A temperature operated switch construction, terminal block therefor and methods of making the same are provided, the switch construction comprising a housing, a movable switch arm carried in the housing, a temperature actuated unit disposed in the housing and being operatively interconnected to the switch arm to cause movement of the arm between operating positions thereof in relation to the temperature being sensed by the temperature actuated unit, the housing comprising a main part and a removable terminal block carried by the main part, the terminal block carrying a switch unit that is operatively associated with the switch arm so that the switch unit is in a first condition thereof when the switch arm is in a first operating position thereof and the switch unit is in a second condition thereof when the switch arm is in a second operating position thereof, the switch unit comprising a reed switch and the switch arm carrying a magnet for operating the reed switch to the conditions thereof as the switch arm is moved to the positions thereof.
In a temperature operated switch construction comprising a housing means, a first movable switch arm carried in said housing means, temperature actuated means disposed in said housing means and being operatively interconnected to said first switch arm to cause movement of said first switch arm between operating positions thereof in relation to the temperature being sensed by said temperature actuated means, said housing means comprising a main part and a removable terminal block carried by said main part, said terminal block carrying a first switch means that is operatively associated with said first switch arm so that said first switch means is in a first condition thereof when said first switch arm is in a first operating position thereof and said first switch means is in a second condition thereof when said first switch arm is in a second operating position thereof, said switch construction comprising a second movable switch arm carried by said housing means and being operatively interconnected to said second switch arm to cause movement of said second switch arm between operating positions thereof in relation to the condition of said actuator means, and a second removable terminal block carried by said main part of said housing means, said second terminal block carrying a second switch means that is operatively associated with said second switch arm so that said second switch means is in a first condition thereof when said second switch arm is in a first operating position thereof and said second switch means is in a second condition thereof when said second switch arm is in a second operating position thereof, the improvement wherein said first switch means comprises a first reed switch means and wherein said first switch arm carries a first magnet means for operating said first reed switch means to said conditions thereof as said first switch arm is moved to said positions thereof, said second switch means comprising a second reed switch means, said second switch arm carrying a second magnet means for operating said second reed switch means to said conditions thereof as said second switch arm is moved to said positions thereof in a direction that is generally parallel to said second reed switch means.
In a method of making a temperature operated switch construction comprising a housing means, a first movable switch arm carried in said housing means, temperature actuated means disposed in said housing means and being operatively interconnected to said first switch arm to cause movement of said first switch arm between operating positions thereof in relation to the temperature being sensed by said temperature activated means, said housing means comprising a main part and a first removable terminal block carried by said main part, said first terminal block carrying a first switch means that is operatively associated with said first switch arm so that said first switch means is in a first condition thereof when said first switch arm is in a first operating position thereof and said first switch means is in a second condition thereof when said first switch arm is in a second operating position thereof, said switch construction comprising a second movable switch arm carried by said housing means, actuator means carried by said housing means and being operatively interconnected to said second switch arm to cause movement of said second switch arm between operating positions thereof in relation to the condition of said actuator means, and a second removable terminal block carried by said main part of said housing means, said second terminal block carrying a second switch means that is operatively associated with said second switch arm so that said second switch means is in a first condition thereof when said second switch arm is in a first operating position thereof and said second switch means is in a second condition thereof when said second switch arm is in a second operating position thereof, the improvement comprising the steps of forming said first switch means to comprise a first reed switch means, disposing a first magnet means on said first switch arm to be carried thereby for operating said first reed switch means to said conditions thereof as said first switch arm is moved to said positions thereof, forming said second switch means to comprise a second reed switch means, and disposing a second magnet means on said second switch arm to be carried thereby for operating said second reed switch means to said conditions thereof as said second switch arm is moved to said positions thereof in a direction that is generally parallel to said second reed switch means.
