An electrical switch (100) comprising a body (110), three control terminals (121-123) and a common terminal (134) for external connection, and a movable contact (130) for establishing connection between the control terminals (121-123) and the common terminal (123). The movable contact (130) has one end (134) acting as the common terminal (134) and three opposite ends (131-133) pivotable to connect to the control terminals (121-123) respectively. Each opposite end (131/132/133) is pivotable between a first position in contact with the corresponding control terminal (121/122/123) and a second position off the corresponding control terminal (121/122/123). A switching member (140) is supported for pivoting the opposite ends (131-133) of the movable contact (130) to establish the said connection. A single metal heat sink (160) is located within the body (110) for contact by the opposite ends (131-133) when they are in the second positions.
