order to render the pressure point more perceptible, in particular when the switch... | 06/27/2000 |
| 5821481 | Quick-make-quick-break microswitch with wedge profile at the contact arm pivot-mounted in the switch A snap switch having spring a spring energy store and wedge profile. In conventional switches, the wedge profile was attached to the end of the contact arm, which forms the moving switching element. Heating of the contact arm due to large, switched electr... | 10/13/1998 |
| 5532444 | Push button switch A push button switch, particularly a power supply switch, has contacts (4, 5) attached to a housing and a movable contact bridge (8) which is moved by means of a spring plunger (10'). A spring switching mechanism (26) transmits force between the spring pl... | 07/02/1996 |
| 5426274 | Push button switch A push button switch, particularly a master switch, has housing-affixed contacts (4, 7) and at least one contact bridge (8, 9) movable by a spring plunger (10). A spring-switching mechanism (24, 25, 26) is operatively coupled between the spring plunger an... | 06/20/1995 |
| 5360954 | Push button switch A push button switch, particularly a master switch, has housing-affixed contacts (4, 5) and a contact bridge (8) for bridging the contacts, with the bridge being moved by a spring plunger (10). A spring-switching mechanism (24, 25, 26) is operatively coup... | 11/01/1994 |
| 4788388 | Snap acting switches A snap acting switch comprising an elongate cantilever mounted spring member having a contact portion, an electrically conductive element upon which the contact portion bears, and an actuator having surfaces intersecting at an angle, one of the surfaces b... | 11/29/1988 |
| 4477703 | Tripping device for thermal relays A device for tripping thermal relays includes a tilting fork controlled by a pusher which acts on a tension spring which connects a mid point of the fork to a fixed point of the casing of the device. The fork at its free movable end is joined to a contact... | 10/16/1984 |
| 4169974 | Push operated momentary switch A momentary push button switch having a helical spring contact with tangentially extending opposite ends. The spring is seated over a vertical post on a base member and the lower tangential end of the spring permanently engages one stationary contact in t... | 10/02/1979 |
| 3994483 | Spring for maintaining in place an electric component and for ensuring its electric contact A spring having three juxtaposed elastic blades connected to each other only at each end by two transversal portions. The central blade is cambered in a first direction and the two lateral or outside blades are cambered in an opposite second direction. Th... | 11/30/1976 |
