The switch according to claim 1, wherein the first and second legs have respective planar surfaces, being angled to each other. 3. The switch according to claim 1, wherein the heart-shaped stepping recess is integrally formed with the stem, and the locating cantilever is provided with a first hand mounted in the housing and a second hand slidably inserting into the heart-shaped stepping recess. 4. The switch according to claim 1, wherein the conducting unit further comprises a third terminal, a lamp having two pins to be connected with the second and the third terminals respectively, and a second conducting leaf having one end connecting with the third terminal; and wherein the stem is provided with a branch to carry one pin of the lamp into conduction with the second conducting leaf. 5. The switch according to claim 1, wherein the enabling rest is provided with a platform for supporting the resting tail and an oblique lower surface for guiding the resting tail.
