Abstract
The contact spring (7) comprises two outer lamellar branches (71, 72) and two inner lamellar branches (73, 74) subjected to the action of a prebiasing member (6) integral with an actuating member. Two stationary stops (9, 10) are arranged on either side of a transverse connection portion (77) of the spring (7) and have each a plane contact surface extending at least throughout the length of the portion (77) and susceptible of extension throughout one portion of the length of the two outer branches of the spring (7). The actuation force, as well as the stroke of the prebiased spring, may be very important with respect to the size of the switch, the electric contact being suddenly established with an appreciable contact force.
