Abstract
A temperature sensitive switch having a switch housing containing switch contacts and electrical leads, an arched bimetal disc, whose dome height changes under temperature influence, a guiding disc with a centrally located and freely moveable transfer pin, which transfers movements of the bimetal disc to the switch contacts, a potlike support, and a heat transfer plate placed between guiding disc and potlike support, and characterized by an opening at the bottom of the potlike container, to allow direct heat access to the heat transfer plate.
Claims9
A temperature sensitive switch comprising :
- a. a switch housing containing at least a pair of switch contacts,
- b. an arched bimetal disc, whose dome height changes under temperature influence,
- c. a guiding disc with a centrally located and freely movable transfer pin, which transfers movements of the bimetal disc to at least one of said switch contacts to effect relative movement thereof with respect to said other contact,
- d. a potlike support mounted on said switch housing, and
- e. a heat transfer plate having predetermined heat transfer characteristics placed between guiding disc and said potlike support, and characterized by an opening at the bottom of said potlike support, to allow direct heat access to the heat transfer plate.
A temperature sensitive switch comprising a switch housing containing at least first and second switch contacts, at least one of said switch contacts being mounted for movement with respect to the other;
- a potlike support mounted on said switch housing and having an opening in the bottom thereof;
- a heat transfer disc having predetermined heat transfer characteristics disposed within said potlike support so as to form a cover for the opening in the bottom thereof, thereby providing direct heat transfer to said heat transfer disc from outside said potlike support;
- an arched bimetal disc supported on said heat transfer disc, the dome height of said disc changing with temperature;
- and transfer means including a transfer pin for transferring movements of said bimetal disc to said one switch contact.
