Abstract: A micro switch for detecting forces in two orthogonal directions, rather than one, useable, for example, to detect out of size parts in one plane in a multiple spindle screw machine, and disengaged parts in an orthogonal plane. This is accomplished through the provision of a ramp that is slidably engaged by the switch's actuation rod as the rod moves in a first plane to translate sideway movement of the rod into perpendicular linear movement of the switch's plunger. The ramp has a recess that captures the rod as it moves in the orthogonal plane, which is coincident with the axis of the plunger, thereby causing switch actuation with plunger movement in two planes.

Momentary contact is provided at an intermediate location between extreme positions of the actuating lever of the existing switch or other moveable structure. Additional contacts can be provided to alter switch function and/or allow discrimination of direction of movement at an intermediate location. The switch can be retrofit to any existing structure without modification of that structure or disturbance of wiring to which that structure is connected.

Abstract: A handle actuator is provided for a circuit interrupter that has a handle or toggle pivotally movable between operative positions. The handle actuator has a pair of pins that fit tightly on the handle, a pair of retainers coupling the pins in a rigidly spaced parallel relationship, and a pair of flanges fixed to the circuit interrupter via a base. The flanges are disposed on opposite sides of the handle and have arcuate slots that guide the pins coaxially with the pivot axis of the handle. The ends of the pins extend through the arcuate openings of the flanges and are received in the retainers. Connecting links pivotally couple the pins with a drive input for selectively driving the pins against the handle to move the handle between the operative positions. The relative position of the pins on both sides of the handle is constant, preventing wear on the handle due to rolling of the pins against the handle, impacts with the handle permitted by lost motion, or bending and twisting forces.

The wall plate member and sliding member are extended downward from an existing switch apparatus allowing a child or disabled person to operate the light switch from a height beneath the switch. Full use of the light switch is retained by the present invention for utilization in standard manner by means of an enlarged aperture in the wall plate member receiving the light switch lever. The wall plate member and sliding member are easily installable on a permanent, as well as temporary, basis.

Abstract: The invention provides a clamping device which removably secures a body to a cable, the clamping device comprising a toothed, tapered cable gripping insert which fits into a stepped, tapered recess slot in the body. The cable gripping insert is retained in position by a T-shaped latching bar on the top of the insert which fits into transverse grooves in the body on either side of the recess slot. A clamped cable exits the recess slot at right angles to its entry, providing pivoting action. The cable attaching device is particularly suited for use with an attachment for use with a float switch assembly. Such an attachment may be used as a weighted pivot for a float switch or alternatively as an unweighted float for extending the range of an existing float switch assembly.

Abstract: Disclosed is a double button device on a VCR comprising a front panel where a double button being set, a cover door being hinged at an inner front panel and opened selectively whenever necessary, an outer button set outward on a cover door, a tact switch for sending an electrical signal to a printed circuit board by an inner or an outer button being pressed, an inner button set on an inner front panel to connect a tact switch with an outer button of frequent use, and a mode switch for changing the mode of a tact switch when a cover door is opened or closed.

Abstract: An electrical trigger switch for controlling current through a pair of main leads. The switch includes a guard, which physically protects the trigger button from being depressed accidentally, and also an electrical safety feature. Particularly in harsh environments, the mechanical protection afforded by the guard alone may be insufficient. The trigger button may be depressed unintentionally, causing accidental injury. Accordingly, the guard of the present invention includes an electrical safety switch. The safety switch moves from a safety state to an enable state only when the guard is pivoted upward to an armed position. Unless the guard is so pivoted and the safety switch is placed in an enable state, the safety switch will stay in a safety state, disabling the trigger button, even if the trigger button is depressed.

Abstract: A mechanism is provided for throwing several toggle switches together, especially toggle contact breakers, which are enclosed in an explosion proof container. A link between the toggles distributes manual toggling force over all of them from a single manual throw switch. The single manual throw switch may be located outside the explosion proof container and be connected to the link to the toggles through a wall, e.g., a moveable wall such as a door. In one practical embodiment, the link is an elongate tie bar for the toggles, and the manual throw switch is connected to the spaced apart forks which are geared together.
