A miniature ratchet type push button activated electrical switch having a mainspring and an auxiliary spring wherein spring rates, spring lengths and spring orientations are selected such that a substantial depression of the push button is required before electrical continuity is broken in a closed circuit. This configuration additionally serves to reduce the amount of audible noise generated by the switch during the ratcheting operation.

Pre-loaded switching apparatus and method of operation

Terminals for electrically contacting wire loops disposed on each end of a cartridge type bulb are formed from resilient electrically conducting sheet metal. Each terminal consists of an elongated member having a relatively narrow contact portion joined to a wider base portion at a shoulder. The contact portion has a outwardly projection tab acting to retain the wire loop of a cartridge type bulb, while the base portion has a downwardly projecting tab for securing the terminal in a lamp housing or socket assembly. A means for electrically connecting a wire to end of the base of the terminal is provided by arcuate shaped projecting tabs which can be crimped over the wire core and insulating jacket.

Connection terminals for rigid-wire loop cartridge light bulbs

A miniature ratchet type electrical switch exhibiting a reduced audible noise level operation having a damping spring incorporated in a ratchet mechanism switch construction for reducing the forces otherwise exerted on the ratcheting mechanism by a main spring during the camming and seating operation of the components with the force exerted by the damping spring opposing the force exerted by the main spring, thereby reducing the noise associated with this function, and including a reprofiled tooth and cam configuration for preventing the jamming of the moving parts. Incorporation of these features in a ratchet mechanism type electrical switch in which the main spring completes the switch circuitry yields a reliable and aesthetically improved switch function with a high current carrying capacity. Switch constructions in both single-pole, double-throw and single-pole, single-throw versions are disclosed.

Quiet switching apparatus and method of operation

A slide switch assembly having a slide contact movable by a slide actuator across aligned flat blade contacts of a plurality of electrical terminals fixed in position between complemental halves of an inner housing disposed within an outer housing. The slide actuator and outer housing include complemental detents providing a tactile indication of the attainment by the slide contact of a predetermined switch position relative to the fixed blade contacts. The inner housing includes a pair of resilient, oppositely extending cantilever members engaged upon the slide actuator to bias the complemental detents together to enhance the tactile indication. The arrangement eliminates coil springs, centering balls and the like. The inner housing halves and outer housing are made of plastic material whose resilience is utilized to snap fit them together without the use of conventional fasteners.

Slide switch

A four-way electrical switch having a die-cast, metal housing, a set of fixed-contacts disposed in the base of said housing and a central movable-contact assembly disposed within the housing above the fixed-contacts. The die-cast housing serves as a ground contact for the switch. Various provisions are disclosed for assuring good electrical connection between the contacts. Additionally, a mechanical strain relief structure is disclosed.
