Abstract
The bimetal thermoswitch consists of an electrically insulating, flat carrier (1), at least two electric terminals (3, 4), which are secured to the carrier (1) and are respectively connected to a fixed contact (10), which is mounted on the carrier, and to a contact spring (8), which is secured at one end to the carrier (1) and at its other end carries a movable contact element (9), which cooperates with the fixed contact (10). The carrier (1) consists of an alumina ceramic slab.
Claims49
A bimetal thermoswitch comprising:
- an electrically insulating flat carrier formed of a thin alumina ceramic slab;
- at least two electrical terminals connected to said carrier in an electrically isolated configuration;
- a fixed electrical contact connected to a first of said electrical terminals;
- a contact spring having one end connected to a second of said electrical terminals, said contact spring having an electrical contact element disposed on an opposite end;
- bimetal element means for moving said contact spring in a direction transverse to the plane of said carrier in response to changes in temperature;
- a shunt resistor connected at one end to said fixed contact and at another end to said second of said electrical terminals;
- and
- a series resistor connected at one end to said contact spring and at another end to said second of said electrical terminals.
