Abstract

An integral switch connector with remote actuator has a plurality of conductive terminals disposed within a switch housing. A slide member is remotely biased to make or break contact between contact arms to switch voltage between terminals. A connector disposed within switch housing provides connection to a remote apparatus. The remote actuator has a snap-action feature, to bias the slide member independently of the speed of movement of the manual biasing means. Movement of the actuator assembly biases a non-conductive actuator rod disposed within a non-conductive sleeve, to bias the slide member within the switch housing to make or break electrical communication between terminals. A spring disposed between the slide member and the switch housing breaks electrical contact between terminals should the actuator rod fail. A link coupling provides a removable connection between rod and sleeve at a location between actuator and switch assemblies.

(f) an elongated non-conductive, flexible external retaining sleeve, one end operatively secured to said switch housing;

(g) an elongated non-conductive, flexible actuator rod slidably received within said retaining sleeve, one end of said actuator rod operatively secured to said first slide member;

(h) a remote actuator housing, the opposite end of said retaining sleeve operatively secured to said actuator housing;

(i) a second slide member disposed at least partially within said actuator housing, the opposite end of said actuator rod operatively secured to said second slide member;

(j) means to manually bias said second slide member operatively secured to said actuator rod to selectively extend and retract said first slide member to remotely bias said contact arms to make and break electrical communication between at least one of said first and second plurality of conductive terminals, wherein the speed of movement between said first and second operative positions of said contact arms is independent of the speed of movement of said means to manually bias said second slide member.

2. The apparatus of claim 1, wherein the means to manually bias said second slide member comprises:

a toggle arm, pivotally secured to said actuator housing;

the second slide member, slidably disposed in said actuator housing for travel between said first and second operative positions;

an unlocking cam member with spaced protrusions and opposed, inclined cam surfaces, said unlocking cam member slidably disposed in said actuator housing and responsive to manual actuation of said toggle arm;

a biasing means disposed between ends of said second slide member, said biasing means responsive to movement of one of said spaced protrusions of said unlocking cam member and one of said ends of said second slide member;

a resilient member, resiliently disposed between said actuator housing and said second slide member;

a raised boss centrally disposed within said actuator housing, wherein manual actuation of said toggle arm biases said unlocking cam member to compress said biasing means between one of said protrusions on said unlocking cam member and one of said ends on said second slide member until one of said inclined cam surfaces progressively compresses said resilient member to sufficiently traverse said resilient member over said raised boss, to release said compressed biasing means to rapidly traverse said second slide member between first and second operative positions, independently of the speed of movement of said toggle arm.

3. The apparatus of claim 2, wherein the toggle arm is operatively positioned to be manually biased in an arc whose principal direction of travel is approximately parallel to the movement of said second slide member between first and second operative positions within said actuator housing.

4. The apparatus of claim 2, wherein a link arm is pivotally secured at one end to said toggle arm, and is pivotally secured at its opposite end to said unlocking cam member in a manner to be operatively positioned to translate movement of said toggle arm pivotally secured to said actuator housing in an arc whose principal direction of travel is approximately tangent to the movement of said second slide member between first and second operative positions.

5. The apparatus of claim 1, wherein a spring member is disposed between said switch housing and said first slide member, to bias said first slide member from the first operative position to the second operative position to break electrical communication between at least one of said contact arms and at least one of the first plurality of conductive terminals should said actuator rod fail.

6. The apparatus of claim 1, wherein the portion of first slide member disposed within said switch housing is tapered in the area of engagement with the contact arms, and the contact arms are formed to engage the tapered area to expand at least one of said contact arms to make contact with at least one of said first plurality of conductive terminals upon extension of said first slide member to said first operative position, and to release said contact arms to break contact with said first plurality of conductive terminals upon retraction of said first slide member to said second operative position.

7. The apparatus of claim 1, wherein external terminal prongs are disposed within the switch housing to receive a female socket thereon to provide electrical connection between at least one of said first and second plurality of conductive terminals and said female socket.

8. The apparatus of claim 1, wherein internal terminal receptacles are disposed within the switch housing to receive a male plug therein to provide electrical connection between at least one of said first and second plurality of conductive terminals and said male plug.

9. The apparatus of claim 1, wherein at least one of the first and second plurality of conductive terminals extend beyond said switch housing for soldering to an external electrical connection.

10. The apparatus of claim 9, wherein at least a portion of said receptacle housing is molded of a temperature resistant thermoset plastic material to resist damage to said switch housing during soldering.

11. The apparatus of claim 1, wherein at least one of the first and second plurality of conductive terminals disposed within said switch housing is adapted to extend beyond said switch housing to be flow soldered to a substrate.

12. The apparatus of claim 1, wherein the switch housing is provided with internal opposed guide means, positioned to slidably receive and guide said first slide member, between said first and second operative positions.

13. The apparatus of claim 1, wherein the switch housing is provided with a non-conductive internal boss positioned between the contact arms to limit travel of the contact arms when said first slide member is retracted to said second operative position to avoid contact of one said contact arm with another.
