The disclosure relates to a cam disc and to a spring deflection switch having a cam disc for a spring-loaded drive, wherein the cam disc includes a first, second and third circumferential region, each having at least one corresponding radial extension, for actuating a pushbutton including a switching hysteresis. The at least one second radial extension is larger than the at least one third radial extension, which in turn is larger than the at least one first radial extension. The pushbutton can interact with the cam disc in the spring deflection switch such that when the pushbutton is applied by the first circumferential region, the switching contact assumes a first switching position, and when the pushbutton is applied by the second circumferential region, the switching contact assumes a second switching position, and when the pushbutton is applied by the third circumferential region, the switching contact remains in the switching position assumed earlier.
