Abstract: A flashlight including a light source, a power source, at least one push button electrically coupled to the light source and power source, and a rotatable switch assembly comprising a wheel, a cam fixed to the wheel, and a spring, wherein rotation of the wheel to different positions causes the cam to interact with the spring such that the at least one push button is selectively depressed, resulting in adjustment of the light source between different states of operation.
Abstract: The disclosure relates to a cam disc and to a spring deflection switch having a cam disc for a spring-loaded drive, wherein the cam disc includes a first, second and third circumferential region, each having at least one corresponding radial extension, for actuating a pushbutton including a switching hysteresis. The at least one second radial extension is larger than the at least one third radial extension, which in turn is larger than the at least one first radial extension. The pushbutton can interact with the cam disc in the spring deflection switch such that when the pushbutton is applied by the first circumferential region, the switching contact assumes a first switching position, and when the pushbutton is applied by the second circumferential region, the switching contact assumes a second switching position, and when the pushbutton is applied by the third circumferential region, the switching contact remains in the switching position assumed earlier.
Abstract: A double pole, double throw rocking contactor switch is operable as a reversing switch by particularly configured stationary contacts at the corresponding ends of the respective poles. Stationary contacts are formed electrically common out of a single member having the stationary contact of one pole formed to be disposed below the rocking contactor and the stationary contact of the other pole formed to be disposed above its respective contactor. Accordingly, one contactor engages the upper surface of a stationary contact while the other end of the other contactor engages the under surface of the opposite stationary contact for a given stable position of the actuator, thereby causing the respective contactors to engage stationary contacts at respective opposite ends of the contactors, accomplishing the reversing function internally of the switch without special cross connect conductors, thereby permitting press-in wire terminations to be utilized.
Abstract: The pushpiece mechanism for a timepiece comprises pushpiece return means arranged so that the force applied to the pushpiece passes through a maximum at an intermediate position thereof between a rest position and the pushed-in position of the pushpiece.To this end the return means are provided with two bearing elements arranged to cooperate with one another and comprising respectively a beak and a heel coupled by an elastic member, such bearing elements and elastic member being formed as a single piece.The mechanism may be applied in particular to electronic timepieces including a chronograph function.
Abstract: Improved blade-type, air dielectric switchgear apparatus is provided having spring loaded, fast acting, operator independent mechanism for selective opening and closing of internal switch contacts. Preferably, the operating mechanism includes a pair of opposed, pivotal, notched, scissor-like arms with a rotatable latch plate therebetween; a pair of latching pins are carried by the plate, and the latter is operably connected with a power spring assembly. A trip element is also provided which, upon rotation thereof in either a clockwise or counterclockwise direction, serves to shift a corresponding arm away from the latch plate to disengage the latching components. At this point a high velocity rotational movement is imparted to the latch plate by the spring assembly to rotate the latch plate to a second position wherein the plate and the opposed arm come into latching engagement.
