above the the switch class that is customised...

you can use it like...

<AH_LocalSwitch activeSwitch={this.state.activeSwitchValue} setActiveSwitch={this.btnActionSetActiveSwitch} text1='Value1' text2='Value2' // activeSwitch={1} switchWidth={200} switchHeight={60} switchdirection='ltr' switchBorderRadius={0} switchSpeedChange={500} switchBorderColor={'#F0F0F0'} switchBackgroundColor={'#F0F0F0'} btnBorderColor={theme.appColor.color} btnBackgroundColor={theme.appColor.color} fontColor={theme.gray.color} activeFontColor={'#fff'} switchBorderRadius={5} />

`btnActionSetActiveSwitch = async (data) => {

    if (data === 1) {
        this.setState({
            activeSwitchValue: 2,
        })
    } else {
        this.setState({
            activeSwitchValue: 1,
        })
    }
}`

this.state.activeSwitchValue is the value that can be used to changed the value of switch.
