One problem, the switch position and the received state have to be in sync. You send a pulse whenever the switch turns on - the receiving device also requires a pulse to turn off, no? Consecutive pulses turn it on/off/on/off...? So your fixed toggle must send a pulse when it is turned off as well. Therefore, the receiving device can not really know the actual state of the switch. It depends on the receiving device assuming that the physical switch is in some known position at boot time.
