  • Circuit breaker by-pass element
    Patent number: 4528479
    Abstract: A circuit breaker for a rapid-start fluorescent lamp includes a pair of electrical conductors sealed into a glass bottle, a bimetal switch within the bottle having one end affixed and the other end contacting the pair of electrical conductors and a meltable by-pass element shunting the pair of electrical conductors and formed of a material having a relatively high cold resistivity and a low temperature coefficient of resistance.

  • Circuit breaker with parallel shorting element
    Patent number: 4171519
    Abstract: A circuit breaker has a thermally sensitive bimetal connected across two lead-in wires in a glass envelope. An electrically conductive bypass element is in parallel with the bimetal and shorts it out. The bypass element can be removed from the circuit by melting it by means of a short duration pulse of high electric current. The bimetal contains means to prevent its ends from welding together should an arc occur when the bypass element is melted.
