M8 Subsea Switch

Description

This switch is installed on the underwater equipment and can be used to switch the circuit without the need to open the watertight enclosures. The thread specification is M8x1, and it can withstand pressures up to 1000 meters deep. By turning the knob, you can switch between two positions, on and off, with positive positioning. Two wires, one blue and one green, are connected. When a high-current circuit switch is needed, a relay or MOS switch circuit can be connected. Turn clockwise to fully connect, and counterclockwise to disconnect.

FAQ

● After using the switch in murky waters for a while, I sense some resistance while rotating. Is this normal?
Yes, this is normal. Impurities or salt crystals might have entered small crevices. You can alleviate this by soaking the switch in warm water and rotating it several times to dislodge any impurities.
● Can this switch handle high-current power sources?
No, you should employ MOS switches or relays to manage high voltage and high current power sources.
● Will the knob come off due to severe vibration?
No, the knob has a pin for positive positioning.
● Can you provide an electrical schematic for the switch?
No, it's a physical on-off switch, so it can be simply referred to as a switch.
● Can this switch be used in shallow water or in the air?
Yes, it is suitable for usage in water depths ranging from 0 to 1000 meters, as well as in the air.
● Will forcefully twisting the knob cause damage?
No, it has a pin for positive positioning, but it is not recommended to apply excessive force as it may damage the aluminum knob.
