Adjustable cycling switch for electric range

A cycling mechanism for a thermally actuated load switch comprising:

• (a) a pivot block means adapted for being pivotably mounted on said switch;
• (b) as adjustment arm having one end thereof rigidly anchored to said block means and extending therefrom in cantilever;
• (c) a resilient contact blade having one end anchored to said block means and extending in cantilever therefrom, said contact blade having an electrical contact provided on the free end thereof;
• (d) electrical heater means associated with said pivot block means and movable therewith, said heater means operable, upon flow of a certain wattage of current therethrough, to effect movement of said electrical contact with respect to said pivot block means;
• and
• (e) electrical terminal means connected with said contact blade and said heater means and adapted for external circuit connection therewith.

A thermally actuated switch assembly for cycling current to a load comprising:

• (a) housing means;
• (b) a swing switch means adapted for connection to one side of a power line and operable upon user actuation to make connection with a first load connecting terminal;
• (c) a second load connecting terminal isolated from said first terminal;
• (d) insulated block means mounted for pivotal movement on said housing means;
• (e) user adjustable means operable to apply a reload torque in one direction on said block means;
• (f) a stationary electrical switch contact mounted on said housing means and adapted for connection to the side of a power line opposite said one side;
• (g) a first resilient flexible electrically conductive lead means connected between one of said first and second load terminals and said block means;
• (h) a switch contact blade having one end thereof anchored to said block means with a movable contact thereon said one end and disposed adjacent said stationary contact;
• (i) thermally responsive actuator means operable upon being heated and cooled to cycle said contact blade between a position making and a position breaking circuit with said movable and stationary contacts;
• (j) heater means connected in circuit with said flexible lead means and said movable contact means and operable upon making of said movable and stationary contact means and current flow therethrough to effect heating of said actuator means;
• (k) calibration means operable for adjustably biasing said contact blade;
• and,
• (l) second electrically conductive means connecting said first lead means with one of said second and first load terminals and said blade means,
• wherein said block means, said contact blade, movable contact, said first and second means, said calibration means, and said user adjustable preload means are assembled as a subassembly for said pivotal mounting on said housing means.

An electrical control assembly comprising:

• (a) housing defining a wall portion;
• (b) circuit means mounted in solid housing means including a set of electrical contacts operable to perform an electrical control function;
• (c) a plurality of apertures formed in said wall means;
• (d) detent means formed in said housing means adjacent said aperture;
• (e) a connector terminal formed from generally thin flat stock and having
• (i) a first resilient tab formed integrally therewith and offset therefrom;
• (ii) a second tab spaced from said first tab formed integrally therewith and offset therefrom;
• (iii) a guide portion received in said aperture;
• (iv) a blade portion extending externally through said aperture;
• (f) said housing means defining a channel having a detent surface formed therein and a stop surface spaced from said detent surface, wherein said detent surface and said stop surface are generally aligned with said aperture;
• (g) said terminal assembled to said housing means by deflecting said first tab over said stop surface to engages said detent surface wherein said second stab is biased against said stop surface retaining said terminal in said housing means with said blade portion extending outwardly therefrom and said guide portion received in said aperture;
• and
• (h) lead means connecting said connector terminal to said switch means.
