ABSTRACT:
A snap switch comprises a control button, a control rod slidable with the control button via a spring, two pairs of contacts associated, respectively, with two pairs of terminals, the two contacts of each pair of contacts being connectable by resilient conducting means under the action of a setting spring fixed to the control rod and to these resilient conducting means. The two contacts of one pair of contacts are borne by two pivotable conducting plates, biased by resilient means for connecting the two contacts borne by the conducting plates to their respective terminals. The conducting plates can be pivoted under the action of the control button and against the action of the resilient biasing means for disconnecting the two contacts borne by the conducting plates from their respective terminals.
