I'd consider modifying your design to put the switches horizontal and use roller lever operated by the green bits as a cam. The way you have it relies on the carriage stopping fast enough not to overstress the switch. Hitting the limit a few times could compromise the switch reliability.
Agree with Irving.!!. . . BUT . . . there's another plus to using Cam or ramp.? You only need 1 switch which travels not 2.!!
