The switching of support and resistance means that the structure of price highs and lows has changed. As long as the previous low is not broken, it will act as support; as long as the previous high is not surpassed, it will act as resistance. However, once these key levels are "closed below" or "effectively broken", the original support and resistance levels will have their roles reversed. The essence of trading is betting with the trend. And the premise of "following the trend" is that the high and low structure has not been broken. Continue short until the previous high is broken, and continue long until the previous low is broken. If these structures are breached, and you still insist on finding an entry point in the original direction, then you're just holding onto losing positions and suffering the consequences.
