An improved electric torch or flashlight of the type having an elongated case, a bulb and a battery source of electrical energy is disclosed. The flashlight includes a pressure-receiving surface, which may be in the form of a series of flexible segments formed of case material at an end of the case, a pressure-transmitting surface, which may be in the form of a nib at the end of a right-angle bend formed in the flexible segment, and a complementary surface, which may be a portion of the bulb. Radial pressure on the segments results in a longitudinal displacement of the complementary surface, which controls closing of the electrical circuit and illumination of the bulb.
