This article describes six different touchscreen based toggle switches allowing the control of two state (ON/OFF) devices. The user interfaces, ranging from button type toggles to sliding toggles are described and compared. A usability test with 15 subjects was conducted. Error rates, user preferences and subjective satisfaction ratings were collected. Results indicate that all the toggles described here can be used with low error rates. The sliding toggles were rated harder to use and were least preferred. Individual differences in personal preference were shown to be very large. It was also observed that users spontaneously or after one trial use a sliding motion to activate a control showing a sliding affordance.
