Claims
- 1. A dial assembly comprising:
a first member having a pivot pin attached thereto; a dial magnet rotatably mounted on said pivot pin; a reed switch assembly positioned operatively adjacent to said dial magnet comprising: a reed switch; and a bias magnet positioned such as said reed switch is held in the first position when the poles of said dial and bias magnets are in a first orientation and will be held in a second position when the poles of the dial magnet and bias magnet are in a second orientation.
- 2. A dial assembly of claim 1 further comprising a cover defining a receptacle for receiving said reed switch assembly.
- 3. A dial assembly comprising of claim 1 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 4. A dial assembly comprising of claim 2 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 5. A dial assembly comprising:
a first member having a pivot pin attached thereto; a dial magnet rotatably mounted on said pivot pin; a second member attached to said first member to form a cover; a reed switch assembly removably positioned operatively adjacent to said dial magnet comprising: a reed switch; and a bias magnet positioned such as said reed switch is held in the first position when the poles of said dial and bias magnets are in a first orientation and will be held in a second position when the poles of the dial magnet and bias magnet are in a second orientation.
- 6. A dial assembly of claim 5 further wherein said first member defines a receptacle for receiving said reed switch assembly.
- 7. A dial assembly of claim 6 further wherein said second member defines a receptacle for receiving said reed switch assembly.
- 8. A dial assembly comprising of claim 5 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 9. A dial assembly comprising of claim 6 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 10. A dial assembly comprising of claim 7 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 11. A gauge comprising:
(a) a gauge assembly having
(i) a gauge head; (ii) a support member extending from said gauge head; (iii) a transmitting shaft having a first end and a second end rotatable in said support member; (iv) a tank magnet attached to said first end of said transmitting shaft; (v) a float arm linked to said transmitting shaft such that movement of said float arm results in rotation of said transmitting shaft; (b) a dial assembly mounted on said gauge assembly having:
(i) a first member having a pivot pin attached thereto; (ii) a dial magnet rotatably mounted on said pivot pin; (iii) a reed switch assembly positioned operatively adjacent to said dial magnet comprising: (iv) a reed switch; and v) a bias magnet positioned such as said reed switch is held in the first position when the poles of said dial and bias magnets are in a first orientation and will be held in a second position when the poles of the dial magnet and bias magnet are in a second orientation.
- 12. A dial assembly of claim 11 further comprising a cover defining a receptacle for receiving said reed switch assembly.
- 13. A dial assembly comprising of claim 12 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
- 14. A dial assembly comprising of claim 13 wherein in said first position of said reed switch the reeds of said reed switch are in contact.
