Used with a Power Distribution Board (PDB) - 4 Channels, it controls the ON/OFF state of the corresponding channel, thereby achieving the function of switch control. The Self-Locking Button Switch with SH1.0 Connector is a switch device that can be connected to SW0~4 on the Power Distribution Board (PDB) to control the switch of electric devices. Pressing the button down connects the circuit; pressing it again pops it up and disconnects the circuit. When the Self-Locking Button Switch is connected to SW1~4, it's necessary to ensure that the maximum current of the electric devices in each corresponding channel does not exceed 1A. When the Self-Locking Button Switch is connected to the SW0, it's necessary to ensure that the sum of the maximum currents of all electric devices does not exceed 1A. Secured with two M2 screws (screws not included). Consideration: Please do not forcefully twist the connectors to avoid wires loosening or detaching.
