230v Sump float switch to power 115v pump

Hi, I have a 230v float switch (Dayton 3BY77) that I want to use on a 115v pump (.5hp) with a 115v outlet. Not sure how to modify the switch plug?

Both the incoming power and the pump are 120v...the switch has 230v plugs though

The pug has a built in receptacle for pump correct? Best is to buy the correct switch. Would cost a bit but you could make a couple of adapters. Basically six inches of service cord with a plug on one end and a female cord cap on the other. You'd need two. One would have a 120 volt plug and a female cord cap to match the plug on your switch. The other would have a plug to match the female receptacle on the pump cord cap and a female 120v cord cap. Uneducated guess maybe $50 for parts so why not just add a bit and get the correct switch.
