Form then it will be possible to add labelLeft and labelRight props and pass a String to it to define your custom labels. An example below: 

import React, { Component, Fragment } from "react";

import { InputSwitch } from "mdbreact";

class App extends Component {

state = {

switch1: true,

switch2: false

}

handleSwitchChange= (nr) => {

let switchNumber =`switch${nr}`;

this.setState({

[switchNumber]: !this.state[switchNumber]

});

}

render() {

return (

<Fragment>

<InputSwitch labelLeft="No" labelRight="Yes" checked={this.state.switch1} onChange={this.handleSwitchChange} />

<InputSwitch checked={this.state.switch2} onChange={this.handleSwitchChange} />

</Fragment>

);

}

}

export default App;

If you have more sugesstion, please post them bellow.

Best,
