    • An electrical receptacle is disclosed which deactivates the front of an electrical receptacle when an electrical plug is not present. The receptacle includes a semiconductor switch mounted between the hot contacts of the receptacle, and the hot conductor of an electrical power cable. The receptacle also includes a momentary contact switch located between the contacts of the ground receptacle portion, activated by the ground pin of an electrical plug upon engagement, and deactivated upon retraction of the electrical plug. The momentary contact switch, when activated, also activates the semiconductor switch which in turn, activates the receptacle front. A second embodiment of the invention further includes an optoelectronic switch in series between the momentary contact switch and the semiconductor switch which requires redundant activation of both switches for activation of the receptacle front, remotely activating the optoelectronic switch and local activation of the momentary contact switch by the electric plug.

    • Electrical connector for telephone wiring interface providing lightning protection is formed by dielectric base having first terminals thereon for terminating wires and having upright first members aligned with apertures in a dielectric cover latched to base and a stanchion normal received in a dielectric jack mounted to the base to provide testing by inserting a plug inserted through an aperture in the cover. A plug member has second terminals fixed thereon for receiving wires and upright second mating members arranged to mate with first mating members in apertures. Base and cover accommodate a lightning arrester and include a removable insert to compensate for arresters of different sizes.

    • Electrical connector for telephone wiring interface comprises dielectric base having four stamped and formed first terminals thereon which receive screws for terminating wires and have upright first mating members aligned with apertures in a dielectric cover latched to base. Each first terminal is formed with a stanchion normal to the base and a spring contact which are received in a dielectric jack mounted to the base to provide testing by inserting a plug inserted through an aperture in the cover. A plug member has four stamped and formed second terminals fixed thereon which receive screws for terminating wires and upright second mating members arranged to mate with first mating members in apertures. Plug member has a leg flanking each second mating member, the legs being profiled to fit closely in apertures to align respective mating members for mating, which retains plug member against cover. Base and cover accommodate lightning arrestor and circuitry as desired.
    • 用于电话线路接口的电连接器包括介电基座,其上具有四个冲压和形成的第一端子,其上接收用于端接线的螺钉,并且具有与锁定到基座的电介质盖中的孔对准的直立的第一配合构件。 每个第一端子形成有垂直于基座的支柱和弹簧接触件,该弹簧接触件容纳在安装到基座的介电插座中,以通过插入通过盖中的孔插入的插头来提供测试。 插头构件具有固定在其上的四个冲压成形的第二端子,其接收用于端接线的螺钉和布置成与孔中的第一配合构件配合的直立第二配合构件。 插塞构件具有位于每个第二配合构件侧面的腿部,腿部被成型为紧密地配合在孔中以对准用于配合的相应配合构件,其将插塞构件保持抵靠盖。 基座和盖子根据需要安装避雷器和电路。

    • Joystick switch comprises a handle attached to a support member carrying a ball member which rides in a socket fixed on a base. A straight length of resilient wire fixed to the base passes through an aperture defined by four discrete contacts in the base and into a bore in the ball member where it is slideably received. Arcuate movement of the handle causes lateral deflection of the wire into contact with the contacts to generate signals for x-y directional control. Die cast zinc circuitry in the base provides grounding for the wire and signal current for the contacts. Resilient return action for the handle is effected by an elastomeric ring in the base which bears on an annular surface of the support member.
    • 操纵杆开关包括一个手柄,该把手附着在一个承载着固定在基座上的插座中的一个球形件的支撑件上。 固定到基座上的直线长度的弹性线穿过由基座中的四个分立触点限定的孔,并且穿过球体中的可滑动接收的孔。 手柄的弓形运动导致电线的横向偏转与触点接触以产生用于x-y方向控制的信号。 基座中的压铸锌电路为触点提供接地线和信号电流。 用于手柄的弹性回复作用由支撑在支撑构件的环形表面上的基座中的弹性体环实现。
