Operating Modes This section explains the three operating modes — Mode 1, Mode 2 and Mode H — along with the built-in overheat protection feature. Mode 1 When a press signal is detected, the switch turns ON for 15 seconds then automatically turns OFF again. The ON time is extended by a further 15 seconds every time an additional press is detected. Compatibility For use with the Camtraptions Wireless PIR Sensor v3 (purchased after 18th January 2021), using video programs 1 , 2 or 3 . Mode 2 First press turns the switch ON , second press turns the switch OFF . Compatibility For use with: Camtraptions Wireless PIR Sensor v3 (purchased at any time), using video programs 4 , 5 or 6 . Camtraptions PIR Sensor v2 programs 14 , 16 , 18 , 20 , 22 , 24 . Mode H The switch is ON while the press signal is held. Overheat Protection The switch has an inbuilt cut-out feature that automatically turns it off if it starts to overheat. This ensures that the switch itself does not get damaged. In practice, the switch can support devices drawing up to around 1.5 Amps for a prolonged period of time without overheating. If a device draws more current than 1.5 Amps , it may be necessary to use two USB Switches in parallel.
