| An automatic electric load transfer switch incorporates an over-the-center spring mechanism to operate switch contacts. The spring mechanism has a first position at which the electric load is connected to one electricity source and a second position at which the load is connected to another electricity source. The spring mechanism is driven by a solenoid activated cam shaft. An apparatus is provided for halting the movement of the spring mechanism at a position intermediate the first and second positions at which the load is not connected to either electricity source. The halting apparatus is releasable so that the spring mechanism can continue its movement between the first and second positions. | ||||||
| 3 | Keyboard switch assembly with improved movable contact | US3742157D | 1971-04-16 | US3742157A | 1973-06-26 | LEPOSAVIC W |
| A multiple switch construction for a keyboard or the like produced as a flat panel embodying laminates of electrical conductors in desired patterns, assembled as stratifications in close proximity and separated by spacers. Individual depressible means operating through resilient members urge movable switch elements into contact with fixed electrical conductors with a rotary, wiping action to insure positive electrical contact.

| 4 | Multiple switch construction | US3600528D | 1969-09-25 | US3600528A | 1971-08-17 | LEPOSAVIC WAYNE V |
| Multiple switches produced as a flat panel embodying the basic principle of laminates of electrical conductors in desired patterns assembled as stratifications in close proximity but separated by spacers and covered by resilient material facilitating momentary pushbutton operation of companion switch elements thereof, the separators isolating companion switch elements of the stratified laminates within switching zones identified by indicia or pushbutton pads on the resilient cover.

| 5 | Switch | JP32032388 | 1988-12-19 | JPH0215529A | 1990-01-19 | JIEEMUZU EE BETSUKAA; ROORENSU EFU FURAITAGU; FURANKU DABURIYU KUSHII |
| PURPOSE: To easily switch to an emergency power supply by stopping the movement in the position where a load is not connected to one power supply of two power supplies when an over-center type spring mechanism is moving. CONSTITUTION: In order to alternately connect an electric load 91 to one power supply of two power supplies 94, 96, an over-center type spring mechanism 48 is operated by linking with connecting devices 24, 90, and driving devices 30, 34, 40 are driven so as to pass the central position from first and second positions. When the over-center type spring is moved between the first position and the second position, devices 17, 81 stop the movement in the position where a load is not connected to one power supply. Like this, an off-center position is formed. Thereby, the load can be connected to either power supply. COPYRIGHT: (C)1990,JPO | ||||||
