Abstract
A capacitor unit includes a housing having a pair of conventional electrical terminals. Contained within the housing are a pair of capacitors connected in parallel to the two terminals. One of the capacitors is connected to one of the terminals by a relatively thin wire which passes to the terminal through an anchoring location. The wire is connected in such a fashion that rotation of the terminal by a service man will break it. This reduces the capacitance of the unit to that of the remaining capacitor.
Claims9
An adjustable capacitor unit which comprises:
- a housing;
- first and second capacitors enclosed within said housing, each of said capacitors comprising a first capacitor plate and a second capacitor plate, the second plates of said capacitors being electrically common;
- at least one selectively rotatable electrical terminal carried by a portion of said housing;
- a first electrical lead connected between the first plate of said first capacitor and said electrical terminal;
- and
- a second electrical lead connected between the first plate of said second capacitor and said electrical terminal whereby said first and second capacitors are in parallel electrical relationship, said second electrical lead having an end secured to said terminal whereby the lead is broken upon selective rotation of said terminal.
