Abstract

The subject of this invention is an electric switch with thermostatic action and auto-preservation of the activated position, capable of being inserted in the power supply circuit of a load whose functioning generates heat; it includes a box (10), from which two terminal connecting stems exit (1,2) to which a fixed contact (4) and a moveable contact (5) are connected, carried by an oscillating arm (9), as well as a bi-metal temperature sensitive element (3), which maintains said fixed and moveable contacts (4, 5) in a normally closed position, and in parallel to said fixed and moveable contacts (4,5), and a resistive element (6) with a positive temperature coefficient (PTC).
