Abstract: 本发明提供一种按键模块及其键盘，按键模块包括一底座、一剪刀型元件及一键帽。剪刀型元件设置于底座且连接于底座，键帽置于剪刀型元件且连接于剪刀型元件。剪刀型元件的第一框架的一连接轴转动地连接于第二框架的一轴孔，且轴孔与连接轴之间具有一行程距离供该连接轴沿一预定方向位移。底座具有一限制单元，键帽设有一枢接单元；借由第一框架及第二框架的第一侧分别可转动地枢接于枢接单元、以及第二侧分别可滑动地设置于限制单元，以及连接轴于轴孔内位移，使第一框架相对第二框架间转动，进而使键帽可相对底座作上下升降运动。

Abstract: 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.

Abstract: 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.

Abstract: 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.
