A switching element (40, 40') for use in a snap-acting electrical switch (10) has a pair of outer legs (40a, 40b; 40a', 40b') and a center leg (40c) extending in substantially the same direction from a junction portion. The outer legs have a semi-annular band portion which blend together at the junction portion and a center leg at one end of the band portion. A mounting portion extends from the other end of the semi-annular band portion and is provided with mounting apertures (40k, 40l) for placement on mounting posts (18, 20) in a warped, stressed condition. A strengthening portion (40n, 40r) is formed in each semi-annular band portion, preferably along the outer portion thereof, i.e., the outer portion being away from the junction portion. An electrical contact (32) is mounted on the distal free end of the center leg for snap-movement between a pair of stationary electrical contacts (28b, 30b).
